Hi,
have a look at the codes in board-da850evm.c got the codes
static struct i2c_gpio_platform_data da850_gpio_i2c_pdata = {
.sda_pin = GPIO_TO_PIN(1, 4),
.scl_pin = GPIO_TO_PIN(1, 5),
.udelay = 2; //250kHz
};
and read some comment in u-boot said there is a bug in i2c hardware, will not work under freq of 10KHz frequency
so, how we could use i2c hardware ?
best regards,
Power Pan
