can't use IO_CP_GPIO_DIRECTION command

[belhaj]

Hi,
it's my first post in the forum, it's the first time that I use a Lantronix product
and I need some help.

as mentioned in the title, I can not use the IO_CP_GPIO_DIRECTION from the cpm_ioctl,
this command gives me an error ( bad address) when I use it to set the direction of the CPs.

I just want to mention, that the other commands from cpm_ioctl are working for me,

 case IO_CP_GPIO_DIRECTION:
            if (mask == 0)
            {
                ret = drv->device->state.direction;
            }
            else
            {
                ret = cpm_cp_direction(drv->device, mask, value);
            }
            break;

please help me
belhaj.
