F28335 eCAN - wrong MSGID in incoming mailbox

Just wanted to get some more clarity on your project. So u must be receiving data only in MBOX31 right?

Function names seem to be confusing. The function void cana_dev_init_send_mailboxes() configures mailboxes 0-15 for receive operation and the other one configures the mailbox for transmit direction. 

So that means you must always be reciving data in MBOX15 and not MBOX31 right?

I have exchanged functions names... sorry! Anyway, mailboxes 0:15 receive, mailboxes 16:31 send. So the first message I receive is written in mailbox 15.

Try keeping a breakpoint in the pop function, inside the for loop and first check if the msg id is updated in the mailbox register MBOX15.Msgid field.
