modify U-boot environment variables in linux

從Angstrom on gumstix的fs裡, 挖出下列三個檔案

/etc/fw_env.config

/usr/sbin/fw_printenv

/usr/sbin/fw_setenv

也可利用這三個檔案在Android on gumstix上modify U-boot environment variables

顯示參數

$ fw_printenv

設定參數

$ fw_setenv mmcargs setenv bootargs console=ttyS2,115200n8 androidboot.console=ttyS2 root=/dev/mmcblk0p2 rootdelay=2 omapfb.mode=dvi:1024x768MR-16@60 init=/init
