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

hi

 well i manage to program the board and as u ask me i am using segger embedded studio.

but now BLE is not working.

when i scan on nrf ios app i can see my custom board name but can not connect.

interesting thing is i manage to connect once with my board to nrf app on IOS and blinky BLE program works but after that i can not connect it.

i was reading the last post and i found one has the same issue according to that i turn on the internal LFRC oscillator but when i am checking that my HFCLK ( external 32MH) crystal is working or not but code stuck. i do not have optional or extra crystal on my custom board.

my soldering connections are good i checked for crystal 32 MH high frequency.

well any help is appreciated.

thanks

What did you program om the custom board? does the same project work on the DK? Is the device advertising? What happens when you try to connect? Have you tried to sniff the connection establishment using nRF Sniffer?
