Hi, All

As we know, MTD has partition size limit of 2G. Do you know the size limit
of UBIFS partition and file size?

Thanks in advance.

Hi, All

As we know, MTD has partition size limit of 2G.

I think it is much larger now, after we converted offsets and sizes to 64-bit variables.

I'm too lazy to look at ubifs-media.h, but all sizes are 64-bit variables there. But I never tested UBIFS on really large UBI volumes. Never believe theoretical limits - test.

Which version of kernel imported the 64bit support for MTD? I'm using 2.6.28.10.

2.6.28 is ancient. I do not remember the veriosn, try 'git log drivers/mtd'
