Hello while following the AWS FreeRTOS guide with CC32220SF, I'm having some problems related to Certification files. Here's is the terminal dump:
0 0 [Tmr Svc] Starting Wi-Fi Module ... 1 0 [Tmr Svc] Simple Link task created Device came up in Station mode 2 153 [Tmr Svc] Wi-Fi module initialized. 3 153 [Tmr Svc] Starting key provisioning... 4 153 [Tmr Svc] Write root certificate... 5 252 [Tmr Svc] Write device private key... 6 356 [Tmr Svc] Write device certificate... 7 455 [Tmr Svc] Key provisioning done...

Also, reading here: https://e2e.ti.com/support/wireless-connectivity/wifi/f/968/t/602961, I looked for certificate_sl, but instead found this. 
I suppose it is related to the fact that Certificates are hardcoded?
Anyway, I post here for the given case someone in the TI community has had this issue and could help me with my problem.
