F28035 Only runs in debug mode

Hi,

I just started out programming the F28035 and have a few issues.

I tried the GPIO toggle example but the code only seems to run when I go to debug mode and click the play button.

After I exit the debug mode and power cycle the DSP, the code doesn't execute.

Also, I tied the SCI echo back example and it doesn't work. No Tx. I tried an oscilloscope on the Tx pin and there are no changes in the logic low level. But I did check that I/O pin separately with a toggle code and the I/O pin works fine, just no serial.

I'm using a Control card in an inverter system and programming it through a JTAG. And I use CCS 5.5

Thanks.
