LAUNCHXL-CC3235SF: Device doesn't run after re-power

Part Number: LAUNCHXL-CC3235SF
Other Parts Discussed in Thread: UNIFLASH

I am using aws subscribe_publish_sample example project. I flash the service pack and keys by UniFlash in development mode. And flash the code by using CCS 10.0.0 debug button(SOP is 010). It will run the code.
But after i click the reset button or only just re-power, it won't run my code just like i doesn't flash it(the file flash by UniFlash still exist).
What should i do to make it work after re-power?

Hey Frank,

CCS allows you to upload and debug your code directly from XIP flash. However to have you code persist after reset you need to use Uniflash to program your host application file. Here are few resources you might find useful:

Uniflash User's Guide: http://www.ti.com/lit/ug/swru469g/swru469g.pdf?ts=1590700617244

Uniflash Basics SimpleLink Academy Course: http://dev.ti.com/tirex/explore/node?node=ABEoqU9o3snoxDcmIpW0EA__fc2e6sr__LATEST

Another option you have, without using Uniflash, is to use the macro __SF_DEBUG__. You can find more information about this macro here (https://e2e.ti.com/support/wireless-connectivity/wifi/f/968/p/639001/2357151#2357151).

Regards,

Paul

For testing, I would link to flash without Uniflash.
I have define __SF_DEBUG__ in main_freertos.c and add ulDebugHeader to linker, but still doesn;t work.
