Confirm that T2 may have a fault, check that T2 is not short-circuited, and trace that T2 external BIOS waveform is normal. Rom has started to work, and T2 has also turned on the CD3215 I2C bus with 1.8v waveform and voltage. In this case, directly replace the CD3215 chip, and both of them can be changed together, which can boost the voltage, boot normally, and turn on the machine perfectly.
