I have a custom board with an ATTINY1616 that I flash by using an Arduino Nano with jtag2updi. Flashing works perfectly fine and the code is executed immediately after. But after flashing the chip needs 1.35mA more than it normally does, like something is leaking. If I perform a hard reset this additional current is gone and everything is ok. Anyone has an idea where this is coming from and how to prevent it? I need to flash the software while the chip is connected to a battery that I can't disconnect, so no hard reset possible.
