JLink error "Failed to power up DAP" after loading the soft device

[John]

Hello,

I am working on a custom development board that is using the nRF52840. After programming the nRF52840 on the board with Soft Device s140_nrf52_7.0.1_softdevice.hex from the NRF5x SDK 16.0.0, I can no longer connect to the chip using a JLink Ultra or a PCA10056 dev board as a pass through debugger. When I attempt to get back to square one using "nrfjprog --recover --log", it errors out with a "Failed to power up DAP" error. I will attach the full log to this question. I had the HW guys replace the nRF52, and the same thing happened. Which leads me to think something outside the chip may be contributing to this problem, but I do not know what it could be. I have 4 other instances of the same custom development board and they work fine. I can program the soft device with nRFConnect, and then our application with IAR and all is well.

Any ideas on further debugging or cause of the problem? These boards are in rather short supply for us right now so if we could get this one working it would be a great help.

Thanks in advance,

John

Hi, so if I understand correctly you replaced the chip on the failing board, and you were able to flash it once, before it died? And the 4 other identical boards are working just fine with the exact same FW?

Can you check that the reset pin is on the failing board is not shortened to ground? If the reset pin was not enabled in the first place, but enabled after the FW programming, I think you will see similar symptoms.

Then to debug further, can you check the voltage on VDD, DEC1 and DEC4 as well as the SWD interface?

Are you using high voltage mode or are the VDD and VDDH pins connected to the same source?

Hi Stian,

To answer your question, the problem was identical with both the initial nrf52840 and the replacement: The chip could be programmed with the Soft Device from nRFConnect, but any further attempt to program, erase, recover etc. ran into the error with the DAP. There are 4 other identical boards that do not show this problem, so I'm pretty sure it's something about this particular board.

I will have the HW guys check the things you suggested and update this when I have he results.

Thank you!

John

Hi Stian,

The HW folks dug into the reset line and it is indeed stuck low. Even after removing every component it is still stuck. They suspect something is wrong under the BGA. The board will be going to our X-Ray machine at some point to check, but you pretty much nailed what the problem was. 

Thanks,

John

Hello,

Do you have some status with this topic? Didi you find any root cause of the problem?

I have the same issues with one of my boards. I am using E01-2G4M04S1B. I had the module flashed and it was working fine. 

I made an erase then flashed the Softdevice 7.0.1 and now is not responding and i get the same Failed to power up DAP error.

Thanks!

[John]

It was indeed a problem with the board. We eventually scrapped it.
