I was trying to flash my Jetson orin NX with custom carrier board. I was not able to flash the APP image from my laptop.

[ 13]: l4t_flash_from_kernel: Warning: skip writing esp_alt partition as no image is specified

Flash failure
Cleaning up...

Changed the partition layout xml and flash was successful but when tried to boot it’s showing rootfs mount fail in uart log.

But I was able to successfully flash and boot from my friends laptop using the same sdk and flashing command. The laptop configurations were identical also.

Hi,

Could you provide your flashing commands for us to review?

Thanks

I used this command:

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 p3509-a02+p3767-0000 external

I don’t think this is issue with flashing command, I was able to flash with the same command from my friends laptop.
Is this something related with permission related issues since I am getting this error,

l4t_flash_from_kernel: APP image /mnt/external/ is not found !!!

When I tried from friend laptop this came:

@DavidDDD

I think my problem is with this

Warning: skip writing esp_alt partition as no image is specified
/lib/ld-linux-aarch64.so.1: No such file or directory
Copying APP image into  /Linux_for_Tegra/tools/kernel_flash/images/external/.raw
mount: /tmp/ci-EfKJo54U0i: failed to setup loop device for /Linux_for_Tegra/bootloader/.raw.

But I was able to find the /lib/ld-linux-aarch64.so.1 file in the rootfs

Hi,

Is the issue solved?
If not, please attach the whole flashing log and the serial console log for us to review.
About serial console log, you could refer to below link
