W25q256的芯片，已经改成64K的擦写方式了，系统可以识别，使用-p 0x500000 -e 0x10000 -s 0x100 参数
如果作为根文件系统，出了一大堆提示后，无法挂载导致启动失败。如果手动使用mount -t jffs2 也会有下面提示很多，但是最后ls 可以看到里面的文件。还有什么需要注意的地方吗，会不会和PG8.9有关系？
When BTSEL = 11, Boot from SPI Flash, the MISCCFG defines the
SPI Flash type and data width.
00 = SPI-NAND Flash with 1-bit mode.
01 = SPI-NAND Flash with 4-bit mode.
10 = SPI-NOR Flash with 4-bit mode.
11 = SPI-NOR Flash with 1-bit mode.
这个是什么意思呢？NUC9有硬件ECC配置么？谢谢
