USB gadget kernel module with RPi zero

<< < (5/18) > >>

patrikg:
By using the modinfo command.

modinfo g_ether

Sometimes the depends: shows what modules it needs.

patrikg:
Why not test to include the hole gadget directory to your own module extension pack.
And this is how to managed to do the module extension pack.

You modify the example above with just two lines. And also the dwc2 driver.


--- Code: (bash) ---mkdir -p /tmp/package/usr/local/lib/modules/4.4.39-piCore\+/kernel/drivers/usb/gadget/
cp -r /home/tc/modules/4.4.39-piCore\+/kernel/drivers/usb/gadget/* $_
--- End code ---

There are also lots of parameters to be set.

--- Code: (bash) ---modinfo g_ether.ko

Linkan:
Okay, I think I've resolved the dependencies but still I can't load the module with the same error. Do I have to manually specify all the parameters listed by `modinfo` to the kernel module?

jgrulich:
Hi, may be, that my approach is quite different, but why not to use the u-boot bootloader to do all that stuff?
It is designed exactly for this purpose. It has USB and ethernet drivers and you may simply flash the card and do even much more. It's really powerfull. Look: http://www.denx.de/wiki/U-Boot/WebHome
