beagle板出厂 UBoot 修改方法

beagle板出厂时Uboot的设置是启动Linux,以下方法显示了如何将其改为可以运行QNX：

1>	连上串口线，打开超级终端，设置串口速率为115200
2>	当出现Hit any key to stop autoboot:  10 的时候，敲任意键，停止uboot的启动
3>	输入如下的命令：(保证你的SD卡里面有QNX的启动文件 beagle.ifs)
              OMAP3 beagleboard.org # setenv loadaddr 0x80200000
              OMAP3 beagleboard.org # setenv loaduimage fatload mmc 0 ${loadaddr} beagle.ifs
              OMAP3 beagleboard.org # setenv mmcboot go 0x80200000
              OMAP3 beagleboard.org # saveenv
              OMAP3 beagleboard.org # reset
