USB in U-Boot on DM355

Other Parts Discussed in Thread: DA8XX, OMAP-L137

Hello

I am trying to load my uImage from a USB drive on the DVEVM355, so I am trying to remake U-Boot with USB support.

I added the following to the end of the U-Boot configurations section in the dm355_evm.h file

#define CONFIG_DOS_PARTITION 1
#define CONFIG_USB_OHCI    1
#define CONFIG_USB_STORAGE 1
#define CONFIG_USB_DA8XX   1

and have the following CONFIG_COMMANDS

#define CONFIG_COMMANDS        (CFG_CMD_DFL | CFG_CMD_ENV | CFG_CMD_NAND | CFG_CMD_LOADB | CFG_CMD_LOADS | CFG_CMD_MEMORY | CFG_CMD_ASKENV | CFG_CMD_RUN | CFG_CMD_AUTOSCRIPT | CFG_CMD_BDI | CFG_CMD_CONSOLE | CFG_CMD_IMI | CFG_CMD_BOOTD | CFG_CMD_MISC | CFG_CMD_PING | CFG_CMD_DHCP | CFG_CMD_NET | CFG_CMD_USB | CFG_CMD_FAT)

when I make U-Boot I get the following linker errors at the end of the make;

        --start-group lib_generic/libgeneric.a board/dm355_evm/libdm355_evm.a cpu/arm926ejs/libarm926ejs.a lib_arm/libarm.a fs/cramfs/libcramfs.a fs/fat/libfat.a fs/fdos/libfdos.a fs/jffs2/libjffs2.a fs/reiserfs/libreiserfs.a fs/ext2/libext2fs.a net/libnet.a disk/libdisk.a rtc/librtc.a dtt/libdtt.a drivers/libdrivers.a drivers/nand/libnand.a drivers/nand_legacy/libnand_legacy.a drivers/sk98lin/libsk98lin.a post/libpost.a post/cpu/libcpu.a common/libcommon.a --end-group -L /opt/mv_pro_4.0.1/montavista/pro/devkit/arm/v5t_le/bin/../lib/gcc/armv5tl-montavista-linuxeabi/3.4.3 -lgcc \

common/libcommon.a(usb_storage.o)(.text+0x658): In function `usb_stor_CBI_get_status':

 

The libcommon.a library and the usb.o have been recompiled.  From what I can see in the usb.c file, if (CONFIG_COMMANDS & CFG_CMD_USB) then the missing references should be there.  Since U-Boot makes and works okay without the CFG_CMD_USB, I assume I need to do something different.

Any ideas on what the problem is?

Thanks,

Doug

    I have not seen this done on DM355; however, for OMAP-L137, the following options are enough

    #define CONFIG_USB_STORAGE 1
    #define CONFIG_USB_DA8XX   1

    The second of these appears to be specific to OMAP-L137; I wonder if there is a similar one for DM355?  If not, this level of support may not be available in the u-boot source you are using.

    OMAPL137 and DM355 USB controllers are pretty similar.  One would have do put in the low level init code to get DM355 USB to work on U-Boot.

    Thanks for the replies.

    A couple of questions.  I am using U-Boot 1.2.0.  From what I can find OMAPL137 uses U-Boot 1.3.3.  Can I use the init code out of version 1.3.3 (or some other version) in U-Boot 1.2.0?

    I only have access to the DaVinci extranet, which does not have the OMAPS.  Is there a link I  can access the OMAPL137 U-Boot source code at?

    Thanks for the help,

    Doug
