Recent Raspberry Pi firmware provides a mailbox property to detect under-voltage conditions. Here is the current definition. The u32 value returned by the firmware is divided into 2 parts: - lower 16-bits are the live value - upper 16-bits are the history or sticky value Bits: 0: undervoltage 1: arm frequency capped 2: currently throttled 16: undervoltage has occurred 17: arm frequency capped has occurred 18: throttling has occurred Signed-off-by: Stefan Wahren <stefan.wahren@i2se.com> --- include/soc/bcm2835/raspberrypi-firmware.h | 1 + 1 file changed, 1 insertion(+)
