I cannot get my Power Management & UPS Hat to work. When connected to the Raspberry Pi 4 with the battery and power via USB-C, the Raspberry Pi will not boot. L1 is green, L2 is Red. The only way the Raspberry Pi will power on is if I plug USB-C into the USB-C power port on the Raspberry Pi itself.
I did some troubleshooting and did notice that the power hat is not showing up in i2cdetect. For testing to ensure i2c was enabled, I connected a 2 line LCD that is controlled by i2c. It was detected and had an address in i2cdetect.
Does anyone have any suggestions? I also have the 3G/4G<E BASE HAT and it is not detected as having any i2c addresses as well.
