Part Number: CC2652R
Other Parts Discussed in Thread: UNIFLASH

Hi.

I am using CC2652R Development Kit.

Accidentally I wrote a data at page 43, and then I cannot operate the board with SmartRF Flash programmer.

Error message is :

>Initiate access to target: XDS-L1100CUM using 2-pin cJTAG.

>Debug interface is locked. Aborting action. Only forced mass erase is possible.

Thanks.

Hi,

Did Uniflash recognize your chip (Board) or not?

Thanks,

It can be detected in UniFlash.

Thanks.

Hi,

OK, I sent it to a concerned engineer. He will get back to you ASAP. Please bear with us.

Hi,

Did you try mass erasing by clicking the wrench symbol in the upper right corner (in Flash programmer)?

See this for more information https://e2e.ti.com/support/wireless-connectivity/bluetooth/f/538/t/645591?CC2640R2F-CC2650r2f-locked-bricked-during-programming

Hi,

If you wrote in the last bytes of the CCFG area then it could be permanently locked and have to replace the device.
