购入两块MINI6410的板子,发现SD卡烧写程序正常,但是使用USB-OTG下载的时候出现问题。
U-BOOT和KERNEL下载都正常,但是下载ROOTFS_QTOPIA_QT4.IMG文件时,下载就卡在那里了,怎么也不动。
看了一下终端的打印信息
这是U-BOOT下载好后的信息:
Enter your Selection:v

这是KERNEL下载之后的信息:

这是文件系统下载后的信息:

然后就一直停在那里,怎么也不动了。
怀疑,是不是我的文件系统太大,从USB-OTG下载下来之后,先缓存在我的256M RAM里面,然后再写到FLASH里面去的
U-BOOT和KERNEL两个文件都不大,但是ROOTFS文件系统很大,差不多到250M了,所以RAM 空间不够用导致的?
