Other Parts Discussed in Thread: UNIFLASH

I am using CC2745R10 then i am not able to chip erase it from the uniflash tool (V 9.1.0.5175) do there are any other option to chip erase or erase the previous program, this is because i have flashed a software which is doing reset regularly very fast so i am unable to flash the new program or debug it so i want to erase that previous code.

Hello,

You can do a chip-erase via CCS.

Via Code Composer Studio: (+) LP-EM-CC2745R10-Q1: Chip Erase not possible in UNIFLASH - Arm-based microcontrollers forum - Arm-based microcontrollers - TI E2E support forums

Via CCS Theia:

1. Go to the project in CCS Theia, and open the targetConfigs folder, right-click the CC2745R10.ccxml file and select Start Project-less Debug:

2. Once the debug session has started, right click on the Cortex_M33_0 and click on Show All Cores:

3. Highlight, but do not connect, the CS_DAP_0 core.

4. Go to Scripts --> CC23xx --> Chip Erase

5. It is successful when you get a CS_DAP_0: Chip Erase completed with return code: 0

Please note that if your device is constantly resetting, you may need to try this multiple times before the chip erase is successful.

Best,

Nima Behmanesh
