JFFS2 filesystem corrupts immediately (Magic bitmask 0x1985 not found errors)

 

If you have this error it may be a problem with SPI frequency.

[   99.740000] jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x001d4070: 0xff0a instead
[   99.760000] jffs2: Empty flash at 0x001d4074 ends at 0x001d412c
[   99.770000] jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x001d412c: 0xffff instead
[   99.790000] jffs2: Empty flash at 0x001d4130 ends at 0x001d4194
[   99.790000] jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x001d4194: 0xff0a instead 

Mine was not related to erasesize or image creating. 

Had to lower my SPI Freq to 30Mhz instead 100Mhz in my dts file.  

I know, it is confusing but really that was the problem. 

Hope it helps.
