大家好！原有的DM365 sdcard_flash_DM36x.bin工具只支持 小于2G的mmc/sd卡烧写映像，现在想改写关于SD卡的初始化程序让其支持4G或以上SDHC卡烧写程序，大家有没有相关的初始化程序或者相关资料提供参考，非常感谢！！
Long Wei,
dvsdk 4.01开始就支持在SDHC上创建可启动的sd卡。

Utility for creating bootable SD cards has been enhanced to support SDHC cards.
具体操作请参考mksdboot.sh，里面使用的utility是uboot下的uflash。
谢谢你的回答！问题已解决 我是参考的这篇帖子http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/100/p/40267/146446
