The problem about how to download the filesystem to the nand flash

Hi,

Now we have downloaded the x-loader,u-boot,kernel to the nand flash of AM3517. But the problem is that the flash tool can not be used to download the filesystem. I tried to download the kernel and filesystem through USB. But the board can not recognize the U disk ,maybe the U-boot does not support the USB storage. (u-boot-2011.09-psp04.06.00.08)

Could you tell me how to set the U-boot to support the USB storage?

Is there any tool can be used to download the filesystem ?

TKS!

kooking:

可以在 u-boot 下tftp下载,也可以进文件系统后烧写

回复 kooking:

关键是我们的项目最终要去掉网口,所以想通过其他方式烧写文件系统,例如在u-boot下通过USB烧写内核和文件系统,但是U-boot起来后,输入USB start检测不到U disk,我觉得是u-boot没有支持USB storage,如何修改U-boot使得它支持USB?

回复 weng lucheng:

有SD卡接口不,从SD卡烧写也比较方便

tony2:

最好的选择就是SD卡,我们就用这个方法升级

Yaoming Qin:

这个TI没有现有的代码发布,您可以去开源论坛上找找了。

回复 Yaoming Qin:

可以试试在u-boot添加USB DFU

在u-boot添加USB DFU有相关的设计资料吗?
