Troubleshooting Manual

0x00: Severe fever/abnormal power supply

Solution: Measure the resistance of each power supply to ground, check whether there is a short circuit, and check whether the active crystal oscillator is used incorrectly. R16 and R17 need to be swapped before the " 2022.06.27 Ver0.4 " version.

0x01: The crystal oscillator does not vibrate

Solution: Congratulations~ There is a high probability that H5 is not posted properly, please rework and plant again.

0x02: DRAM not recognized

Solution: Check whether the DRAM is attached backwards, whether the DRAM is damaged, and check whether the H5 is attached properly.

0x03: DRAM failed the test

Solution: First lower the frequency and run the test, and then modify uboot to lower the frequency after running the test.

0x04: H5 CPU power supply abnormality

Solution: H5 needs to be attached to the 0R resistor at CPU_FB. H3 and H2 do not need to be attached.
