I am trying to use GPIO1.4 (SODIMM 19) and GPIO1.5 (SODIMM 21) as GPIO instead of UART5 pins. I have modified the device tree accordingly, but the pin states do not change when executing any of the following commands from the console:
gpioset 0 4=0 gpioset 0 4=1 gpioset 0 5=0 gpioset 0 5=1
GPIO1.4 is always high (3.3V) and GPIO1.5 is always at approx. 1.7V.
My device tree is based on the Iris v2 device tree and I have attached my diff file.
Does anybody know what is the problem?
