fall back to LDO if DCDC not work

[leox]

Hi,

can nRF52/nRF53 automatically fall back to LDO mode if DCDC enabled in firmware but with bad inductor connection on PCB?

Could re-flash the firmware to disable DCDC but need to access to the hardware. For in field devices in case inductor or inductor connections failed (DCDC enabled) due to vibration or other physical damage, is there any fall back logic could be built to the firmware to fall back LDO.

for example:  firmware able to detect a bad DCDC circuit, then disable DCDC and continue to operate without DCDC.

Hi Leo, 

I don't think the firmware can do that.
