板子上配备的是winbond的nor flash 芯片，内核启动挂载jffs2系统时出现故障，

但是能够启动进入操作系统，进入完成后执行ls，cd等基本命令也会提示类似错误，求解

烧写过程一切正常，我的ucl.xml如下：

楼主你好，请问烧写过程有没有出现什么错误？

只看该作者 · 2015-12-22 17:34

还有你这里是如何烧写的呢？

换ubi吧，现在官方的都搞ubi了......

烧写过程一切正常，使用的MFGTool连接otg线直接烧写的。

开始的时候尝试使用UBI，因为是用的Nor Flash，每次都会core到DMA上，NXP Community也提到了这个bug，但没有见到任何Patch。

我没有权限直接发表链接，想看的话，何以在下方地址前加上https:
//community.freescale.com/docs/DOC-93632

"In this example, we only used the JFFS2 file system. To support the UBIFS, there is a known issue, that the UBIFS will use vmalloc to alloc memory, and if SPI driver used the DMA, kernel will halt with error "kernel BUG at arch/arm/mm/dma-mapping.c:409!"."

另外挂载initramfs，然后测试nor flash的读写和擦除，一切都正常！

2.6.35内核版本使用nor flash和ubi有问题，官方为啥不提供patch，或者更高版本的kernel支持？

这个我们也不清楚，目前新版本BSP的更新就是i.mx6系列的，别的系列的都没有再更新了。

临时规避了下，控制器使用PIO模式，文件系统换成ubi的。
