Installation
You have to:
- reflash your rootfs or copy these modules on your target in /lib/modules/2.6.18.1/extra/gpio (don't forget modules.dep file),
- copy loadgpio.sh script on your rootfs in /etc/
After that you can launch:
# sh /etc/loadgpio.sh
or look inside this script if you want to manually enter the module parameters:
# modprobe gpio portB_init=0,0,0x00FFFF00,0,0,0,0,0,0x0FF00000,0,0,0,0,0,0,0x0FF00000
gpio module parameters are values for PORTA, PORTB, PORTC, PORTD configuration registers in following order:
DDIR, OCR1, OCR2, ICONFA1, ICONFA2, ICONFB1, ICONFB2, DR, GIUS, SSR, ICR1, ICR2, IMR, GPR, SWR, PUEN,
If you don't know what these registers means, load the module without parameters !!
