USB Driver for OMAP3EVM Board?

BeyongJong Kim
Prodigy 130 points

Reference to Release Notes with SDK-02.01.02.11.

Features:

1. MUSB OTG: Slave mode

2. MUSB OTG: Host Mode(MSC, HID, Audio, Video)

3. MUSB OTG: OTG Mode(HNP, SRP)

4. EHCI Host: (MSC, HID, Audio, Video)

So, I want to support the Host Mode and OTG.

If USB connected  between Windows PC and Target(OMAP3EVM),  I think the Windows Driver for usb.

How about you?

 

So,  we are using the OMAP3EVM Rev D.

If want the USB EHCI Host, what's modification ?

    I am not exactly sure what your question is here. When using the OMAP3 in slave/gadget mode such as if it was configured to be a mass storage class (MSC) device than the Windows USB driver would work with it.

    The original OMAP3 EVMs did not have EHCI implemented, so a rev D board would need to use a daughterboard like the Mistral Multimedia Daughterboard.

    Hi,

    You can enable Inventra USB controller on OMAP (using menuconfig) in Device mode.  Pl. do enable the right device class applications such as File Storage/CDC/RNDIS etc.  With this OMAP would enumerate with PC as a device.

    You can also enable EHCI support in the USB menuconfig and connect say high speed devices to the EVM EHCI port.  If you want to work with FS/LS devices then you would have to connect a HUB to the EHCI EVM port and connect all USB devices to the Hub port.  This configuration would ideal for your host needs.
