Dear All

I successfully compiled yocto project with core-minimal-image configuration and yocto deployed an core-image-minimal-rock960-rk3399-gpt.img then I burned this img to a sdcard, and tried for booting from it.

But i get below error message.

Can you share the full kernel log (e.g. via pastebin)?

Changing UART Baudrate to 115200
#4

From this topic I understand you changed the speed to fiq debug speed to 115200: Changing UART Baudrate to 115200, I suppose (no device-tree doc) it modifies the tty max speed and leads to this issue.

From your log I see:

Retrieving file: /extlinux/extlinux.conf

I think you have to edit /extlinux/extlinux.conf and change console=ttyFIQ0,1500000n8 to console=ttyFIQ0,115200n8.

then not sure the device tree change is even requested.
