F28M35H52C1 control card.
I imported setup_m3 (C:\ti\controlSUITE\device_support\f28m35x\v201\F28M35x_examples_Control\setup_m3) project and burnt into M3 core.
When I burn blinky_c28 (C:\ti\controlSUITE\device_support\f28m35x\v201\F28M35x_examples_Control\blinky\), the LED blinks upon power reset. This means the switch settings on the control card are correct.
I modified typical sysbios example project on C28 core, to add code for blinking LED in the task fxn. I have marked 'Enable boot from FLASH' in boot module.
The code works (LED blinks) on burning but it doesn't run on power reset. The code on C28 core is as follows:
I added F28M35x_GlobalVariableDefs.c, Bhelpuri_F28M35x_Gpio.c, F28M35x_Headers_BIOS.cmd to the project.
