Hi,
I was at the stage to do current measurment on my nrf52DK for my application, but once I cutted SB9 and powered it back by USB, the 4 leds on the board lighted up and the SoC nrf52832 is no longer working. I found out that when I reconnect SB9 with a jumper on p22, the whole board including the pca10040 stop working. Before I order a replacement, I was wondering if there was a way to fix it or to know what was my mistake to cause such issue?
Thanks for your help!
I don't see how cutting SB9 should lead to any problems, we do this all the time to measure current and then place a jumper on P22 afterwards. Though you may try to call 'nrfjprog --recover' in a command line window to see if it recovers.
Best regards,
Kenneth

Hi Kenneth, I tried sending the recover line and got this error:

Checking voltage on the board at some points, when the jumper on p22 is not connected, I have a 2,89V between Vdd and ground and as soon as I connect the jumper, it goes down at 150mv. Could it be that I created a short somewhere on the board or maybe a faulty hardware?
Thanks for your help so far,
Olivier
Having nothing to lose, I removed the copper plate as my guess was that a bit was making a bridge just underneath and after a while, it now works as it should!
