@zhengbicheng 可以了 谢谢

@大法师 👍 👏 下载ing

Does Cool Pi 4B support parallel RGB like the Raspberry Pi 4b? I would love to put Cool Pi 4B board in the PiBoy DMG instead of the Raspberry Pi 4B.

了解，謝謝🙏

@george
上面那个命令末尾添加sync=false 就正常了

@jack_admin

可以使用，感谢。
的确关掉效果没有绑定大核好。

@spartan50416 Thank you very much for your support.

@jack_admin thanks!

@asdf 不客气，具体解决方法可以整理一下，方便后面的小伙伴学习。

@jugg said in 内核更新失败 开机停在logo界面:

@大法师
没刷最新的loader
我又试了一块板 按照更新的步骤 sync 了之后 断电重启 还是不行 驱动那里还是空的

还真的是要sync 不能直接断电重启

@jugg 这个只需要替换内核就可以了。跟之前其它FS的方法是一样的。

@jack_admin 哦

Refer to the following document to provide EDID information and demesg information for inserting and removing HDMI.
https://www.cool-pi.com/topic/296/how-to-drive-non-standard-resolution-hdmi-displays?_=1701475254750

When I plug a desktop monitor in, the edid.bin file is empty and the monitor continues to act as if it has not been plugged in. So I plugged the portable monitor in, and the edid.bin remained empty, even though the monitor woke up and displayed the desktop. Below is the dmesg output from the time I plugged the portable monitor in (I imagine the same i2c read error would be happening with the desktop monitor): [55894.022488] rockchip-vop2 fdd90000.vop: [drm:vop2_crtc_atomic_disable] Crtc atomic disable vp0 [55922.073783] dwhdmi-rockchip fde80000.hdmi: i2c read err!

The currently debugged LCD models are shown in the attachment. The github code has been supported by default. The replacement steps are as follows:

Replace the LCD screen with a touchscreen model Replace the ribbon cable It is necessary to add a touch screen level conversion board

@mez62 可以插上试试

貌似是arch带的编译器版本太高了
用老编译器编的内核可以正常使用panthor

@george that did it, wireguard works now, thanks

I've pulled the latest edk2-rk3588 changes and fixed the display bug: https://github.com/petabyt/edk2-rk3588-genbook

I won't be working on this anymore, especially since the edk2-rk3588 project isn't being actively maintained anymore (the owner has moved on).

Anybody else is welcome to pick up where I left off.

As a reminder: currently it won't boot anything through device tree mode. ACPI works but trackpad and emmc aren't supported yet, so you can't install anything.
