Flashing Release using UniFlash 6.1.0 Debian and Win10 #27

Closed speedy-scooty closed 3 years ago

speedy-scooty commented 3 years ago

When I verify Release 1.4 (both sniffle_cc26x2r.out and
sniffle_cc2652rb.out) before flashing to my Launchpad CC2652R1F (as auto-detected by UniFlash) I get the following errors, first a red pop-up window stating:

Error! File: C:/Users/acer/Downloads/sniffle_cc26x2r.out: a data verification error occurred, file load failed.

And in the UniFlash Console: [1/8/2021, 11:17:26 PM] [INFO] Cortex_M3_0: GEL Output: Memory Map Initialization Complete. [1/8/2021, 11:17:30 PM] [INFO] Cortex_M4_0: GEL Output: Memory Map Initialization Complete. [1/8/2021, 11:17:32 PM] [ERROR] Cortex_M4_0: File Loader: Verification failed: Values at address 0x00000000 do not match Please verify target memory and memory map.

I only installed UniFlash, no sdk or anything and I think I am using the correct firmware (both sniffle_cc26x2r.out and sniffle_cc2652rb.out) I think. Happens both on latest Debian and Windows. Any tips on how to go further? Maybe taking some of the jumpers of the Launchpad could help, or should I just upload and don't care about verifying?

Thank you!

sniffle_cc26x2r.out is the correct file for your board. I'm not sure why Uniflash is failing to write the code to flash though. Usually the physical connection is fine if Uniflash can detect the CC2652R1F.

Which version of Uniflash are you using? Is the XDS110 programmer firmware up to date? Uniflash will usually tell you if an update for the programmer is available. Also, try using Uniflash GUI to erase the flash, read out flash contents, try flashing Sniffle, then read out the contents again. Maybe that will give some insight.

Hi! I Erased the flash in UniFlash GUI 6.1.0 (Settings & Utilities > Manual Erase > Erase Entire Flash), started a new session, read the target device memory (all FFFFFFFF's) and tried to verify the release image sniffle_cc26x2r.out again. It gave the same error. Instead of bothering, I pressed Load Image (instead of Verify Image) and it loaded the firmware without a hitch it seemed! So, don't verify, LOAD!

Oh, that makes sense. Verify is to make sure the installed code matches the supplied image. Of course the code has to be loaded first :)
