I am using the following command to flash the SD card ( keeping the board in recovery mode )

-c tools/kernel_flash/flash_l4t_external.xml -p “-c bootloader/generic/cfg/flash_t234_qspi.xml”

But Ia m getting the error message

mmcblk0p1 is not supported.

( I am using 64GB SD card ).

Please suggest what is going wrong here.

This is for 36.2.
For 35.x, you should use

sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device mmcblk1p1 \
  -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
