Dear all,
1) I flash the code through the debugger to my pcb and it is running correctly (just on/off some LEDs).
2) I remove the JTAG+SWD connector, the project still works as expected.
3) I reset it and the system starts working normally. This can be repeated again and again.
4) BUT now I disconnect 3.3 Vcc. Reconnect 3.3V and the application is failed to start. I also try the reset pin, and the application is not running.
5) I use the LDO, i have read through the answer here that by adding a line "CONFIG_BOARD_ENABLE_DCDC=n" to the "prj.conf" file.
But the word "CONFIG_BOARD_ENABLE_DCDC" is not recognized.
I use the visual studio code as an IDE.
SDK: nRF Connect SDK v3.0.0
Toolchain v3.0.1
Can anyone help about how to disable the DCDC function?
Thanks,
Regards,
Carl
What can it be this problem?
Any idea is welcome.
