Hey,
Look like there is a new OpenWrt major release V19 coming soon.
A quick view to the file let me think that the CF-E110Nv2 is still considered to be only a 16MB flash device while both 8 and 16 are existing.
Could you generate both 8MB compatible code and 16MB compatible code FW version like it is done for some other devices (eg: NEXX3020)
