Cannot reset or erase nRF54L15 DK

[garrettb]

Hi

 

I have two nRF54L15 DK boards (PCA10156).

Both are behaving the same way right now.

.......................................

ONE: Using nRFConnect in VSCode, I cannot flash the device:

History:

.......................................

I think I tried to flash the DK with a project I was working on. It originally was for a different board file, so I created a build config for the nRF54L15DK, then removed a lot of the application code so that it would build. Then I flash ed the DK, and the device seemed to run  - I was able run a BLE scan and see it. I can only thin that there was something wrong with the application that messed things up.

Then the next time (I think), it wouldn’t flash - I think I was trying to run it in debug mode.

I am guessing I eventually tried the 2nd DK - which probably worked the first time, although I am guessing.

SO I then created a new project from the BLE Peripheral UART sample, for the nRF54L15DK.

All the build configs above were for SDK/Toolchain 2.9.2

Question: How can I recover these devices?

Thanks

Hi

Both device have been successfully recovered.

I reverted to the older nrfjproj utility.
I don’t know why this worked and nrfutils wouldn't.

This is how I recovered both devices

First, I got the serial number:

nrfjprog --ids

Then I did the following.

nrfjprog --recover --snr 105776****
nrfjprog --eraseall --snr 105776****
nrfjprog --reset --snr 105776****

Note: Sometimes the recover script would take about 30 seconds to complete.

Hi Garrett,

Maybe it's because the OBD firmware is not up to date. You might be able to recover the board, by opening Jlink Commander, the OBD FW might be in bootloader mode, and then opening JLink Commander might give you a prompt to program the OBD FW again.

ok, maybe that's what it was :)
