DTM serial communication failure in my custom board

[dancpi]

Good afternoon,

I am trying to run the example "direct_test_mode" on a custom board based on a nrf52832.

I have succesfully run the example in two development kits (Laird DVK-BL652), but with the custom board it is impossible to communicate via nRFgo. 

In the custom boards there are some pins connected in order to read/write signals, could some of them interfere with the dtm firmware?

I have tried to debug, but every time i stop in a breakpoint and then resume the execution, it goes to NRF_BREAKPOINT_COND; and breaks. Does it have some timing constraints as the softdevice has?

Am i missing some configuration i should take care in order to make it works? Both the custom board and the development kit have a 32kHz oscillator and just the TX/RX uart lines connected.

Thank you for the support.

Even with the Python script the read fails (not any chars read), while I have managed to run the test for every channel using the development board.

Have you solved it ?
