When using ISP direct connection( CLK, CMD, Dat0, GND, VCC and VCCQ pins) must a battery be connected to the device or VCC and VCCQ is supplied from UFI via ISP adaptor? Thanks for the reply
Jane Hello, Yes, VCC and VCCQ is supplied by internal regulator from UFI Box.
Thanks for the reply. I measured the VCC and VCCQ on ISP adaptor and there was only about 0.5V of VCCQ. VCC was higher - about 3V. So I am not sure if it was my mainboard problem ( I wanted to repair) or a UFI adaptor problem or any other problem. Should there be proper voltages also in a case that CLK, CMD or DAT0 are disconnected from a mainboard? Or must be connected all pins because UFI box tests connections?
