Is there any way to increase the file size limit on UBIFS beyond
2Gbytes? I have tried enabling the kernel ‘Support for large block
devices and files’ under ‘Enable the block layer’, but the 2G limit
persists.
Regards,
Dave.

We never tested this, but should not be. AFAIR, UBIFS theoretical
limitation should be something like 16TB, but I tried tested the maximum
file size.

UBIFS has nothing to do with block devices. This is a very specialized
FS for bare flashes:

So that option has no effect for UBIFS.
