The H3 DT overlays function of NanoPi Neo is wrong.

Hello everyone, 

 

After many investigations, it was found that its function configuration was incorrect:

In the H3 data sheet, the correct configuration of I2C0 should be ALT2, but it is incorrectly set to ALT5. In the same way, SPI0 is also wrong: SPI0 should be ALT3 and was incorrectly configured as ALT4, so these peripherals cannot work normally.

 

The armbian version information for this error is as follows:

After finding Orange PI + 2E ( Same use H3 ), I verified that my judgment is correct, so is there any clue to solve this problem?
