DM8148 USB gadget drivers module build error

Vik

I got DM8148 EVM recently, and trying to enable USB gadget drivers.

I took ti814x_evm_defconfig, I enabled that feature in menuconfig,selected several modules like Gadget Zero, Ethernet, Serial, but every time I am getting error during "make all" or "make modules"

...

Kernel: arch/arm/boot/zImage is ready
Building modules, stage 2.
MODPOST 15 modules
ERROR: "omap_set_dma_src_data_pack" [drivers/usb/gadget/omap_udc.ko] undefined!

make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2

I tried EzSDK 5.02.02.60, TI-814X-LINUX-PSP-04.01.00.03, .05 - it's the same. I guess I am missing something in configuration. Though, the same settings on another platforms do not produce error.

please refer to Users' Guide at http://processors.wiki.ti.com/index.php/Usbgeneralpage#MUSB_controller_in_gadget_mode . You need to chose "Inventra USB peripheral controller" for gadget mode. Menuconfig->device drivers->USB support.
