The code for musb gadget support is currently available on the omap3-dev-usb branch of the Beagle U-Boot git repository.
Current Status
- Currently the code enables the Beagleboard to be recognized as a USB ACM modem, and provides a u-boot console over it. It keeps the console over serial as well.
Known bugs
- None
Next steps
- Merge in mainstream?
Getting the source code
Checkout the git source for the musb gadget support from the Beagle U-Boot git repository. Get it by:
git clone git://www.sakoman.net/git/u-boot-omap3.git cd u-boot-omap3 git checkout --track -b omap3-dev-usb origin/omap3-dev-usb
Build (assuming Code Sourcery GCC 2007q3):
make CROSS_COMPILE=arm-none-linux-gnueabi- mrproper make CROSS_COMPILE=arm-none-linux-gnueabi- omap3_beagle_config make CROSS_COMPILE=arm-none-linux-gnueabi-
Getting started
- Load your new u-boot.bin image into the board using any of the existing methods. If you have a beagle running already a working u-boot, you can load it by serial using the 'loady' command and minicom or 'sb' (be sure to have lszrz installed in your distro). Then erasing the u-boot in flash and reflashing the new image with the following commands:
nand unlock nand erase 80000 160000 nand write.i 80000000 80000 160000
- Reboot your board and keep the user button pressed while applying power (see Known bugs).
- Attach a mini-b USB cable to the beagle. Your host should recognize an ACM CDC device (works out of the box on Linux and OS X).
- If you want to have the u-boot console over USB use the following command:
setenv stdout usbtty,serial; setenv stdin usbtty,serial; setenv stderr usbtty,serial
