Re: using gadgetfs on DM365/355
Hi, One question regarding this Gadget FS, do I have to mount that as a device on linux host so that I can use this driver? if yes, can anybody tell me why? I'm not sure if I'm following your question. The gadgetfs provides a file system on the embedded Linux that you need to mount to make your user-space driver work it that's what you mean. On the USB host side you need a class driver for whatever class you are implementing. I originally thought Gadget FS is just a API driver which exposes USB endpoint interrupts to user mode, so that User can design USB control parsing engine in application threads, Is there a need to do the mounting? GadgetFS mounts a file system that provides a file that you open in user space to control the ep0, and once the device is configured it creates files for every endpoint that you created. Try running the usb.c example code and you will see how it works.

using gadgetfs on DM365/355
Dear All, I am trying to build my UVC Gadget API Driver by using Gadget FS, since we do want to handle USB controls in User space, so we will also modify the USB.c for our application. One question regarding this Gadget FS, do I have to mount that as a device on linux host so that I can use this driver? if yes, can anybody tell me why? I originally thought Gadget FS is just a API driver which exposes USB endpoint interrupts to user mode, so that User can design USB control parsing engine in application threads, Is there a need to do the mounting? I tried Gadget Zero and serial, I have not mounted anything. Thanks a lot Gary ___ Davinci-linux-open-source mailing list Davinci-linux-open-source@linux.davincidsp.com http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
