Cannot connect or recover nrd51 dk

eozkucur

Hi,

I have 3 nRF51 DK pca10028 v1.1.0 I compiled and run power profiling example and after that I cannot flash or connect to the devices (tested in all three of them).

In nRFgo Studio, the recover page is displayed, but the recover button is disabled.

The JLink Commander outputs "WARNING: RESET (pin 15) high, but should be low. Please check target hardware." several times.

I can enter the bootloader mode, install the bin file and power reset, after that nRFgo studio prompts to update the firmware, but after the update the problem still persists.

I included a screenshot of the problem.

Edit: I solved the problem. Previously I cut the SB9 line to measure current output. And I got these problems when I tried to connect the kit without a multimeter. I solved the problem connecting P22 pins together.
