I'm using an Alix 1D board for my system, and I'm trying to use its' GPIO header to control this relay board (http://arduino-direct.com/sunshop/in...t_detail&p=181
Well, I know that the Alix can drive the relay board properly, because if I change the GPIO pin's value on the BIOS, the relay opens/closes accordingly.
Anyway, I'm not able to control it using the /sys/class/gpio fs.
The cs5535-gpio module is loaded, I set up the pin for export and set it for writing (out).
Assigning a value (1 or 0) to the pin doesn't operate the relay board at all.
Kernel is v3.2.17.
