Petalinux Header Files 4.19.0-xilinx-v2019.2

[ainam.]

We are working on the TE0701-06 boards with Ubuntu 18.04.4 LTS.

We need to write driver code and have had problems finding the header files to build them.

The version we need is 4.19.0-xilinx-v2019.2.

The device is connected to the internet but it can't find that version. Trying to find it manually was also not succesful. Please where can we find those header files?
Alternatively how can we build the image with those header files already in them?

Thank you.

Hi,
you must check Xilinx git:
https://www.xilinx.com/support/answers/75775.html
--> git://github.com/Xilinx/linux-xlnx.git

I have followed that git repo:

sudo apt-get install libssl-dev fakeroot
git clone https://github.com/Xilinx/linux-xlnx
cd linux-xlnx
git checkout xlnx_rebase_v4.19_2019.2
(copy the .config from PetaLinux here)
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- deb-pkg # For Zynq UltraScale

but at this point I get this:



Makefile:595: include/config/auto.conf: No such file or directory
  YACC    scripts/kconfig/zconf.tab.c
/bin/sh: 1: bison: not found
scripts/Makefile.lib:196: recipe for target 'scripts/kconfig/zconf.tab.c' failed

make[1]: *** [syncconfig] Error 2
Makefile:635: recipe for target 'include/config/auto.conf' failed
make: *** [include/config/auto.conf] Error 2


I couldn't continue.

Hi,
sorry we use petalinux flow only.
I can't help with the steps to generate all by yourself with own make files. Maybe you should write to Xilinx forum.

I would also be interested in that. Can you tell me how to do it in Petalinux?

I am just looking for a way to install the header files to make driver code. I have been stuck here and even the Xilinx forum doesn't provide any support, so can any solution would do.

Hi,
please check:

https://wiki.trenz-electronic.de/display/PD/PetaLinux+KICKstart#PetaLinuxKICKstart-PetaLinux2019.2

Which module did you use on TE0701? We provide reference design on our download area.

Can you point me to the reference design please? I think it would be better to use that out and then adapt the OS to our needs afterwards.

[JH]

Which Module did you use? TE0701 is a carrier only. We have different compatible modules:

Thank you for your reply.

I have been successful in making a Petalinux but when I try to configure the Kernel I get this error message:

Code: [Select]

Hi,
which version did you use? Did you installed all necessary packages for petalinux? Do you have the necessary requirements on your machine?

[ainam.]

I followed the Manual exactly. PetaLinux Installer.

I think you might be on to something the requirements are fulfilled but I think some packages might be missing. Let me check.

Thank you for answering so quickly. Please don't go too far away

Hi,

which OS did you use? How many RAM and CPU kernel did you use?
Which additional linux packages did you install?
I can't reproduce this issue on my VM.

I've found some forum post where someone has the same problem:

umask should be set to 0002

just do:

>umask 0002

and then

>petalinux-config -c kernel

again and it should work.
