Boot2Qt on raspberry pi 0 wifi

[davidino]

Goodmorning to all,
I write you since I have correctly used boot2qt for crosscompile qt for raspberry pi 3, but I don't find raspberry pi zero among the available MACHINE.
Can you suggest me the needed modification for including raspberry pi 0 wifi board?
Thank you.

Hi,

Not a direct answer but you should compare the various raspberry pi mkspecs and their corresponding devices. Then you might be able to deduce what modifications you may have to make.

Hi,
use meta-raspberry support, you can add machine raspberrypi0-wifi.conf to your meta-layer
https://git.yoctoproject.org/cgit/cgit.cgi/meta-raspberrypi/tree/conf/machine?h=rocko

Hello to all, thank you for your answer.
Looking in the meta-boot2qt folders I found that there is already the file indicated, in meta-boot2qt/sources/meta-raspberrypi/conf/machine/raspberrypi0-wifi.conf.

Instead in the folder meta-boot2qt/meta-boot2qt-distro/conf/distro/include, there are listed all the supported boards and I added a file named raspberrypi0-wifi.conf ( exact copy of raspberrypi.conf of the same folder), but unsuccessfully; when I export MACHINE=raspberrypi0-wifi.conf the MACHINE is not recognize.

When you say to add raspberrypi0-wifi.conf, in which folder do you mean to add it?
Thank you.

@davidino said in Boot2Qt on raspberry pi 0 wifi:

export MACHINE=raspberrypi0-wifi.conf

If the file already exists you do not need to add it again.

Try this:
export MACHINE=raspberrypi0-wifi

Hello Cleiton Bueno,
thank you for your message. I miswrote the export MACHINE command, copying and paste. I always do write export MACHINE=raspberrypi0-wifi. In figure 1, the command sequence that I use:

The content of meta-boot2qt/meta-boot2qt-distro/conf/distro/include is shown on picture2.

The content of meta-boot2qt/sources/meta-raspberrypi/conf/machine/ is shown in figure3.

Today I modified the script source-environment,sh adding raspberrypi0-wifi as follow, and the result changes a little:

    ;;
    raspberrypi0|raspberrypi0-wifi|raspberrypi|raspberrypi2|raspberrypi3)
      LAYERSCONF="bblayers.conf.rpi.sample"
    ;;

and I get the following errors:

How that Qt staff didn't provide a tutorial for adding custom boards to their repository?
Have you got any ideas?
Thank you for your attention.

Why not use raspberrypi0, it's practically the same.

Look at meta-raspberrypi, raspberrypi0-wifi.conf is the merging of raspberrypi0.conf with raspberrypi.conf

https://git.yoctoproject.org/cgit.cgi/meta-raspberrypi/tree/conf/machine?h=rocko

So use raspberrypi0 and customize the packages you need for WiFi as well as device-tree.

Hello,
I think that the problem has been as follow:

• As suggested by @Cleiton-Bueno, inside meta-boot2qt/meta-boot2qt-distro/conf/distro/include, I've made a copy of raspberrypi0.conf, renaming it as raspberrypi0-wifi.

• Modify source-environment.sh and b2qt-init-build-env scripts, adding raspberrypi0-wifi among the available machine.

• Remove the package VALGRIND from the recipe packagegroup-b2qt-embedded-tools.bb contained in the folder /home/davide/meta-boot2qt/meta-boot2qt-distro/recipes-core/packagegroups**
  Reading in internet, I found out that valgrind package is not compatible with both raspberrypi1, raspberrypi0, raspberrypi0-wifi.

After that, it worked correctly.
Thank you for your support.
