Tablet with RK3562

[MR01]

Hi, im thinking about a new low budget tablet with RK3562 to use with Armbian.

The main points would be to have the console output on the LCD and maybe also the usability of touch for direct input.

 

There is already someone that own a similar product? (tablet with soc RK3562 or just RK)
Im newbie about serial console and debugging, eventually the unlock of bootloader will be a big job or the RK share compatibility in some aspects of booting and more?

I found out that there is already a NPU support on github for the RK3562 (rknpu2 repo)

Thanks for the replies to all.

I've tinkered around with my android Tablet: Umidigi G1 Tab with a Rockchip RK3562.
I compiled my own U-Boot from https://github.com/rockchip-linux/u-boot.
This worked.
Loading u-boot.itb got me an UART console to read stuff.
I switched back to the original U-Boot which restored the device.
Last time I took the wrong U-Boot file (uboot.img - without dtb)

Now I'm stuck.
I found no option to trigger the Maskrom Mode.
Volume- while plugging in worked before for loader mode.
This isn't working.
I still have UART ... but not much to do.
No USB-Controller is found, mmc isn't recognized.
Loadb isn't available

This device has A/B Slots ... I know there is a working configuration in Slot B ... but I have no idea how to force the slot-swap.

Tried: Load rockusb-mode - not possible Load "download" Mode - Crash

Issuing "fastboot usb 0" seems to work, but the device wont get recognized by Windows and Linux.

Hope this can help.
