[ 0.748076] m25p80 spi32766.0: unrecognized JEDEC id bytes: 0b, 40, 18
[ 0.754729] m25p80: probe of spi32766.0 failed with error -2你的FLASH ID没有再表中
重新检查了下，表中的ID写错了1位：0b4018写出了0b4008了。
这个问题解决了后，出现下面问题：
[ 3.669876] jffs2: Cowardly refusing to erase blocks on filesystem with no valid JFFS2 nodes

[ 3.686864] VFS: Cannot open root device "31:03" or unknown-block(31,3): error -5
这个是根文件系统有问题吗？
谢谢！
是flash_info spi_nor_ids[]表吗？这个表已经加了flash的ID。
后面还有错，与这个有没有关系
