Linux/PROCESSOR-SDK-AM437X: USB console configuration in U-boot

Part Number: PROCESSOR-SDK-AM437X


Tool/software: Linux

I am trying to configure a USB serial console by the following defines.

#define CONFIG_MUSB_UDC

#define CONFIG_USBD_HS

#define CONFIG_USB_TTY

#define CONFIG_SYS_CONSOLE_IS_IN_ENV

I get the following unresolved references in udc_init

musb/musb_udc.c:939: undefined reference to 'musb_platform_init'

musb/musb_udc.c:959: undefined reference to 'musb_cfg'

Looking at the musb_udc.c file where the udc_init function resides it has the following

#if defined(CONFIG_USB_OMAP3)
#include "omap3.h"
#elif defined(CONFIG_USB_AM35X)
#include "am35x.h"
#elif defined(CONFIG_USB_DAVINCI)
#include "davinci.h"
#endif

I don't believe any of these files are applicable to the am437x

Has anyone tried configuring a USB console on the AM437X platform
