Based on my experience with other Linux handheld projects, most people prefer to keep Android intact and use Linux as a second option. In the DTB, I also added eMMC support, so you have full access to it from Linux. This means you can dd ev

I tried a Whitedeer WHTG1301 with an A733, but it only uses eMMC as the primary boot device. Now I’ll try another one with an A523 and see if I have better luck there.

Thanks, I’ll check it out. Seems interesting. I usually prefer cheap devices for travel, because you never know when something gets lost, broken, or stolen. This tablet fits that well, Android for the kids or for testing an app, and Linux w

Exactly. The hardware is already powerful enough. An iPad Pro with unlocked virtualization and a proper Linux VM would be an amazing travel dev machine. This is the reason I made this project, and I am still exploring for other tablets with

I used phosh, which is also used by postmarketOS.

The project itself is MIT, meaning the scripts/docs I wrote. Everything else remains under its respective upstream license, GPL, vendor/proprietary blobs, debian packages, firmware, etc. I did mention this in the license section,

Only when it comes to videos or something that it requires to use the CPU instand of the GPU, but overall works good.

Yes, in terminal the keyboard has all the keys. If you check my video you will see it when I open the terminal.

Yes, workstation is a bit exaggerated. But it is still more useful to me than stock Android on this hardware.

Bookworm was a conservative choice. I haven’t properly tested Trixie yet, so I don’t know. In theory the rootfs should be swappable. Performance is usable, especially compared to stock Android, because there is less background bloat. It’s f

I’d be interested in that. I completely agree, this is not the place to let AI blindly edit kernel code. The useful approach is to use it conservatively: understand the error, compare against downstream sources, propose a small patch, revie

Yes, is swap that expandable RAM.

I also saw the Android 13 version, but I haven’t tested that one, so I don’t know which hardware revision it uses. On the units I tested, the board says: RK3562-v1.0 2024.06.28. This is the listing I used, but it is currently out of stock:

Yes, that’s a fair concern. The tablet is from around 2023, with later revisions around 2024. My point was that this kind of older cheap hardware is already out there in people’s drawers. If a device can boot from SD and the hardware can be

by tech4bot 4mo ago
yes, that is mostly on point. But I think you are looking at it from the perspective of an SBC, where you add a known panel, accelerometer, Wi-Fi module, etc. and already know what components you are integrating. here the hardware is fixed

Likewise, I don’t know if I’m getting a question from an AI or not :) But the answer is fairly simple, on a lot of Rockchip devices I’ve used, if there is no SPI flash or custom boot order, the BootROM checks the SD card first and then fall

I got it from Amazon DE. The listing said it had an RK3562. There are a few different listings with Android 13/14/15/16. I only bought two, one with Android 15 and one with Android 16, and both turned out to be the same hardw

Yes, I used AI to help with the README and wording. But the project itself came from actual testing: opening the device, wiring UART, reading logs, understanding the boot flow, adapting the DTB, and debugging hardware issues. For Wi-Fi, I e

the tablet is cheap and was launched a few years ago, but they still sell it. because it boots from the SD card first, it makes a perfect candidate for this project.

I turned a $80 RK3562 Android tablet into a Debian Linux workstation(github.com)

I reverse-engineered a Doogee U10 (Rockchip RK3562) to boot Debian natively from an SD card. No BSP, no kernel source, no vendor documentation — just a DTB extracted from the stock Android firmware and rebuilt from there. The tablet boots L
