AM3352: USB enable in U-boot

Part Number: AM3352


Hi All,

We have designed a customized board with AM3352 processor with 1 GB DDR3 and 512 MB NAND Flash. We have TWO USB ports. We are trying to Enable and test in U-Boot itself. We are using am335x-evm-linux-rt-sdk-src-04.00.00.04.tar.xz. When we enable the SPL/TPL --> Support USB Gadget drivers in U-Boot we are getting the following issue in U-Boot compilation,

LD      u-boot
common/built-in.o: In function `run_usb_dnl_gadget':
/home/cornet123/u-boot/common/dfu.c:74: undefined reference to `usb_gadget_handle_interrupts'

    Have you done any change in the uboot source code?

    After command "make am335x_evm_config", the USB gadget driver support should be already enabled in SPL, you don't have to enable this option specifically.

    By the way, I tried to build the uboot in am335x-evm-linux-rt-sdk-src-04.00.00.04.tar.xz, but don't see such error.
