有哪位大佬，在做过qspi jffs2的rootfs
我的ZYNQ 7020，rootfs已经烧录到 rootfs分区：

但启动时挂载jffs2文件系统失败：

没有成功，是不是还有特别的地方要配置？

呵呵，已经弄好了，不容易啊！

怎么弄好的，我制作文件系统，设这个：
mkfs.jffs2 -d rootfs/ -o rootfs.jffs2 -e 0x1000 -s 0x1000   //报这个 ：Erase size 0x1000 too small. Increasing to 8KiB minimum
然后烧写的时候出现这个：
root@prime_rel:~# flashcp -v /mnt/rootfs.jffs2 /dev/mtd4
Erasing blocks: 1656/1656 (100%)
Writing data: 6621k/6621k (100%)
Verifying data: 2690k/6621k (40%)File does not seem to match flash data. First mismatch at 0x0029e000-0x002a0800
还是没起来，请教楼主怎么搞好的

笨办法，换flash
