Hello,
In our projects we would use the HDMI of the revPi.
I would like to disable the original boot up screen - the raspberries and the loading text with a picture. I tried some advices which shpuld works in raspberry pi but it soesnt seems to work in RevPi.
Can you please advice what is the best way to replace to boot process with a picture?

Hello Ivan,

could you explain what you have tried so far? Do you have links, code or anything else to it?

Do I understand you correctly? You want to disable the home screen with the raspberries on top, instead you want to show another image/logo of the company or something else?

Best regards,

Johannes

Hello,

I'm facing the same issue. I made some progress that might help you a bit.

I followed the steps found on this site:
https://scribles.net/customizing-boot-u ... pberry-pi/

All the boot text disappeared, except for two lines:
[ 0.000000] [Firmware Bug]: Bootloader left irq enabled: bank 1 irq9
[ 3.259332] piControl: kernel_read returned 0: b844d400, 11126

And my own start-up picture appears for only 1 sec.
For the rest, the screen is pitch black.

Still I'm not happy:
- the remaining two lines should go away too
- it would be nice to have my own start-up picture on the screen for a longer time.

Any tips are very welcome.
Best regards,
Alexander.

You completely undestand what I need.
I tested already this list of changes https://scribles.net/customizing-boot-u ... pberry-pi/ I manage to hide most of the boot up screens but the unit still show the code and raspberries for some 5-6 seconds on boot up.

Hi @ all,

I did pretty much the same things as this link describes and got the same result as Alexander.
I will test it again next week and see if we can make the remaining lines disappear as well.
And if it is possible to increase the time of the splashscreen.

Best regards
Johannes

Ivan,

If you still get the raspberry icons, you might have done the same thing I did wrong the first time.
There is an important line on that page:
Remove other things
Still in “/boot/cmdline.txt”, add below at the end of the line

Make sure in cmdline.txt there are no linefeeds. In other words: it has to be one long line.

Best regards,
Alexander.

Thank you. Correct! when I inserted it on the same line it worked.
Now it only shows the 2 lines of code during boot up.
I also manage to change the desktop with my custom image with a big text "Loading".
After the browser starts in qiosk mode - it works fine.

Still looking for a solution to replace the whole process with a single picture - like in the HMI
