| Repair Help for APC UPS BR1500G - F06 error (FIXED!!) |

| fmashockie:
Thank you both for your quick responses! So I guess when you say read siz, I should change size (see photo) from 0x400 to 0x200000 (or 0xffffff as darkspr1te said)?? Sorry this is all completely new to me so thank you bearing with me! |
| DavidAlfa:
Exactly. Do that when reading it. About VDD and PB14 shorted together... double check everything connected to it, suggests some external voltage spike fried the esd diode! |
| fmashockie:
Thank you so much DavidAlfa! I will give it another go as soon as I get in to the lab today. I let y'all know how I make out! And I did verify that the VDD to PB14 short is on the micro. That being said, doesn't rule out there's some issue on the board I haven't found that could cause it to happen again :scared: Will report back later! |

Well everyone I am pleased to say that this APC UPS BR1500G is fixed! It put up quite a fight! :box: So changing the read size to 0x20000 allowed me to flash the micro correctly! Need to learn to read hexadecimal lol. Can't thank you guys enough for all the help. Could not have fixed it without everyone's input! Final video to the series for those interested in watching :-DD |

Awesome, glad to see you fixed it in the end!! A dead GPIO pin huh - who would've thought of that when presented with an "AVR relay weld fault"! Repairs certainly are a great way to learn: IMO there is no better way to learn about electronics than to solve real problems like this, and see first-hand all the weird stuff that actually happens in circuits. Plus, who doesn't love a good mystery! |
