CC1352P7: Assistance Required for flash BIN file in Bootloader Mode

Tool/software:

Dear Texas Instruments Support Team,

I am using,

CCS Version - 12.7

SDK Version - simplelink_cc13xx_cc26xx_sdk_7_41_00_17

Compiler Version - TI Clang v2.1.2 LTS

I hope this message finds you well.

I am currently working on a BLE Central project based on the CC1352P7 device and have encountered an issue while flashing the .bin file through bootloader (backdoor) mode.

Issue Description is as per below:

• The firmware .bin file works perfectly when flashed via JTAG using Uniflash.

• However, when attempting to flash the same .bin using Flash Programmer 2 (by selecting CC1352P as target device) in bootloader mode, the upload proceeds but fails during verification as per following error:

  CRC verification failed. Mismatch in flash page 87.
  Address 0x000AFFA8: Read 0xFF, expected 0x00.
  Reset target ...
  Reset of target successful.
• I have tried to flash the firmware in bootloader mode using Uniflash (by selecting CC1352P1F3(BOOTLOADER) as target device) refer below attached image for error on uniflash:

I have generated .bin file using following pos-build steps:

${CG_TOOL_ROOT}/bin/tiarmobjcopy -O ihex ${BuildArtifactFileName} ${BuildArtifactFileBaseName}.hex
${PYTHON_PATH} ${PYTHON_SCRIPTS}/hex2bin.py --pad=0xFF --range=0x0:0xAFFFF ${BuildArtifactFileBaseName}.hex ${BuildArtifactFileBaseName}.bin

I have did bootloader settings as per below: (refer below image of .syscfg file for bootloader settings for ble centra project)

Could you please help to confirm:

• Is the .bin file generation logic correct for flashing via bootloader mode?

• Is the range 0x0:0xAFFFF appropriate for the CC1352P7, given the failure at address 0xAFFA8?

• Are there any bootloader constraints regarding .ccfg contents being at the very end of the flash?
  
  

Best Regards,
