I am working on getting USB-uboot working on OSK5912. from linux USB gadget "device controller drivers" (i.e. kernel/drivers/usb/gadget/) it looks like USB core for omap1510 and OSK5912 is same..But not sure, please confirm
No idea. You will have to RTFM.
I done following steps. 1)make mrproper 2)make omap5912osk_config 3)go to include/configs/omap5912osk.h and edit this file with following macros. . #define CONFIG_DOS_PARTITION 1
#define CONFIG_USB_OHCI 1
Drop this. This would enable the old OHCI support.
#define CONFIG_USB_OHCI_NEW 1 #define CFG_USB_OHCI_MAX_ROOT_PORTS 1 #define CFG_USB_OHCI_SLOT_NAME "osk5912" #define CFG_USB_OHCI_REGS_BASE 0xfffba000 #define CONFIG_USB_STORAGE 1
#define CFG_USB_OHCI_BOARD_INIT 1 #define CFG_USB_OHCI_CPU_INIT 1
You *might* have to implement these in order to enable power, clocks ...
#define CONFIG_CMD_USB 1
4)after this, I am able to see USB command enabled on Uboot console. but I am not able to see Mass-storage detected after inserting pendrive and doing "usb start"
You probably missed some initialization. Carefully check the documentation of you CPU and implement it in the functions above.
- from docs/README.generic_usb_ohci, It looks like usb_board_init/stop and
usb_cpu_init/stop functions are missing and needs to be implemented.
Exactly.
