I like attaching RaspberryPis to TVs to make them do different kinds of kiosk things. Pis are impossible to find, and pretty much all of our smart TVs are a) already running Linux and b) more than capable of doing more or less what a Pi can do. Hot gluing an SBC onto an already embedded linux computer - just to join them with an HDMI cable - seems like a huge waste of perfectly usable hardware. However, I've run out of ideas how to get into the Linux part of this Vizio "smart" TV. Suggestions of what to do next, where to go looking, or if other brands are perhaps easier to deal with are welcome. thanks! Here's what I do have: * Full serial (UART) console output via a BusPirate, with lots and lots of output. * The CPU is a Mediatek 5583, which is likely just a variant of the 558x made for Vizio? and running an ubuntu-like Linux distro. * onboard storage is 4GB of HS400 eMMC * bootloader is U-Boot 2011.06 * the firmware updater file downloaded from Vizio. the binary blob file looks like two sections: first is a JWT and then what seems like the actual firmware - encrypted. I assume encrypted because the entire remainder of the ~530MB looks like noise. Here's what I know from reading the console output: * As U-Boot does, the first thing it does is gets moved to RAM. It then reads some basic configuration from EEPROM (somewhere) getting the network MAC address (seems to be set in software rather than burned into the hardware) and then immediately disables the UART input: !!!! enable_uart_rx=[0] !!!! Disable UART In: serial Out: serial Err: serial * a USB flash drive will be automatically mounted if present, and uboot(?) will look for several files like MstarUpgrade.bin, SbootUpgrade.bin, MbootUpgrade.bin, and UrsaUpgrade.bin. * during normal operation, the USB flash drive is mounted at /mnt/usb/sda1. * the custom ubuntu is called "ViziOS" and is version 1.3.432.468.0 * there is a shell and/or busy box available, but it's not accessible because the UART rx is disabled * an external keyboard (at least the only Mac keyboard I have around here) seems to be recognized as a present USB device, but is almost always otherwise ignored - it can sometimes be used for input * command injection by using backticks around the wireless network name does _not_ appear to have any effect in this version of the firmware, although it was apparently possible in older versions * Likewise, vulnerabilities around https://<ip_address>:7345/scpl/ don't seem to be present anymore * Despite being factory reset and never connected to Netflix ever, since I won't let the tv connect to the internet (it will automatically upgrade the firmware), it (internally) loses its mind because it can't send telemetry to Netflix. That's another big reason I'm not at all satisfied to just "throw a chromecast/etc onto an HDMI port and be done with it" - I want to turn off all the telemetry crap. * There are a couple of "secretKey" messages that might be interesting/useful, but I don't know what to do with them [SECRETKEY DBG]in func:getSecretKey line:94 strModelName=Vizio_D32f-J04 [SECRETKEY DBG]out func:getSecretKey line:104 (hashed)strKey=dcaa76a2 strKey.length()=48 * When there is no USB drive present, the following network ports are listening: 7345/tcp 8005/tcp 9223/tcp 56789/tcp 56790/tcp * However, when the drive is removed, 36675/tcp is also listening. * Lastly, there's old firmware sourcecode on github, but honestly I have no idea what to do with it or if I even could. There is no obviously accessible EEPROM on the board. I suspect that it's probably part of the SOC. Both the eMMC and the SOC are BGA chips, so there's no way to probe them directly even if I understood how to do such a thing.

Summary MediaTek rumored to be partnering up with NVIDIA for developing low power GPU for their mobile SoC in early 2024 Quotes My thoughts I don't have much to say about the NVIDIA x MediaTek news. I kinda don't think this is a big surprise, in fact they did that RTX on ARM demo with a MediaTek chip back in 2021 which was during the NVIDIA ARM acquisition drama, but at the same time I do hope this is not NVIDIA trying to find a loophole to strangle ARM chips market silently and I hope this doesn't spark any gatekeeping problem for basically everyone else that are partnering up with MediaTek for their mobile chip or anything else, especially that MediaTek still have some partnership with AMD in some spaces like Network solution for AMD mobile platforms. But we shall see whether this is going to be actually happening or not Sources - https://www.digitimes.com/news/a20230515PD212/gpu-mediatek-nvidia.html - https://www.tomshardware.com/news/mediatek-to-adopt-nvidia-gpu-tech-report - https://9to5google.com/2023/05/16/mediatek-nvidia-gpu-report/

