SWD to recover bricked chip

user114391

Hi! I was wondering if I could use an SWD connection to recover a bricked chip. This chip is on a custom PCB that has pins allocated for SWD.

The chip itself is stuck at a point where it can't initialise BLE advertising so we have not been able to put it into bootloader mode to save it.

To perform the SWD update I was hoping to use something like this: http://embeddedsoftdev.blogspot.com/p/idap-link.html

    Hi, 

    Do you mean to perform the nrfjprog --recover command over SWD? It needs to install the nRF Command Line tool. However, the recover command is used to Erases all user available non-volatile memory and disables the read back protection mechanism if enabled. It would not work as you expect to put the device into bootloader mode. 

    Are you working on DFU? With nRF5 or NCS? 

    Regards,
    Amanda
