I'm tinkering with the 10.x beta on a 3B+
One thing I'm trying to do is compile kernel 4.19 + its modules. I'm using a debian based machine to cross compile (loosely following
this info and combining it with the
wiki info)
On the 10.x beta running Pi3B+ I've done:
sudo modprobe configs
And gunzip the /proc/config.gz to then on the build machine use that config as a starting point (renamed to .config and make oldconfig). I've just entered my way through all the default answers to new config options.
When I then
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- zImage modules dtbs
Then after make install (using INSTALL_MOD_PATH=/sometemppath) I end up with a tree about 50MB worth of kernel modules, whereas the piCore 10.x size is only a few MB...
Any pointers how to approach this?
