"local variable 'bpmp_dtb' referenced before assignment" error in /tegraflash_impl_t234.py

[shah2]

I’m using a Jetson Orin Nano devkit, I’m trying to configure the pinmux using new .dtsi files, but when I try to flash I receive this error:

Traceback (most recent call last):
  File "/Linux_for_Tegra/bootloader/tegraflash_impl_t234.py", line 1401, in tegraflash_update_bpmp_dtb
    if bpmp_dtb == None and bpmp_dtb_in_layout == None:
UnboundLocalError: local variable 'bpmp_dtb' referenced before assignment

I’ve included the output log. I’m following this guide: https://docs.nvidia.com/jetson/archives/r35.4.1/DeveloperGuide/text/HR/JetsonModuleAdaptationAndBringUp/JetsonOrinNxNanoSeries.html#generating-the-pinmux-dtsi-files

If anyone has any guidance on resolving this issue, that would be appreciated.

Hi,

It looks like your flash command is wrong.

Please directly copy from this document.

https://docs.nvidia.com/jetson/archives/r35.4.1/DeveloperGuide/text/IN/QuickStart.html#to-flash-the-jetson-developer-kit-operating-software

For example,

this is what you use

But this is actually what our document uses:

The correct command is passing a string “-c xxxxx” to the -p parameter. But your command is passing nothing to -p and then give -c another parameter.

Hi Wayne,

Thanks for looking into this. I do include the quotation marks in my flash command, it is just removed in the in the output log. I directly copied the command you linked, but get the same result. I have included the updated log and included the input command at the top.

Did you ever customize anything else inside the Linux_for_Tegra BSP directory?
