DeepComputing RISC-V mainboard II not reaching GRUB

Framework Laptop 13 Linux

Which Linux distro are you using?

Ubuntu 24.04

Which kernel are you using?

When using the built-in kernel, everything was working.
I’ve cloned the GitHub - eswincomputing/linux-stable on branch 6.6.18-EIC7X

kernel compiled successfully, it appear at GRUB at first run but it did not work properly. Turns out on the install, it was missing some dtb, when grabbing the dtb from the current kernel, the machine can’t pass the “RISC-V X AI” screen.

Which BIOS version are you using?

This is exactly what I wanna know. (also which bootloader this thing is using)

Additional info:

When plugging the USB-C cable to the UART extension, I can see a file FAIL.TXT with message

`The interface firmware FAILED to reset/halt the target MCU`

I’ve found out that they are using U-boot. Also connecting the UART cable I was able to debug the initialization and enter the u-boot with the serial connection, I will try to flash a img that I download from fml13v03 github of DC-DeepComputing

yeah, with the UART table and picocom plus a pendrive and that fedora image, I was able to run those commands to write:

usb reset
ext4ls usb 0:1 /
es_fs write usb 0:1 sdcard.img nvme 0
