Open SDR

The Beagle Board is an OMAP 3 based single board computer. The OMAP3 processor combines an ARM Cortex-A8 general purpose processor with a Texas Instruments C64x family digital signal processor in the same package. This combination is an attractive system for developing software defined radio software.

This will get you started building the embedded SDR software. Further additions, including building OSSIE are in development. The following steps should generate all the files needed to turn an OSK into a SCA Radio.

WARNING: No instructions exist for restoring the software provided with the SFFSDR board. I can not answer any questions about the restore process, proceed at your own risk.

There is a listserv for Linux on the SFF SDR. To subscribe to the list send an email to listserv@listserv.vt.edu with the following in the body of the email. The subject line doesn't matter.

Basic procedure:

• Download required software
• Erase flash
  

So far just notes on how to flash images ...

Flash u-boot, assumes tftp download and u-boot named uboot.bin.

OMAP5912 OSK # tftpboot 0x10000000 uboot.bin
OMAP5912 OSK # protect off 1:0
OMAP5912 OSK # erase 1:0
OMAP5912 OSK # cp.b 0x10000000 0x0 $(filesize)
OMAP5912 OSK # protect on 1:0

Flash kernel, assumes tftp download and kernel named uImage.cc. Here are the u-boot commands.

OMAP5912 OSK # tftpboot 0x10000000 uImage.cc
OMAP5912 OSK # erase 0x40000 0x23ffff
OMAP5912 OSK # cp.b 0x10000000 0x40000 $(filesize)
