Dear all,
i am running uClinux but with a main line kernel 2.6.36.2 and trying to get 13
GPIO lines of my MCF5307, to do some tests driving an LCD display, as below:
static struct gpio ks0108_gpios[] = {
{ 0, GPIOF_OUT_INIT_LOW, "D0" },
{ 1, GPIOF_OUT_INIT_LOW, "D1" },
{ 2, GPIOF_OUT_INIT_LOW, "D2" },
{ 3, GPIOF_OUT_INIT_LOW, "D3" },
{ 4, GPIOF_OUT_INIT_LOW, "D4" },
{ 5, GPIOF_OUT_INIT_LOW, "D5" },Linux version
{ 6, GPIOF_OUT_INIT_LOW, "D6" },
{ 7, GPIOF_OUT_INIT_LOW, "D7" },
{ 10, GPIOF_OUT_INIT_LOW, "CS1" },
{ 11, GPIOF_OUT_INIT_LOW, "CS2" },
{ 12, GPIOF_OUT_INIT_LOW, "R_W" },
{ 13, GPIOF_OUT_INIT_LOW, "D_I" },
{ 14, GPIOF_OUT_INIT_LOW, "E" },
};
gpio_request_array(ks0108_gpios, 13);
The gpio_request_array() return without any error, but seems i can set
correctly levels only lines PP0 to PP3, not 4to7, 10,11,12,13,14.
Am i doing something wrong ?
Thanks,
angelo
