How to set crystal to Clock to RC in Adafruit Feather nrf52832 bootloader

[Girum]

Hi!

I'm using an generica nrf52 board to flash adafruit nef52832 bootloader and then flash my arduino bluefruit code.

One board it goes ok, because flashing previous SoftDevice, the board has an 32k Crystal Oscillator.

The another board does not have this oscillator. If I flash the softDevice (with RC oscillator) it goes ok, but when flash the adrafruit bootloader and next the bluefruit code it not works (only works with BlePeripheral code)

There's a way to generate adrafruti nrf52832 feather bootloader with RC oscillator, instead with the external 32k?

If yes, how?

Did it!
When generate the ino sketech, goes to:

Arduino15/packages/adafruit/hardware/nrf52/1.4.0/variants/feather_nef52832/variant.h

Change:

#define USE_LFXO
// define USE_LFRC

to:

// define USE_LFXO
# define USE_LFRC

To use internal oscillator instead of 32.768 external xtal.

Then flash another time the bootloader, an then flash the .hex sketch file
