unable to find or open the jLinkARM dll

GeekGeek1192

Hello,

             I am using PCA10040 DK for programming my custom board which is having the NRF52832 controller. Until yesterday afternoon, I was able to program my board using NRFgoStudio.

Suddenly NRF52 dev board stops detecting in the go studio. I had removed nrf command line, nrfgo studio, segger embedded studio, jlink drier and reinstalled all did not worked.

Some time I get the below error.

also I am trying to use the nrf connect to program another device using nrf52 dk but could not able to. If I am programing on chip controller using NRF connect programmer its detecting in select device. When I am trying to program another controller by removing P22 pin from PCA10040, it's not getting detected in NRF connect programmer.

any help will highly appreciated!!!

    Have you shorted the P22 header? YOu should be able to find the DK under "Select Device" on the left hand side. Please also note that the voltage supported by external debugging is 3V. Make sure that your DK and external board is powered correctly.

    Best regards,

    Simon
