Description Karl Wechsler CLA 2011-08-05 19:20:47 EDT
We are placing the 28x entry point at the very end of FLASH on the 28x device.

Unfortunately, these last few words are reserved for the CSM password.  We can write them once, but then the device is locked and requires special unlock steps.

We did not see this on first Si since the first samples did not have security enabled for the FLASH.

We need to move these entry points somewhere else to avoid this problem.

Workaround is to not boot from FLASH and use CCS to boot both Arm and DSP.

Set the following in your .cfg file:

var Boot = xdc.useModule('ti.catalog.c2800.concertoInit.Boot');
Boot.bootFromFlash = false;
