I have a PCB I made to host a tiny 13A
I have a bizarre situation, I think it is some initialisation problem, or fuses. Please help !!
When I upload my program (assembler in Studio) I get nice 6uA in sleep (8 seconds, woken up by Watchdog.
This is good, the board is powered from LiPo cell.
However, when I cycle power, the multimeter shows 230 uA
I have no idea what reason :( Reset is pulled up to Vcc with 4.7kOhm, no other resistive load, all ports are only woken up when needed. Comparator is off, ADC is used only momentarily, every hour.
There is one button with internal pull-up, connected to the GND, normally open, no current there.
Have you evere experienced such funny behaviour?
