OCSD_ERR_TEST_SS_TO_DECODER error occured when I get trace from my custom CSAL #20

I created my custom CSAL library to add support for Jetson TX2 board and it works almost correctly(Fetching cstrace.bin succeeds). However when executing trc_pkt_lister in Jetson TX2 snapshot directory, trc_pkt_lister says as follows.

Trace Packet Lister: CS Decode library testing

Test Command Line:-
trc_pkt_lister   --decode

Is this error caused by the lack of implementation of my CSAL registration function? or the lack of support in OpenCSD library?

Hi,

The current library has a mapping between core name e.g. Cortex-A53 and the architecture implemented. If you have a core name that is not recognised then this will result in the above error.

Either use a supported core name that matches the architecture of the core you are using, or add the name to the mapping function in the library.

A future version of the library may add generic architecture mapping to the library.

Thank you for replying me! I just fixed the core name as Cortex-A57 in my .ini file and it finally works! I really appreciate your advice, thank you!
