Fanstel BT840 programming
Hi, currently, I am trying to migrate from Redbear Blenano2(NRF52832) to Fanstel Bt840(NRF52840). I am able to compile a program (using platformio&MBED) and upload it to the board, but it does nothing. I tried debugging it, and it seems to hang on
Wait for the external oscillator to start up. while (NRF_CLOCK->EVENTS_LFCLKSTARTED == 0) { Do nothing. }
If I upload it to my NRF52840_DK, everything works as expected. the target I am using is the nrf52840_dk, but it should work with every 840 processor, am I right?
any Ideas on why it hangs there?
EDIT: I just found out the fanstel chip does not have the LFCLOCK crystal on board, I think thats the issue.
