CC3X00EMBEDDEDPROG: Code changes not reflecting after flashing - CC3501ENJARSHR chipset with CCS 20.4.1 tool

Part Number: CC3X00EMBEDDEDPROG
Other Parts Discussed in Thread: SYSCONFIG

Hi TI Team,

I am working on the CC3501ENJARSHR chipset using CCS 20.4.1 development tool and simplelink_wifi_sdk_9_22_00_15 SDK.

I am using the "at_commands" example code. I built the code and loaded it onto the EVK board. After flashing and restarting the board, I see the debug message shown in the attached image on the debug UART.

To troubleshoot, I commented out the debug message "Enter AT Command:" in the code, rebuilt the project, and flashed it again to the EVK board. However, I am still seeing the same debug message on the UART, indicating that my code changes are not taking effect.

What could be causing this issue? It seems that any modifications I make to the code are not reflected after loading onto the EVK.

Additional Details:

  • Chipset: CC3501ENJARSHR

  • CCS Version: 20.4.1

  • SDK Version: simplelink_wifi_sdk_9_22_00_15

  • Example code: at_commands

I have attached the screenshot showing the debug UART output for reference.

Please let me know what steps I should take to ensure my code changes are properly applied.

Thank you.

Regards,
Venkata Kishore

    Hi Venkata,

    Can you please confirm what version of sysconfig you are using? Simplelink_wifi_sdk_9_22_xx_xx from my experience requires sysconfig version 1.26.1 or greater as a dependency. You can confirm this by right clicking your project -> Properties -> Dependencies, and seeing your Sysconfig version (see my dependencies below). You can click on sysconfig and click on the marker if you have an older dependency listed to update it to the newest version.

    After doing this, I was able to use the at_commands example while commenting out the "Enter AT Commands" line and I saw the update reflected in my terminal.

    Please let me know if this resolves your issue!

    Best Regards,
