problem with zybo: Can not compile u-boot

[cto@qlt]

I followed this tutorial: https://www.instructables.com/id/Embedded-Linux-Tutorial-Zybo/

but now I'm stuck,

when I enter: make CROSS_COMPILE=arm-xilinx-linux-gnueabi-zynq_ZYBO_config

I get the error: System not configured - see README
I have no idea why that occurs, I'm using ubuntu 16 with Vivado Web+SDK 16.4 its a new VM so I have only the xilinx software installed, do i need to install anything else may be?

Hey cto@qlt

The problem is very likely a missing space in your command:

make CROSS_COMPILE=arm-xilinx-linux-gnueabi-zynq_ZYBO_config

This should actually be:

make CROSS_COMPILE=arm-xilinx-linux-gnueabi- zynq_zybo_config

Also note that lower and upper case is important on Unix/Linux systems.

Hope it helps,

That solved that issue.

now I have a new one:

user@ubuntu:~/DIGILENT_LINUX/u-boot-Digilent-Dev$ make CROSS_COMPILE=arm-xilinx-linux-gnueabi- zynq_zybo_config
Configuring for zynq_zybo board...

but the fiel is there:

its listed, and the file has execute permission, but when I try to execute it i get the no such file error wtf :/

any ideas how that happens?

cto@qlt  If it solved the issue, it is correct etiquette to give @hpoetzl the solution, then open a new request. That will keep new answers coming fast your way. 

Just a few of the respondents here are Xilinx employees. Mostly are here just for the dopamine kick of a kudos and solutions accepted (my case anyway).

Keep that in mind.

Hey cto@qlt

The executable in question is a dynamically linked binary, which means that it depends on some libraries.

If one of the libraries is missing, you will get 'No such file or directory'.

Double check the library dependencies with:

ldd /opt/Xilinx/SDK/2016.4/gnu/arm/lin/bin/arm-xilinx-linux-gnueabi-gcc

And see if the listed libraries are properly configured.

Hope this helps,

Herbert

@ubuntu:~/DIGILENT_LINUX/u-boot-Digilent-Dev$ ldd /opt/Xilinx/SDK/2016.4/gnu/arm/lin/bin/arm-xilinx-linux-gnueabi-gcc
	not a dynamic executable

wtf?

should I install the xilinx software again or what else should I try?

I have also an other problem i cant start the SDK, when I go on start SDK nothing happens

[hbucher]

cto@qlt  Can you do a 

file /opt/Xilinx/SDK/2016.4/gnu/arm/lin/bin/arm-xilinx-linux-gnueabi-gcc

In my install it is a ELF 32-bit LSB executable, dynamically linked.

[cto@qlt]

Ah its 32 bit, that explains a lot...

after installing support for 32 bit executables the build process works Thanks :-)