I just built a new Desktop PC for Christmas and the MediaTek MT7922 on my motherboard is not being detected. Its a Wireless card that is built into the GIGABYTE B650I AORUS ULTRA motherboard. The wireless card WAS working when I finished building the PC, but then the toggle for WiFi and Bluetooth in Fedora 37 just vanished from settings and the control panel. I have reinstalled Fedora 37 to hopefully rectify the issues, but to no avail. In the meantime, I have internet connection via Ethernet, but as a temporary solution. Someone from the Fedora Discord server told me that its not a driver issue but something in the stack. I'm a Linux newbie so I don't understand what they mean by that. Here is my build probe https://linux-hardware.org/?probe=3c25f43c23

Apple had a considerably bitter legal fights with Qualcomm over royalty rights for their wireless architecture that in which caused Qualcomm to withhold software for Apple's device prototype modems. This has lead Apple to endearingly want to drop Qualcomm's wireless chip manufacturing contractor arm as a supplier. Suppliers for Apple's mobile device modem components to just either just existing supplier intel or in junction with Mediatek. Qualcomm is the biggest supplier of mobile chips, with nearly all Flagship phones in the US running Qualcomm due to its high compatibility with it's wireless standard and with the US wanting to roll out 5G. The dispute is ongoing since that Apple has stop reimbursing manufacturers for Qualcomm royalties, which then imposes that those royalties were unpaid by Apple. Qualcomm chips are also very refined in matching the standards set out by Qualcomm. With some phones reaching nearly 1 gigabit in download speed while both Intel and MediaTek has yet to prove to reach just as fast. A $5 billion market is about to change for manufacturers, MediaTek has lots to benefit as they have been in the low end mobile market, making cheaper models of Qualcomm's standard than competitors. An investment pushed by Apple, as Apple normally does with manufacturers to boost quality and quantity of manufacturing, can improve MediaTek portfolio.

Source:https://www.chinamobilemag.de/news/erstes-helio-x30-antutu-ergebnis.html https://www.mediatek.com/products/smartphones/mediatek-helio-x30 After months of waiting, and with the release of the Meizu pro 7 we finally get a taste of the performance the latest flagship chip from Mediatek. This SoC is vital for Mediatek if they want to compete among the top tire chips offered by Qualcomm,Hisilicon and others. For quite a while now devices based on Mediatek components have been lagging behind their competitor counterparts, either in performance (especially 3D) or thermal/power consumption. The Helios X20 series had notably poor efficiency and had many bugs with 3D games, leading to stuttering even on low settings. The latest chips from Mediatek such as the P25 now offer much improved performance and power efficiency, rivalling the snapdragon 625. The Helios X30 offers 10 cores on a 10 nm process. Specs: 2 High performance A73 cores at 2.6 GHz 4 medium performance A53 cores at 2.2 GHz 4 low power A35 cores at 1.9 GHz PowerVR 7XTP-MT4 at 850MHz The GPU is a massive upgrade over the previous generation. Gist: the total points in antutu is 141.982 which is almost a snapdragon 821. This was more than expected. Mediatek has managed to close the gap with Qualcomm greatly, yet doesn't match or exceed Qualcomm.

Here's "D" immensity in its 1000-level glory (pun intended ). But will the name stick? D-immense Specs: 7nm process 4 x A77 + 4 x A55 Mali G77 MP9 GPU 2B+3S+1T APU/NPU up to 64GB LPDDR4X RAM (crap that's a lot) 4K60/HEVC/H.264/AV1 video encoding & decoding (only the latter for AV1) 5G modem up to 4.6Gbps down & 2.5Gbps up WiFi 6 & Bluetooth 5.1 support https://www.anandtech.com/show/15155/mediatek-announces-dimensity-1000-soc-back-to-the-highend-with-5g And the craziest thing to me........up to 80 MEGAPIXELS of combined camera resolution. That's like 2 depth/ambient light sensors ("cameras" that don't really do anything except just that) + a 36MP main camera w/ 8K 30fps video + a 24MP "secondary" camera (selfie cam?) with 4K 60fps video + a 12MP wide-angle camera with 5x optical zoom + a secondary 8MP "regular" camera for other stuff (macro, black-and-white, more selfies, night vision, etc., etc.). Not bad for a peak at what insane SoC features we might see coming from Quallcomm, Samsung, and Huawei in the coming year.

