XGECU TL866II overcurrent protection help ?
« on: January 27, 2023, 08:25:40 pm »
I was trying to flash a chip on board that had low 3.3v resistance on it and XGECU TL866II was giving me protection errors.
Now i get the same error on all boards i try to flash.
Anyway to fix that ?

give more specifics ..

if the programmer goes into protection, something is definitely wrong ...  circuit design  etc ... Ie  an eeprom with too many stuff on the same voltage line  etc ...

Power the board up with external supply, then try again.
When doing in-circuit programming, most programmers can´t handle the current flowing because the chip is not the only consumer on the board.
