XGECU TL866II overcurrent protection help ?
Posted by tonycstech on 27 Jan, 2023 20:25
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.

Did you figure out a way to bypass it? I'm trying to do in circuit programming and it's risky desoldering the EEPROM.
