Between decode and encode we are reloading the icont 1 and 2 code with a bootloader. This runs on M3 out of sl2 memory as described in publication SWPU140 page 28. After the new code has been loaded into the ITCM, DTCM and sl2 the PRCM is used to issue a reset via the M3. However, the iconts do not start to execute code until the CCS "Target run" is manually issued (although it works fine on the simulator, not on the EVM). I am missing a step that must be required to restart the iconts running. In the document, it states that icont1 is waiting for a mailbox interrupt. However, I am not clear how this is issued or whether this is actually the missing command. I guess I need to understand what is is that "Target run" does.
