How to flash only QSPI on Jetson Orin Nano in JetPack5.1.1/L4T 35.3.1

I would like to know whether we can flash only QSPI on Jetson Orin Nano in JetPack5.1.1/L4T 35.3.1 or not.
You answered that “you could not only flash QSPI of Orin NX” below.

However, there is a guide to flash only QSPI on Jetson Orin series in the following.

$ sudo ./flash.sh --no-systemimg -c bootloader/t186ref/cfg/flash_t234_qspi.xml <board> <rootdev>

https://docs.nvidia.com/jetson/archives/r35.3.1/DeveloperGuide/text/SD/FlashingSupport.html

Could you please tell us if we can flash only QSPI on Jetson Orin Nano in JetPack5.1.1/L4T 35.3.1?

HW : Jetson Orin Nano SOM + custom carrierboard + SSD
SW : JetPack5.1.1/L4T 35.3.1

thanks

flash QSPI with external device nvme.

Hi A_Y,

Yes, you could use the following command to flash QSPI only for Orin Nano.

sudo ./flash.sh -c bootloader/t186ref/cfg/flash_t234_qspi.xml --no-systemimg <board> nvme0n1p1

To KevinFFF-san,

Thank you for the answer. It is clear for us.
