Hello,

please direct questions to the barebox mailing list (CCed), there are
more people there who can answer you :-)

Unfortunately the documentation was updated before the respective patch
series was merged. If you pull the branch v2018.04.0/topic/rpi from
git://git.pengutronix.de/rhi/barebox, you should get a
barebox-raspberry-pi-3.img. (I think that branch should also be able to
be rebased onto the current master, but I have not tested that.)

The rest of your steps below look fine to me.

FWIW, the series is based on barebox v2018.04.0. I tried rebasing (already a 
few weeks ago), but it does not even rebase cleanly on top of v2018.05.0.

I've already rebased this series on top of the current release. Just
waiting for some test results before sending out to the list again.

Issues compiling barebox on raspberry pi

[Kai Che]

Hello,

I'm trying to compile barebox on the raspberry pi 3 model B and after booting the pi with the barebox-raspberry-pi-3.img I get the following error:

barebox 2018.04.0-g9b6b12471 #2 Thu Oct 18 14:33:09 CEST 2018

The pi doesn't accept any keyboard input and is "stuck" at this stage.

How and where can I get the barebox.env file?

Thanks very much and best regards,

Kai Che
