I'm building an image for a 'Tenda W306R V2.0' and so far it booted fine..

Now I need to modify the build to use the 8m flash my router has (custom mod)

I'm building the image with verbose and as far as i can see.. it has a limit of 0x3B0000 for the image size, also the partition created seems to only use 4M

df shows:

/dev/mtdblock5 1472 204 1268 14% /overlay
overlayfs:/overlay 1472 204 1268 14% /

Any pointers will be appreciated, Thanks in advance!

Flash size&partitions are defined by mtdparts parameter of kernel command line. You can see it by

cat /proc/cmdline

Value of parameter is set in /trunk/target/ramips/image/Makefile. So you can add new profile for your custom mod based on GENERIC_8M

Thanks

I figured out where to make the changes in the Makefile.

This allows a bigger image, and also the partition in the router is 8M

For the record, in case someone else need this:
