hi every1, I'm trying to use the 34 pin GPIOs I'm unable to access the 25,26,27,29,30 which belongs to GPIOE register and base values are 128,129,130,131,132 respectively i tried the following comands to drive a LED in linux terminal echo "128" > /sys/class/gpio/export echo "out"> /sys/class/gpio/gpio128/direction ( then thers no output I mean Led is not ON ) but where as I tried with the 28th pin GPIOG2 with a base values of 194 echo "194" > /sys/class/gpio/export echo "out"> /sys/class/gpio/gpio194/direction //the LED is ON echo "in"> /sys/class/gpio/gpio194/direction // LED is OFF so can any1 guide what might be the problem is the pin connections wrong or is the GPIOE doesnt support or what is that exactly I need to do to use the GPIOE pins I mean 25,26,27,29,30 of the 34pin GPIO connector thanks in advance, ARMtry.
problem with GPIOE on 34 pin connector
If you use SPI or I2C then this pins are used by drivers and couldn't be driven by gpiolib. But not 100% sure.
