sunxi_gpio_probe can't find script.bin

Hello everyone!

The sunxi_gpio_probe can't find script.bin :(

I changed the kernel then can not make the module sunxi_gpio find the script.bin file to create the classes. I see that it is loaded early in the boot but something happens and does not work.

I saw:

Please, anyone have any clue what to do? I put log tacched.

The message isn't that it can't find your script.bin (that's loaded by uboot before the kernel starts); it's saying it can't find the proper gpio section in it.

If you're using the gpio-sunxi drivers, make sure you have a gpio_para section in your script.bin:

gpio_used = 1
gpio_num = 2
gpio_pin_1 = port:PH14<0><default><default><default>
gpio_pin_2 = port:PH15<0><default><default><default>

If you're using the sun4i-gpio drivers, I can't help you.



  I have these entries, if the system load the old kernel they work (but I get no wifi: (sniff.

  There are other more efficient ways to manipulate GPIOs?

  Thanks for your help,
Best Regards
