Hi,
We have shared the steps in
Facing the below errors while building the kernel for Javier NX module - #28 by DaneLLL

It should work well if you execute the steps one by one. Please try again.

pthon 3.9 and use xlrd library which call removed getiterator method, replace “getiterator” with iter in “./L4T_bsp/Linux_for_Tegra/bootloader/tegraflash_internal.py” and started working.

Hi,
If your host PC is in Ubuntu 18.04, by default python is linked to 2.7.17. We would suggest use this default version.

No. By default its 3.10. Is there any way to go back?? if so please share the commands
