Rootfs error of Buildroot for nuc980
yongzhiliu1006 opened this issue · 3 comments
Dear sir:
I am using buildroot to generate rootfs image for a 980 dev board. The 980 MPU boot from a spi nor flash w25q256. The uboot and kernel seem to be ok from the message printed. But the rootfs from buildroot seem to be wrong."**devtmpfs: error mounting -2". It puzzled me for a long time. And I tried several version of buildroot, no one worked on the board. Please give me some advice on this issue. Thank you very much!

yaffs2 is for NAND flash, but you are boorting from SPI NOR.
You may have selected the wrong defconfig.
What's the name of board you are using?
The issue solved. I do not fully understand the mkfs utility, packed wrong dir.
