I use dd to copy my images and always use the symlink as if arg

Matthijs ter Woord

@mterwoord

@Carton32 I usually have the with and without timestamp ones which are exactly same

in his case he has <timestamp>.rootfs.img and cm3.rpi-sdimg

those are same? that would mean rootfs actually contains more than just the 1 fs..

would be weird, imo..

@thesillywhat

Also what are the advantages of using boot2qt then using yocto with qt5 layer for raspberry pi. Is the answer as simple as boot2qt is more designed for system using qt applications

thesillywhat

@thesillywhat

@Carton32 Have you tried creating raspberrypi image with Qt5 layer

So I downloaded the qt5 meta layer added that in bblayer.conf. Now all I have to do is run init script and bitbake command to make a qt5 image

Is this right?

bitbake qt5-image

Carton32

@Carton32

Yes I have an application that runs on eglfs (single window app)

What kind of Qt5 app do you have ?

I never tried the qt5-image

thesillywhat

@thesillywhat

I have an application that runs on xcb and eflfs

on either xcb or eglfs

so how did you proceed with it

am i atleast right on the bblayer.conf stuff ?

thesillywhat

@thesillywhat

@agherzan Whats the difference between setting the Machine value to Raspberrypi3 and raspberrypi-cm3.
The reason behind this question is that.

I had a image file that I downloaded from the raspberrypi website. I was able to use the same image file on raspberrypi 3B+ and on the compute module with a little change to the config.txt

And Can I do same with the generated yocto images?

Andrei Gherzan

@agherzan

@thesillywhat we currently don't support that. That is done by having multiple kernels in the boot partition and fw loading the right now.

I am looking into having this for rpi4-64 and rpi3-64 in the near future.

But right now each board has its own machine.

thesillywhat

@thesillywhat

@agherzan understood. Thanks

thesillywhat

@thesillywhat

Is it possible to change the raspberry-pi image.. It appears during bootup with a progress bar in front of it

Carton32

@Carton32

Yes with psplash receipe

I can help you tomorrow for qt (at least the best I can)

thesillywhat

@thesillywhat

@Carton32 thanks

thesillywhat

@thesillywhat

Where is this make image script located

thesillywhat

@thesillywhat

nevermind found it

Carton32

@Carton32

@thesillywhat I can give you what I did to run my eglfs app on raspberrypi3 machine. Telle me when you're wake xD

Matthijs ter Woord

@mterwoord

regarding psplash: how would i change the image: bbappend a different constant?

any samples of files doing so?

Carton32

@Carton32

FILESEXTRAPATHS_prepend := "${THISDIR}/files:"

SPLASH_IMAGES = " file://psplash-mysplash.png;outsuffix=default"
ALTERNATIVE_PRIORITY_psplash-default[psplash] = "999"
INITSCRIPT_PARAMS = "start 5 S . stop 20 0 1 6 ."

I don't know if the syntax is 100% correct (in particular with the init parameters) but it works

This is in my own layer in a recipes-core/psplash/psplash_%.bbappend

and the image is in recipes-core/psplash/files/

Matthijs ter Woord

@mterwoord

@Carton32 Awesome! Thanks

Is that a full-screen splash?

Carton32

@Carton32

yes

Matthijs ter Woord

@mterwoord

Any weird things related to resolution or format of the png?

Carton32

@Carton32

The resolution of my PNG is 427x427px with a transparent background

Matthijs ter Woord

@mterwoord

And I'm guessing the image then is centered?

Carton32

@Carton32

yes

Try with a "dummy" picture to see the result

Matthijs ter Woord

@mterwoord

yeah. But having a bit more info upfront helps a lot! Thanks!

Carton32

@Carton32

thesillywhat

@thesillywhat

@Carton32 I am now... Or If you want we can do this tomorrow on Saturday... I am on EST but I should be available all day

@agherzan Can't we merge the psplash repo with this repo

Carton32

@Carton32

I will try but I usually do this at work. Remind me tomorrow and if I'm still at home, it's ok

thesillywhat

@thesillywhat

okay..
