Meet a CHANSEL_NOMATCH issue when driving imx577 on Jetson Orin Nano

[EmondCai]

Hi ShaneCCC, I find the root cause why the dmabuf_fd -1 issue happens！

Since I was using a xavier nx carrier board to boot Orin Nx, I can’t flash through GUI directly and I have to set cvb_eeprom_read_size to zero and flash through:

sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1
-c tools/kernel_flash/flash_l4t_external.xml -p “-c bootloader/t186ref/cfg/flash_t234_qspi.xml”
–showlogs --network usb0 jetson-orin-nano-devkit internal
So based on a zero cvb_eeprom_read_size I can not solve the issue what ever I do.

After I got a Orin nano p3768 carrier board, the issue still remains because I didn’t reflash the jetpack. And after I flash the Orin nano through gui, then my imx577 works.

So does it mean I can never drive my imx577 on a xaver nx board which doesn’t have a eeprom？If I can，is there any method I can do this since our product is based on xavier nx carrier board？

Thanks

It could be device tree incorrect cause it.
You can make the device tree correct to make it right without EEPROM.

Thank you for your reply ShaneCCC!

@ShaneCCC

It could be device tree incorrect cause it.

What is the incorrect stands for ?

Like orin nano 8g must use a tegra234-p3767-0003-p3768-0000-a0.dtb , but can not use a tegra234-p3767-0001-p3768-0000-a0?

You can dump the device tree by below command to compare the working and failed.

sudo dtc -I fs -O dts -o extracted_proc.dts /proc/device-tree
