Hello,
I am new to the world of ptxdist and firmware image building. To get my
feet wet I have tried to build an image for my raspberry pi 2 with
ptxdist and distrokit following the blog post on the pengutronix
homepage
(http://pengutronix.de/en/2017-08-28-distrokit-a-playground-bsp-for-ptxdist.html
<http://pengutronix.de/en/2017-08-28-distrokit-a-playground-bsp-for-ptxdist.html>).
The image for rpi2 is successfully built but I am unable to get the
image working on my rpi2. Nothing happens after the gpu firmware has
booted and using serial to usb connector gives nothing but radio silence
so I am guessing that the kernel is not booting at all. I have tried
several sd cards and another rpi2 so I have ruled out faulty hardware. I
also tried building an image for rpi1 but it didn't work as well.
I just tried it out, and you're right. We should see some barebox
messages, and then some systemd startup messages, followed by a login
prompt. However, the system does not even seem to start the barebox
bootloader.
I'm not sure how to debug this, but you could try to work-around this
bug by copy /boot/zImage from the second partition on the SD card to the
boot partition, and changing "kernel=barebox.bin" to "kernel=zImage" in
config.txt.
I found the following github repo
(https://github.com/rohieb/DistroKit-rpi-ibrdtn
<https://github.com/rohieb/DistroKit-rpi-ibrdtn>) which seemed aimed at
distrokit and rpi images so I tried to build an image with it instead
and managed to get an image that actually boots on my rpi2.
This is one of my old repos which I used as a playground for DistroKit
when working on my master's thesis. It is a fork of an old version of
the official DistroKit Git repo. Back then, I only had access to a RPi1,
so I used platform-rpi. Also, this was before platform-rpi and
platform-v7a was recently overhauled in DistroKit in July.
What is the official status of the distrokit support for raspberry pi?
RPi 1 should work with platform-rpi, RPi 2 should work with
platform-v7a. RPi 3 should in theory also work with platform-v7a, but I
think no one has come around yet to testing that...
