Hi,
We're experiencing problems booting our application from Flash.
We have a sysBIOS application with IPC/MessageQ on a Concerto dual core.
Booting from flahs doesn't seem to work, and we kinda stuck.
Simple apps (blinky_dc) boot fine, but it seems adding sysBIOS/IPC casuses problems.
To investigate why I decided to boot a TI example appliation from FLASH.
I did read: http://e2e.ti.com/support/embedded/bios/f/355/t/195714.aspx but I have different results.
I can't let the TI example application boot and execute from flash (without CSS)
Could you please check & comment why this fails?
What did I try?
dev board has dipswitches set to boot from flahs (blinky_dc boots from flash correctly)
1) I took the IPC message queue example app for arm + dsp
2) I added code to the ARM part, to control LD3. giving visual indication that the app works.
(mesq get: LD on, mesq put: off -> when test finishes , enable led for ~1 second, by busy wait)
increased
3) tested, works fine in debugger.
4) configured sysbios ARM: boot from flash + boot C28 DSP: added "boot from flash"
5) write with debugger to flash (2x)
6) power cycle board
What did I expect
50 blinks, then 1 second long blink.
What happens
led flashes very fast (estimated by eye 10-20 Hz), led is never shown for 1 second.
It seems to application (an the ARM) keeps booting over and over again.
