Hello
I have a custom board with the following dts
My zephyr app crashes in bt_enable()
Note that uart0 TX pin 8 is used by gps_vrtc_en but uart0 is not defined. Same crash if I have it explicitly disabled
Unfortunately no logs are available on this board. I call bt_enable explicitly from the shell and the board reboots
Any ideas why?
Thank you
