Flash ext4 rootfs with l4d_initrd_flash

Hi, I’m using this command to flash:

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 internal

Is it possible to, somehow, flash a ext4 rootfs directory I have?

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

I don’t know what you mean.
What is your ext4 rootfs directory?
