board not working

[katrindqaws]

I have printed and assembled this circuit. The board is programmed with the help of a development board, but it doesn’t work. What could be the problem?

my code (led toggling) works on DK board properly but not works on this board

Hi,

You can check fw that config pin reset is enable or not?

If yes, please make sure P0.18 is in high state or chip will always reset.

You can go into debug mode and check there has error code or not.
