Hello there, I am having difficulties with some xilinx gpios and the xilinx-2.6-xlnx kernel. As far as I can tell the kernel is configured correctly for gpio. I can see that the module_init function "xgpio_init" is called, and that bus_add_driver and driver_add_groups returns without error. But I cannot see that the probe function is called. /proc/misc doesnt list a driver for the gpios. I am not sure where to go next as there is no error printouts.
I have seen other peoples consoles stating that the gpio is mapped to xx but this doesn't happen for me. I am using the default bit file for the ml507 board, and have created device files /dev/xgpio0 /dev/xgpio1 etc with major 10 and minor 185 However if I try to open these devices the open fails. I would rally appreciate it if someone could give me some pointers as to what to look for, or how a to go about debugging this. Many thanks Peter Scott
