DM365: USB serial/ethernet gadget support under uboot

Prateek Bansal

Hi,

How do I test whether DM365 uboot support serial or ethernet gadget support under USB ?

When I look at PSP 3.xx.00.37 tag under uboot git, I see gadget, host and musb directory. Under gadget, I dont see any davinci specific files and as such not clear whether we support these modes.

http://arago-project.org/git/projects/?p=u-boot-davinci.git;a=tree;f=drivers/usb;h=c74978b1e5382efc67e3598dcc1eef5cfa4ef3ea;hb=5ffbb11723b3b919ef85513b6fc68a499c2e6a8c

My customer is interested in getting kernel and filesystem over USB host and would like to understand what options are available?

If we dont have this support under our Arago branch tree, would appreciate any pointers to patches on other community list to add this support.

 

Thanks,

Prateek

    Prateek,

    I looked at the arago uboot tree and seems uboot usb support is added. Default mode is configured in host mode in davinci_dm365evm.h. You can refer below document on how to use host mode in uboot,

    http://ap-fpdsp-swapps.dal.design.ti.com/index.php/AM35x-OMAP35x-PSP_03.00.00.05_UserGuide#MUSB_Host_Support

     

    Now, to enable device mode you need to change the davinci_dm365evm.h. Please refer below page for more detail on using uboot serial.
