Dead Mobile UPS after Firmware Update
I have UP Squared UPS-APLP4-A20-08128. Installed EP-UPWFMBUPSHAT. Running Ubilinux 4.
I was having a problem where UPS HAT would not finish initialization. I thought maybe the firmware was bad. Tried to update firmware, but got errors about failed to switch to bootloader. I later learned, I need to update i2c device id in susv.cfg. I was now able to get status of UPS HAT. Firmware version was 2.1. I did not think reboot, because I was able to communicate with UPS HAT. I tried updating firmware again per instruction and it updated, but UPS HAT did not reboot. When firmware was updating PSUGN led flashed rapidly. When progress bar in terminal reached 100% all lights on UPS HAT were off. I waited about 5 minutes for board to come back on. Rebooted and UPS HAT never came back. I checked the i2c device ids and it would appear to be using id 6. I can see the RTC 68 but not 0x0F. I tried changing the address buy was unable to select i2c device even after updating in susv.cfg.
I have an second identical system I was able to get working. Just did not update firmware.
Any ideas on how to bring life back into UPS HAT?
Did I brick UPS HAT?
Is an exchange possible?
Thank you in advance for any help,
