PinebookPRO black screen with newer mainline kernels

What is happening?

• I build an image with latest kernel-5.10.2 and aarch64 root

git clone https://github.com/void-linux/void-mklive
cd void-mklive
make
./mkrootfs.sh aarch64
./mkplatformfs.sh pinebookpro <base-tarballl>
./mkimage.sh -B 512M <rootfs-tarball>

• I flash the image to an SD dd if=<image> of=<disk>
• I try to boot the SD on Pinebook PRO
• The Screen Remains Black, the LED switch from yellow to green.

Expected Behaviour

The system boots correctly

Troubleshooting

I tried different microSD brands.
ARCH Linux image is booting correctly.

I do not imagine you have a serial adapter for the PBP? Are you using dracut or no initramfs (the mmc indexes may have swapped again)?

[thypon]

No serial adapter here with me. No change to the base image, not even the SD one is booting. When It is booting from the eMMC the led remains yellow, while on the SD it turns green. This usually means the kernel has booted.

@CameronNemo I think the title may be misleading, I'm not using a custom mainline kernel, I'm using the one included in void, pinebookpro-kernel. pinebookpro-kernel is the mainline one since 5.9.x, with minor patches. It was a completely separated tree before.

The problem is that I cannot even create a working SD card from void-mklive with latest rootfs, at the moment.

[CameronNemo]

@thypon indeed the new kernel we have uses more modules it seems, conflicting with the initramfs-less image created by this repo. you could try to find out which Ms need to be Ys in the kernel config, or just add dracut to the platformfs.

[thypon]

I will try with dracut, thanks. It may be time to add dracut as pinebook-base package, anyway.

[thypon]

It's working good with dracut.

[ericonr]

I believe this has been fixed? Initramfs could be documented as a requirement, but that goes in void-docs.

[CameronNemo]

I would consider this fixed if building the image from this repo without any additional packages produced something functional. Right now the user has to manually specify dracut as an additional package. That is the bug from my POV.
