Issue after cutting sb9 for current measurments

[Olivier]

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 have got the same issue.

It is very strange, because J22 connected in parallel with SB9 and it is a power line. ???

Closing this case, since it's 5 years old. But a description here:
