With AM3359AZCZ100 (ZCZ) work OK.
With AM3358BZCZ100 (ZCZ) not enable o pin 22 to headerP9 to GPIO.
cat /sys/kernel/debug/gpio
GPIOs 0-31, gpio:
gpio-2 (sysfs ) out hi
cat /sys/class/gpio/gpio2/direction
out
cat /sys/class/gpio/gpio2/value
1
My setup:
Linux created with Yocto Project 1.7
Kernel 3.14
With Am3359AZCZ OK, with AM3358BZCZ no.
OBS: I’m create .dts with PinMux to GPIO0_2 (0x150) and nothing has changed.
Now the pins GPIO112 and GPIO51 work in AM558 and AM559 OK no problem.
Suggestions?
