Dear,
I configured GPIO pins 12 and 14 on the Armstone A9 as GPIO inputs, and disabled the SPI (Flags = 4).
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\DIGITALIO]
"UseAsIO"=dword:07fc07ff
"DataDir"=dword:00000000
"Prefix"="DIO"
"Dll"="fs_digio.dll"
"Order"=dword:00000097
"Index"=dword:00000001
"Ioctl"=dword:00000004
"Port"=dword:00000000
"DataInit"=dword:00000000
"FriendlyName"="Digital I/O driver for iMX6"
"Debug"=dword:00000000
However, measuring the levels on 12 and 14 (both through software and from an oscilloscope), I get a high level. Strange enough, the level of pin 14 is about 2.2 V, while the level of pin 12 is 3.3V.
Could it be that the SPI driver is still interfering with these GPIO pins?
I have following firmware:
Eboot: v 1.20
Nboot: PVN26
Kernel: V1.80 - Build Dec 17 2015
