syslinux filesystem size limitation

syslinux filesystem size limitation

Hello,
	In yocto I find that the live image (hddimg) is generated using
syslinux (in bootimg.bbclass). But, I find there has been no check
enforced to find whether the filesystem size exceeds 1 GB. The image
will not boot if the hddimg size exceeds 1GB. This is due to the
limitation in syslinux.

How to address this issue? Is there any other alternate solution for
this? Should I file a bug report for this?

Yes, this sounds worthy of filing a bug. Bonus points for patch 
submissions to fix it. ;)

I've filed the bug report for it.
https://bugzilla.yoctoproject.org/show_bug.cgi?id=2138

Will try to add patch if possible.

Where are you getting this information?

From what I can gather, syslinux 2.xx didn't support FAT32, which
limited the maximum filesystem size purely due to limitations of FAT16.
Syslinux 3.xx supports FAT32. We are building syslinux 4.xx in Yocto.

I'm fairly certain I've built syslinux images larger than 1GB without an
issue.

Can you provide a failure case?

In order to answer this, I have added my comments on the bug listing
https://bugzilla.yoctoproject.org/show_bug.cgi?id=2138

I guess it would be more appropriate there.

For the benefit of others who arrived at this thread via search I am
writing this.

Apparently, there is no 1GB limitation with syslinux. The problem was
due to mkdosfs tool in poky edison branch. The complete discussions
about this can be found in the (long) comments section of this bug.

I would like to thank Darren for helping me in debugging this problem.
