Troubleshooting: 1# If your mac model is not on our list, or have different debug port:
Look on the board for a chip that looks like this, or an empty connector that looks like one of this two.
If is the chip, you have to use the SOIC 8 clam provided and place it with the red wire over the pin no1 of the chip.
If is the small debug port, use Adaptor no1, the red color one, and if upon insertion the red light on HDBOX SPI adaptor does not light when the logic board have power, then rotate the adaoptor 180degree
If is the big debug port, first use the adaptor 2, the blue color one, and if the red led does not light up rotate it 180 degree. If the red light still not light, then try use adaptor no3, the yellow color one in both positions.
2# Red light pass, but Detect SPI chip returns either “00 FF FF FF (Not Connected)” or “00 00 00 00 (Not Connected)”
3# Detect SPI returns good id, but read spi chip returns empty image (0xFF)
This means that mac computer still retain ownership of the SPI chip and different power states have to be tried until access to the chip is granted to our interface.
Different power modes can be tried by having battery connected or removed, charger plugged or not, computer on or not, different macs will work in different modes so you have to try the one that work for your mac.
4# Read was ok, but I have issues at writing to the chip
This means that while our interface was able to access the SPI chip in read only mode, the Write Protect line is protected by the mac. To fix this issue, please try different power state until mac release full control of the SPI chip.
