Hi

i used nrf52833 dev kit for developement, now i have custom board with NRF52833.

How to connect it with vs code to upload my firmware?

Hello,

To program a custom board, you will need to use an external debugger or any of the DK.. You will need to connect your custom board to the Debug Out port of the DK and then program.See here: https://docs.nordicsemi.com/bundle/ug_nrf52840_dk/page/UG/dk/hw_debug_out.html  There are multiple tickets in Devzone that you can refer like this one: Programming a custom external board using nRF52832 dk 

You could also refer this to know more about adding support for custom board: Lesson 3 - Adding custom board support - Nordic Developer Academy  and https://webinarplatform.nordicsemi.com/adding-custom-board-support-in-nrf-4

Hello,

Does your board have a debugger.? a debugger is necessary for the board to be detected.

BUT how to read the serial in custom board?

i uploaded the basic hello world program in my custom board.i found 2 ports in vs code,COM0 AND COM1.

Hello,

For custom boards, you might need to use RTT to read the serial as discussed here:  RE: VCOM to external board on DEBUG OUT  Try adding the following in prj.conf to use RTT:

CONFIG_USE_SEGGER_RTT=y

CONFIG_RTT_CONSOLE=y

CONFIG_UART_CONSOLE=n
