Hex file update not working on custom board

[joshi]

Hi,

I have successfully detected my custom board (nrf52832 chip  )  with nrf 52dk board and program it with blinky hex file given in SDK 15 version and works.

Now, i update the blinky file with correct pin number  setting on GPIO pin and it works fine with 52 dk board but when i try to program my custom board with 52dk with SWD protocol it is  not working.

I realize that Hex file folder never update with new GPIO setting , only i manage to update the debug and release but if i try to upload that Hex file it dose not work.

well any help is appreciated.

thanks

i am programing BLE blinky app blinky which advertise. yes, the same code i am trying on custom board works on nrf52DK which has LFRC crystal activated as mentioned on previous post. yes device is advertising and when i try to connect i manage to connect once and it works but after that i can not connect.no i have not try sniffer yet.

i then try to make another board with same component but doing the same thing. i am confused what to do now.

i am using this crystal 

7M-32.000MAHV-T. 

i also check the flag method to check if HF crystal is working or not but always return 0 so now HF crystal is not working and i do not have frequency generator. crystal connection are good.

well any help is appreciated.

thanks

Hello Joshi,

I am no HW expert. I suggest that you create a new ticket, requesting a layout review, where you mention that you have issues with the HFXTAL. Attach the PCB layout and the name of the components you use, and the capacitors that are attached between the XTAL and the nRF.
