Looking at the FEX file for an Olimex-A20 and a Cubieboard this entry looks like this.
pmu_adpdet = port:PH02<0><default><default><default> But on the Olimex-A20 this pin is connected to a notification LED. It is not used in the schematic of the Cubieboard that I found. Looking at the AXP209 I found on the Olimex board that the GPIO1 is connected via a potential divider to USB VBUS In the drivers I found a reference to this pmu_adtdet that seems to be used to switch the charging current from 2 different settings. As the AXP209 docs are all in Chinese it is almost impossible to work out what the settings are for the GPIO and I can only assume that the FEX settings are actually for the AXP209 GPIO and not the GPIO on the A20 itself? Would this assumption be correct. I have an issue with the A20 running on battery and it is reporting that the percentage left is not the same as the percentage when I apply external power to the board. This is not related to the above, it was just that I spotted this when trying to track down the issue. -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
