Pengutronix installation and setup

Hi all, 
I have got the following source and installed ptx using
OSELAS.BSP-Pengutronix-Mini2440-Quickstart document.
 
OSELAS.BSP-Pengutronix-Mini2440-2012.06.0.tgz
ptxdist-2012.07.0.tar.bz2
OSELAS.Toolchain-2011.11.1.tar.bz2

can you plz help with how to start with Pengutronix, i mean to create
kernel and rootfs images. a step by step guide or online link wud be help
full. i also
http://wingston.workshopindia.com/wingz/embedded-programming-on-the-mini...
but that link is not alive. so plz help me on d same.

Regards,
Dhruv

Something wrong with the quickstart? It describes all the steps from
downloading the archives, installing required software, building the board
support package (BSP) and how to deploy your Mini2440 with the result. What
else do you need to know?

Once i am done withe the following with no error
 # mkdir ~/local
 # cd ~/local
 # tar jxvf ptxdist-2011.11.0.tar.bz2
 # cd ptxdist-2011.1.0
 # ./configure
 # make
 # sudo make install

on passing the below command i get the following error

$ ptxdist platformconfig
error:  'selected_ptxconfig' file is missing
  try 'ptxdist select <ptxconfig>' or
  'ptxdist clone <project>' to clone an existing project

You just installed PTXdist. Its a tool to be able to build all the other
components to make your target work.
Now you should begin with the next step: Extract the compiler toolchain
archive at a different location, configure it for your target architecture
and continue. To build it you need the already installed PTXdist.
After you have PTXdist and the compiler toolchain in place (mostly a
one-time-job), extract the Mini2440 BSP and this time use the compiler
toolchain and PTXdist to build it.

Thanks for the information Juergen :) and can we modify the kernel config
using PTXdist, the way be do using make menuconfig.

Sure. You can modify *everything*. In your case run ptxdist "menuconfig
kernel"

I was installing the pengutronix BSP according to the quickstart manual.
While configuring the ptxdist with the command:
$./configure

I get an error as:
configure:error:Please specify the location of the patch executable with
the option '--with-patch'

What location am I supposed to give here ?

Install the "patch" command line tool.

Thanks Juergen
I just wrote "sudo apt-get install patch" and it's done.

I execute follow commands:
mkdir ~/local
cd ~/local
tar jxvf ptxdist-2014.07.0.tar.bz2
cd ptxdist-2014.07.0
./configure
make
sudo make install

After this, i execute follow commands:
mkdir /opt/OSELAS.Toolchain-2012.12.1
chown silart /opt/OSELAS.Toolchain-2012.12.1
chmod a+rwx /opt/OSELAS.Toolchain-2012.12.1.

And:
$ tar xf OSELAS.Toolchain-2012.12.1.tar.bz2
$ cd OSELAS.Toolchain-2012.12.1
$ ptxdist select
ptxconfigs/arm-v4t-linux-gnueabi_gcc-4.7.2_glibc-2.16.0_binutils-2.22_kernel-3.6
-sanitized.ptxconfig

After last command i receive next error:
error:  'selected_ptxconfig' file is missing
  try 'ptxdist select <ptxconfig>' or
  'ptxdist clone <project>' to clone an existing project

What is my fault?

You must build the toolchain with the corresponding ptxdist-2012.12.0.

Juergen, text from my previous post, I copy from manual. I use
OSELAS.Toolchain-2013.12.2.

This error occurs in ptxdist-2014.08.0 and ptxdist-2014.07.0 versions. I
build ptxdist-2014.06.0 and all is ok.
Command:
ptxdist setup
is executed successfully.

When i execute this command in ptxdist-2014.08.0 or ptxdist-2014.07.0
versions, error occurred.

Is it bug or feature?

You must build the toolchain with the corresponding ptxdist-2012.12.0.

sudhakar_G,

sorry, no idea yet. Its not PTXdist which fails in your case, its the
autotools based build system of the glibc. Can you have a look into the
"platform-arm-v4t-linux-gnueabi-gcc-4.7.2-glibc-2.16.0-binutils-2.22-kernel
-3.6-sanitized/logfile"?
We (Pengutronix) have a dedicated mailing list for such questions, where
you should send this logfile to. Otherwise I habe no idea how to get an
idea what going wrong at your side.
