Hello all I have a chinese board with RK3188 and I tried to build and use this kernel with Radxa Rock device tree. Unfortunately the boot process stops after a few seconds and it doesn't go on. Here is the serial

In addition mainline kernel from Torvalds boots, however it does not contain board specific drivers Thank you all

peppelinux commented 3 years ago

Got it to work here: https://github.com/peppelinux/Radxa-Rock-RK3188/blob/master/README.md

now I'm compiling rockchip-linux 4.4 instead of linux-stable 5.8.7, further updates on that repository. Don't know why you're encourring in that, I've added init= parameter in boot arguments, I can see systemd starting properly

peppelinux commented 3 years ago

using vanilla kernel 5.8.7 I can get a working prompt instead https://github.com/peppelinux/Radxa-Rock-RK3188/blob/master/batrebox_rk3188_serial.log

my kernel configuration is here: https://github.com/peppelinux/Radxa-Rock-RK3188/blob/master/linux-5.8.7.config

you can also read the README with my build instruction.