Okay, so basically I'd love to know what chipsets are best. Not just in general, but for different price ranges of smartphones, such as mid-range, budget, etc. To start, my phone has a snapdragon 425 (yikes), and it would be great to know how newer budget or mid-range chipsets compare.

What are the threads in a CPU?

Apple has notified Intel that they will not be using Intel's "Sunny Peak" modem for Wi-Fi and Bluetooth. Intel then started working on another platform in hopes to tease Apple into having the modems reappear in 2022 iPhones. Intel has said that Apple was the "main volume driver" for the "Sunny Peak" modems. As for Apple, this means numerous things. Either Apple is going to look to new providers such as MediaTek for wireless connectivity, or Apple will possibly try to bring things back together with Qualcomm.

Hi all, I am having trouble finding a Pump Express Plus charger on the internet for my Umidigi Z Pro. It did not come with one, as I bought it second hand, and I have had no luck finding them online. If anyone knows where I can find one, or a quick charger that will work with the Umi Z Pro, please let me know Preferably it would have a UK plug, however I can always use an adapter.

This is my second ever post on this forum (although I've lurked for a while) and I'm hoping to find anyone willing to help a newbie out! Here goes: I've been pulling my hair out trying to root my WIKO Jerry (running Android 6.0) and so far I've been unsuccessful. I've tried every method I could find but to no avail. I'm completely new to rooting so I might have made some noobish mistakes along the way. What I've done/tried so far: - Unlocked bootloader and enabled USB Debugging in the phone's developer options - Installed ADB/Fastboot drivers (although my device isn't detected in fastboot mode) - Run every 1 click root software solution (including APK's) under the sun (unsuccessfully) - Install MTKdroidTools (which couldn't create a scatter file) - Install Android USB drivers (although I'm unable to install Android Bootloader Interface) Despite the unlocked bootloader/enabled USB debugging I can't get the phone to be recognized by my pc in fastboot mode. ADB devices recognizes the device just fine. Why do I want to root this phone so badly? I want to be able to recover my files (mostly photos) after a recent (and accidental) factory reset. I tried using Diskdigger but for a full scan I need root access to the file system! Thanks in advance! Any feedback/help/tips are appreciated!

http://anandtech.com/show/9518/the-mobile-cpu-corecount-debate/ Wow! I'm surprised at how well processes (esp. webbrowsing) are able to take advantage of higher core counts. It always seemed to me that the core count race was just a spec race for no good reason, but that's counterintuitively false. As time goes on, I think we'll see more and more designs like the Exynos 7420 and Snapdragon 810 and Mediatek Helio X10/X20 pull away from the weaker processors. There may be a "good enough" lower limit, but as for a higher limit, there seems to be none in terms of core count as it contributes to efficiency.

I don't think HTC understands what a flagship means. Flagship. Singular. One ultimate device for your generation. Thats it. Best you can muster for the release cycle. Yet we have yet another HTC One 'flagship' for Asia. Because HTC thinks making new hardware based off the One over and over will fix the lacklustre reception their phones have been getting this year. In all honesty, maybe this should've been the M9 that HTC sold North America and Europe in the first place. Maybe HTC needs to really take the best of everything and make a single phone. This thing does have a fingerprint scanner, but its not a button. Doesn't make sense, since you still get these god awful double bezels and I can't honestly think that anyone at HTC actually thinks this looks nice anymore. HTC, please get your shit together. No? Yes? Please don't release a HTC One ME9+ now after this...and yes this device is either the ME or ME9 depending on what sources you read. Keep getting confused people, its the HTC way. http://www.engadget.com/2015/06/04/htc-one-me/ http://www.slashgear.com/htc-one-me-sports-htcs-sharpest-display-and-you-cant-have-it-04386756/

