Hi,
I am trying to get an OMAP L138 on LCDK into USB gadget mode using gadgetfs. Unfortunatelly - or better predictably - it doesn't work. I'm unable to mount gadgetfs. Currently I'm working on the thesis that this happens because I cannot chose the correct peripheral controller mentioned in documentation.
I'm working with PSP 3.22.00.02 - in the document files it is mentioned that I have to select Inventra Highspeed Dual Role Controller (page 21 in UserGuide-03.22.00.02.pdf) . This selection has to be done in device drivers -> USB support submenu of menoconfig - but there is only a choice for this Controller if Host-side USB is selected, too. This conflicts with the shown listing on page 21 of UserGuide-03.22.00.02.pdf
I've already tried to go back to the LCDK SDK but make menuconfig shows the same behaviour.
Unfortunately I could not find any corresponding problem reports in e2e community or else. So I'm hoping for some ideas.

P.S. I've found some more information: this time I have compiled Host-side USB as a module which gives me the opportunity to load musb_hdrc.ko via modprobe. The command came back with:
musb_hdrc: version 6.0, ?dma?, otg (peripheral+host)FATAL: Error inserting musb_hdrc (/öib/modules ... /musb_hdrc.ko): No such device
