Hi,

Can you please provide a screenshot of what you're referring to within Uniflash?

Thanks,
Toby

Got it. On my end, it is showing MD5 instead (using version Uniflash version 9.2.0.5300).

Which version of Uniflash are you using?

Can you try opening an .hex file generated from an out-of-box SDK example?

I've uploaded one here for reference: https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/538/empty_5F00_LP_5F00_EM_5F00_CC2340R5_5F00_freertos_5F00_ticlang.hex

I could not find an option in Uniflash CLI (dslite) for that.

This post shows a way to do it in Python, it could be adjusted to print out specifically the calculated CRC or be read from the generated/updated file: (+) CC2340R5: CRC bytes in CC2340's CCFG - Bluetooth forum - Bluetooth®︎ - TI E2E support forums
