Hello Debian tinkerers,
I am writing this as a follow-up on an existing debian-user thread
and some private replies which suggested that the recommended place for
questions related to ARM SBCs would be here.
The goal behind the original question linked above was to get an
unmodified Debian 10 onto the SBC without any external sources
During the past days, I finally arrived at a means to generate an image
for Debian 10 on the Sinovoip Banana Pi M2+EDU (Allwinner H3 SOC,
512 MiB RAM). Before, I had a working process for Debian 8 with kernel
and bootloader taken from armbian and throughout the development, I
managed to upgrade the process to Debian 10 and then even use an
unmodified Debian armhf-lpae kernel. Additionally, due to the removal
of a dependency on docker and the use of `mmdebstrap` instead of
`debootstrap`, the building process could be simplified and is now
running much faster than before.
Unfortunately, the result is (still) not entirely “unmodified“.
For now, the following changes wrt. a “proper“ Debian exist:
* u-boot (file `u-boot-sunxi-with-spl.bin`) is still taken from
armbian. I could not get it to work with either “mainline“ u-boot
which hangs at “Starting kernel...” or Debian's u-boot which
turns on the display, but does not do any output and does not boot --
no error message available...
* The kernel-upgrade process needs an additional script to generate
`uInitrd` and `boot.scr` files required by u-boot. I wrote that
script as a sort of “heuristics“ for kernel upgrading. Currently,
it lacks the Debian amd64's convenience of providing multiple
bootable kernel versions at the same time.
Of course, I am always interested in means of reducing external
dependencies, i.e. replacing the bootloader (currently from armbian)
and kernel-upgrade script (currently “homegrown“) with “proper“ Debian
solutions. I dream of generating a bootable image from just a single
regular Debian mirror... :)
Additionally, I can tell that the new `mmdebstrap` really pays off
in terms of speed and less workarounds needed. It is, however, a little
difficult to get started (cf. linked debian-user thread) and I might
manage to reproduce the a bug regarding the use of mode `fakechroot` on
Debian stable (to be continued...)
In case you are interested in my scripts, they are all published on
