Hi everyone ! I am having trouble trying to flash a custom firmware to a nrf52840 board connected to another custom board using P19 debug out I am flashing the code directly using the IMCU USB port on the nrf52840 board. SB19 is soldered to the on-board J-Link to route the signal to the Debug OUT port Hope you guys can help me solve this problem as it has taken me too long ! Thanks averyone, have a nice day !

Can you share som diagram or image of your setup `?

Also have you had the custom board review?

Hi Jonathan !
Pin connection diagram from P19 nrf52840 via DEBUG board to customboard J2 :

Pin 1 VREF (P19) -> pin1 Vin->Vin=2.8V (J2)
Pin 2: SWDIO (P19) -> pin2 -> pin2: SWDIO (J2)
Pin 4: SWDCLK (P19) -> pin3 -> pin4: SWCLK (J2)
Pin5: GND (P19) -> pin 6 -> Pin 5: GND (J2)
Pin 10: RESET (P19) -> pin4 -> pin3: NRST_nRF (J2)

My custom board uses nrf52840 chip and has J2 port to communicate with nrf52840 board

P19(nRF52840-DK) -> Board DEBUG -> J2 (Custom board)
and I use TC2030-MCP-NL wire to communicate from DEBUG board to my Custom board

[JONATHAN LL]

Make sure the voltage on the Custom board is the same as the voltage on the programmer DK, a mismatch in the voltage here can cause this issue. 

So make sure that the two boards operate at the same voltage.

Jonathan

Hi Jonathan !

I'm having trouble with DEBUG and it doesn't show LOG on RTT after i flash successfully using P20 nRF52840-DK

Can you help me fix it?
Thanks !

nRF52840DK (P20) ---> Custom board
-------------------------------------------------
VDD_nRF(P20) → SWD_SEL(P20) 
VDD_nRF(P20) → Vin custom board 
SWDIO/CLK → SWDIO/CLK custom board 
GND → GND custom boardCustom board with separate power supply

[JONATHAN LL]

Do you have a pin\LED on your custom board that you can toggle?

Its often best to start simple with custom HW to make sure things are configured correctly. 

You can also use the DK as a UART\Serial adapter. 

Also are you building for the custom board or ar you using the board file of the DK when you make the project?
Does it run ok on the DK if you test the app there?

Jonathan
