Hello,
I try to make the OMAPL138's DSP core (on LogicPD board ) to run my application when power came on, but i didn't succeed.
First let me show you my code's memory mapping generated by CCS:

I follow flashing instructions at http://processors.wiki.ti.com/index.php/OMAPL138_StarterWare_Booting_And_Flashing .
I type the following command : " sfh_OMAP-L138.exe -flash boot.ais MyapplicationCode.bin -appStartAddr 0x0080E5C0 -appLoadAddr 0x0080E5C0 " and i got this result

After that, when i set the switches (5:8 = 0000 on the EVM) and reset the board, nothing happend because my program was supposed to paly a sound and being detected by the host PC when it is connected via a USB cable.
I also try to use the ti's program "UartHost" and the flashing didn't go forward as you can see below:
Please if you know why the OMAPL138 didn't execute my application after booting, just tell me what to do.
Or just send me a simple "helloworld" example if you have it and which start from CCS and run after flashing.
Thanks a lot for evry help.
