CC2642R: Temp file in CC2642 generated memory map

Shuyang Zhong

Part Number: CC2642R

A customer found that a file under C:\Users\<username>\AppData\Local\Temp takes ~5k of memory in the map file generated by simple_peripheral_CC26x2R1_LAUNCHXL_tirtos_ccs:

I did a little research following this link and found this file can be opened by armofd.exe, it show information as below in armofd:

Would you please help explain what is this file and why it takes memory of CC2642? Is it possible to stop this file to be generated in order to save the memory of the device?

Please find the temp file and the map file as attached.

Hi Shuyang,

I am unfamiliar with the temp file that you are observing. I compiled an unmodified simple_peripheral project and was unable to find it in my map file (see attached). Is this occurring on an unmodified example? Can you share the SDK being used?

Best Regards,

Hi Jan,

Yes, it seemed to be a compiler optimization behavior. Thanks for the support!
