Image build failing, can't see why

For Developers

Hi

I've been trying to build an image from scratch for a Asus RT-AC66U B1 router.

I've selected bcm53xx and generic from the menuconfig, I've also tried asus_rt-ac68u. The Build is failing but there doesn't seem to be much info on why, here the tail of my make log. If anyone can shed some light on what going wrong it would be much appreciated:

Run make -j1 V=sc to find the error EASILY (it isn't the only way).

I was using the default configuration for this build. Where is the setting for the maximum size allowed?

It is related to the available flash partition size on the device.

Possibly the current kernel is just too big for the space reserved for it by the OEM manufacturer.

Hi Grommish

I did also do a run with -j1 V=sc, didn't seem to give any more info that would be useful. I'm happy to run it again and send the tail of that if it would help?

Thanks

Hi Hnyman

What I mean is I'm running this image build with the default configuration, given by make defconfig so I'm not sure why it should be over running the available space. I was just wondering which file and where would I find the setting for the size of the flash set for the build, i.e. where is it getting the size to know it's a error? So I can double check that it is correct.

Thanks

Sam

The bcm53xx image settings are in

E.g.

But I have no experience with the Broadcom targets and the recipe functions there, so you need to parse the logic by yourself.

Hi Hnyman

That gives me a head start, I am working my way through the whole makefile. But my afternoon can be concentrated here :slight_smile:
