I flashed the output .out and .hex file with CCS and Uniflash and had following results:
CCS + out file: SW runs
CCS + hex file: SW does not run
Uniflash + out file: SW does not run
Uniflash + hex file: SW does not run
Could you please explain the reason of different results here and where should I do to get SW run using HEX file with CCS and Uniflash?

Quy
