Hi all,
I am trying to develop using a custom nrf52 module.This module has no low frequency xtal.
It is possible to configure micropython to run on this specific hardware ?
I'm currently running micropython on Nordic pca10040 but would like to use non-Nordic hardware.

I'm not sure of your use-case, but if you are thinking of running the SD without LF XTAL, you could try running it with RC. This can be achived by adding the

Code: Select all

CFLAGS += -DBLUETOOTH_LFCLK_RC 
in the mpconfigboard.mk For inspiration this is a similar configuration: https://github.com/micropython/micropyt ... igboard.mk