First of all Hello everyone, i wanted to make this post for the sole purpose of imposing my opinion over these following (Mobile/Station Cpu's used in Android System). Leave your ideas or replies but dont criticise based on "You cant make posts like these", "This is a repost, im sure of it", "Why should we trust what you say here?". Thanks for understanding, i believe this is a "Legal Post" in the forums, otherwise remove it or lock it. "Samsung": Samsung has been recently well known and congratulated for theyr highly efficient and powerful line of cpu's theyve been constructing for top tier phones. Meizu did use the Exynos 5430 in the MX 4 Pro which i believe is the only outter brand to use this cpu in 2014. Previous generations of the Exynos chip were not impressive which led to some disapointment from the consumers, which expected better products to compete with Snapdragon and Apple "A" line which was built by Samsung adopting the 64-Bitness in Mobile world and therefore demanded more from them, which is pretty comprehensible. So far from last year to currently they presented us with incredibly small (14Nm), energy friendly (Architectural Mapping and Smaller Nodes) and fast chips (64 Bit alongside DDR4 Memory) able to surpass other major brands in green line and innovation terms. This lined up with theyr title of [1º Memory Manufacturer in the World] will make many users probably opt for them in the following years, so hopefully they can achieve the sales and support they deserve to become number 1 in mobile processors line of construction. "Qualcomm": Qualcomm is an old and influential cpu maker in the mobile world, delivering a low end, mid end and high end tier line of mobile chips, to acomodate as many as possible phone models from several brands. Like already divulgated many Android application workers and designers attempt to optimize theyr projects at max to be on pair with Snapdragons as smoothly as possible. Networks are also highly compatible with theyr cpus thanks to the effort of deliverers in the area which work hard to implement advanced connections to minimize network impact and increase bandwidth gain in these processors conjugating pretty well with the integrated Modems. Architecturally speaking these used to be superior to nearly every other mobile cpus, competing in graphical software against the current leader "Nvidia" and battling for maximized core performance versus Apple. Qualcomm is a very trustable enterprise amongst even these, and i cant see a mobile future without them, especially in the top of the line segment where they keep delivering great camera and sensor technologies to the masses. "Mediatek": A not well known company amongst these other manufacturers presented, and then again some people dont trust Taiwanese brands because only South Korean ones are trustable in the Smartphone market. This is not true, due to the simple fact that Mediatek was the first in 2013 to present the world with the news that they were working on the first Octa-Core cpu in the segment. The promise was delivered and they continue to make multi core products delivering acceptable performance to mid range devices which dont break the bank for most people. Theyr like Advanced Micro Devices in the Mobile segment right now, due to the uncertain "unreliable" belief of many users who simply got a more determinate idea over the Exynos or Apple. Theyr territory is largely widespread in the East yet it still lacks some confidence, and it could be a downside for them especially with the implementation of Qualcomm's Snapdragon 600 series which seem to be just as effective, and focused on the mid end segment as well. Hopefully they can impress with better and invest higher in the mobile cpu development. "Nvidia": An obvious choice for most people for the following reason -> "Weez got the fastest and most graphically powerful cpu in the world because if nvidia did it, then its a monstruous beast who cant be beaten". Well the Tegra K1 and X1 so far have proven theyr mighty power in the portable gaming sector. The Nvidia Shield Tablet was a great implementation for them, and showed just how powerful a tablet could get. We all know smartphones cooling solely depends on theyr "Construction quality" and the fabricants sure make some smart moves to reduce as much as possible the heat output from a smartphone after a few hours of playing videos, running benchmarks or just playing demanding titles by lowering the cpu voltage and regulating its power delivery. The Shield Console adopts a good gadget againts this which is a cooling fan. It would be great to expect some watercooling alternative in a few years from now thanks to the amazing constructions talented engineers can come with, to where somewhere between 2019-2021 i think we might see an adaptive cooling solution in the mobile segment, hopefully coming from Nvidia to gives us maximum power for hours and still be chilly to the touch. This is the company to go if your biggest interest in mobile is indeed graphical purposes. "Apple": If it says Apple then most fans wont even think twice before aquiring these, and we cant blame them due to the simple fact that Ios and Iphones/Ipads hardware work like brothers and sisters. In the spec sheet any hardware fan would be "O-o so weak!" but like most of us know that isnt the case, and theyr simple interface alongisde with very well optimized software is a bliss for the cpu's used in theyr products. Recently apple seems to be turning theyr heads to Samsung again for producing theyr Apple A9 cpus in 14nm die size, one more reason to see why Samsung is like a guardian to Apple. I personally dont see Apple and Samsung as rivals, but as partners and many people seem to ignore that fact. The price implement by both companies may be great, but as from now on i can see a reason for it especially if theyll start to adopt (100% company made materials in theyr phones). Apple makes a single line of Iphones all with same specs exept for some minor changes which makes it easier for consumers to aquire a phone from them. Construction is a concern to me, hence why Apple is not a phone i would go because theyr , politely speaking "Fragile". An acceptable company, the most valuable in the world, but they gotta work harder on showing that theyr price is worth the risk. :lol: Hopefully my post makes it easier for someone to choose what phone theyll get based on cpu ideas. Thanks everyone for reading and accepting.
