Thanks for the reply!

Hello,

I am new to the world of ptxdist and firmware image building. To get my fee= t 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/201= 7-08-28-distrokit-a-playground-bsp-for-ptxdist.html>).

The image for rpi2 is successfully built but I am unable to get the image w= orking on my rpi2. Nothing happens after the gpu firmware has booted and us= ing serial to usb connector gives nothing but radio silence so I am guessin= g 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 messa= ges, and then some systemd startup messages, followed by a login prompt. Ho= wever, 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 b= ug by copy /boot/zImage from the second partition on the SD card to the boo= t partition, and changing "kernel=3Dbarebox.bin" to "kernel= =3DzImage" in config.txt.

I found the following github repo (https://github.com/= rohieb/DistroKit-rpi-ibrdtn <https://githu= b.com/rohieb/DistroKit-rpi-ibrdtn>) which seemed aimed at distr= okit and rpi images so I tried to build an image with it instead and manage= d 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 o= fficial DistroKit Git repo. Back then, I only had access to a RPi1, so I us= ed platform-rpi. Also, this was before platform-rpi and platform-v7a was re= cently 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. R= Pi 3 should in theory also work with platform-v7a, but I think no one has c= ome around yet to testing that...
