Keystone 1 Security Accelerator

Hi folks,

I have a problem with keystone Security Accelerator (SA) on DSP TMS320c6670: I fail to use data-mode with CCM encryption if packet length is divisible by 32 bytes.

This does not seem to be a problem in my configuration due to SA works fine for me with any other message length. But when packet length is e.g. 32, 64, or 1600, then SA does not send a packet to RX queue at all.

I have now SA LLD release 02.00.00.06. I debugged SA LLD Sa_chanSendData-function command-label with messages of length 32 and 33 bytes. The command labels were identical (except length bytes were changed), and thus I guess also LLD is working fine too.

Do you have idea how to fix this problem?

BR, Ari
