We have a custom carrier board with an NVIDIA Jetson AGX Orin Industrial SOM integrated into it.
Initially, we ported JetPack 5.1.3, and the system operated without any issues. After migrating to JetPack 6.1, we started observing the following message during boot, consistently after each reboot:
SPI-SLV: EPL Handler Failed to send SW-Error report to SMCU!, retrying...
Based on our investigation, this message does not appear to originate from the Linux kernel, and we have not been able to identify its exact source.
Could you please help clarify the following:
-
What is the origin of this message, and what does it indicate?
-
Does it point to a functional issue in the SPI-SLV ↔ SMCU communication path?
-
Are there any known causes or recommended debugging steps for this issue on JetPack/L4T 6.1?
-
Is there a supported method to prevent, suppress, or disable this message if it is expected and does not impact functionality?
Hello @Ahmedrias!
Based on the title and content of your topic, it looks like it may receive better visibility and feedback in a different category. We took the liberty of moving it for you.
If this was an incorrect assessment, please send me a direct message.

According to your picture you have 521 apt packages you could upgrade. Other people have also not updated their Jetsons, but your error
spi-slv: epl handler failed to send sw-error report to smcu~, retrying..
might possibly be solved if there is an updated qspi / bootloader package. You can check and if there is an update you might install it.
sudo apt search nvidia-l4t-bootloader
And I just noticed the Jetson AGX Orin Series Design Guide (including AGX Orin Industrial) was updated on 5/26/26.

Hi Ahmedrias,
It means the SPI slave tried to send a software error report to the SMCU, but the transfer failed, so it is retrying.
On AGX Orin Industrial, this message is usually ignorable if the board has no SMCU and the system is otherwise working normally.
Could you also verify with the latest Jetpack 6.2.2(r36.5)?
Hi KevinFFF,
We would like to upgrade specifically to JetPack 6.1.
In the related discussion, “[r36.4][JP6.1]Constant error message from SPI-SLV on uart,” I understand that it was confirmed this message can be safely ignored and that it is expected to be printed only 10 times.
Could you please confirm whether it is possible to suppress or remove this message in JetPack 6.1?
That message is printed from FSI FW and the source for FSI is not public so that you could not disable them manually in JP6.1.
Please update to the latest Jetpack release(i.e. r36.5) which should include the related fix to suppress them.
