A603 usb ports not working when flashed jetson nano Orin with nvidia sdk to memory card

Hi, I have successfully flashed jetson nano Orion 8gb board with nvidia sdk, once I replace the Carrie board to a603 from the original jetson board. The usb on ports are not working but the hdmi is working and it boots up fine. Is there a way to enable them.

And my 2nd question is can I directly flash to sd card instead of nvme procedure that’s shown in the wiki. If so what is the procedure and commands used for it.

Thank you.

did you figure it out? USB does not work for me with A603 + orin nano, JP6.0

Download the DTB files specific to the A603 carrier board from the manufacturer’s website or wiki.
Copy the DTB file to the Jetson Nano’s /boot directory or the location specified by your Linux distribution.
Modify the boot configuration to use the new DTB:

sudo nano /boot/extlinux/extlinux.conf

Replace the FDT line with the path to the A603-compatible DTB file:

FDT /boot/<a603-dtb-file>.dtb

Please strictly follow the wiki instructions to operate. Different carrier boards need different flashing packs, so if you move a module from one carrier board to another, it will need to be reflashed.

Thanks, after unzipping, how should I copy bootloader, kernel, rootfs in A603-JP6.0.zip to Linux_for_Tegra folder, there is some permission issue to copy to rootfs
