I have a glance at the kernel’s installer configs and tried the netboot
without any modification. Some work should be done to make debian-installer
support OMAP5 uEVM (e.g., ethernet driver etc).
By waiting the kernel building with some initial attempted configs added,
just one question to ask. I looked through the
debian/installer/armhf/modules/armhf-armmp/, but it looks like none of
files is about regulator modules. However, according to my previous
experience, missing regulator driver modules is the main reason that
the old debian kernel doesn’t support OMAP5 uEVM. How does debian-installer
deal with this situation (if it does need extra regulator drivers included?)
Cheers,
