Error messages with se5x when reading id list

Jamier — Fri, 11 Oct 2024 19:30:26 GMT

I am working with a provisioned secure element se050 and I am suddenly getting error messages instead of the id list.

I use these commands and I would normally get an output of a bunch of key ids.

ssscli connect se05x t1oi2c non

ssscli se05x readidlist

But suddenly I am seeing these two error messages on two different chips:

ERROR:cli.cli:invalid load key, '\x00'.
ERROR:cli.cli:'Context' object has no attribute 'session'

ERROR:cli.cli:Ran out of input
ERROR:cli.cli:'Context' object has no attribute 'session'

A power cycle doesn't help.

Does anyone know what's going on?

The devices these chips have been installed on have been undergoing stress and environmental testing -40C to +65C.

Thanks.

Hi @Jamier ,

Which variant of SE05x was used in your test? Have you tried to rebuild sssapisw within the MW with the verbose log level? It would be very helpful to have the log during this issue.

Have a great day,
Kan

Thanks for the suggestion.

I ended up getting it working by reprogramming my BSP. I didn't try the verbose log as I didn't have the time to do the setup for that. I suspect the problem was caused by corrupted files and not by anything to do with the chip or the i2c communication.
