[ELDK] eldk-switch.sh has no effect

Mon Sep 2 09:34:08 CEST 2013

Hi all,

this is my very first post on a mailing list, ever. I hope I'm doing everything the right way.

Okay, I visited an Altera SoC FPGA Workshop organized by EBV some weeks ago.
During that workshop we were introduced to the Denx ELDK. Now, that I have some time on a buisness trip, I try to work with the ELDK.

I use ELDK version 5.4 and I'm targeting the ARM armv7a-hf architecture. I would like to test everything with a QEMU Emulator which I succesfully installed and tested on a Debian Linux which runs in a Virtual Box on my Windows XP computer.
Puh, what a setup . . . 

I downloaded everything which I think I need according to the documentation on that site: http://www.denx.de/wiki/ELDK-5/WebHome

The installation with the install.sh script worked out fine.

The installation of the eldk-switch tool worked out fine.

Next thing I tried was to use eldk-switch.sh to set the toolchain to the cross compiler for the target. Here, I got some problems. Please read the outcome of the eldk-switch command (at the end of this log you can also find the information about the Debian version I am using):

So the problem is (as you might see) that the command "eldk-switch -r 5.4 -v armv7a-hf" is doing a lot of stuff but in the end, the command "eldk-switch -q" reveals that actual nothing happened.

Why is that so? What could be the cause for this?

As you can see, I'm root. So the environments should just be set correctly, shouldn't they?

Maik
