Hello Brian,
2009/6/23 Brian Silverman bsilverman@iveia.com:
I have created a patch for the OMAP3EVM u-boot to create an image for download into OMAP internal RAM (64k). This allows a complete boot to Linux over USB only, without any RS-232 serial cables. The difference between this and Nishanth Menon's procedures (found here: http://nishanthmenon.blogspot.com/2008/12/towards-creating-beagleboard-n and.html) is simply that the RS232 serial port is not required.
If anybody has any input into this, or finds this useful, please share...
I can imagine it would be useful to someone.
Here's an executive summary of the boot process: - Setup OMAP3EVM to boot via USB - Start Martin Mueller's omap3_usbload to download the u-boot.bin image - Run a kermit script to talk to the board over /dev/ttyACM0, and download uImage/ramdisk images. - bootm - Linux boots to the command line.
Also note: this builds off of a u-boot USB dev branch, not mainline u-boot.
To what version u-boot is it build exactly. This is not clear to me. If you want this to be accepted in mainline, please post the patch inline, and follow this procedure: http://www.denx.de/wiki/U-Boot/Patches
Kind Regards,
Remy
