Sysupgrade, Fails ext4 Upgrade (LuCI)

Hi,

When I try to upgrade the flash on my ext4 (or squashfs, same issue) based router - it fails with an error message about the image not fitting ... but when I try the same file from the command line, it works fine (and flashes OK, two the 2 mmcblk partitions).

This is for my ESPRESSObin v5 device, if that makes a difference :laughing:.

I have had others confirm the same issue. Or is it that LuCI won't flash ext4 files?

Thanks!
