Hello,

I am trying to set a default size for the rootfs.jffs2 generated by
Yocto.
For this purpose, if I am not wrong, this can be done using the
IMAGE_ROOTFS_SIZE option.

But where  I have to configure this option ? So, in which
configuration file ?

You can define it either in your image recipe (if you have a custom
one), or in conf/local.conf.

It seems that this detail has not been specified in the reference manual.

True, but this is a more generic mechanism that we chose not to repeat
for each variable. Essentially, the documentation at
https://docs.yoctoproject.org/dev-manual/common-tasks.html#customizing-images-using-local-conf
explains that your image can be customized through conf/local.conf or by
writing your own image recipe.

I agree the manual is so big that this may not be clear.

Cheers
Michael.

Thanks,
Simon
