Raspberry Pi3B+ has been working for me for a long time along with industrial equipment. Specific programs have been developed. Now we need to run this SD card with all the configured programs to Raspberry Pi4.
The Pi4 does not boot with this SD card...
I understand that the PI4 uses a different chipset and added the bcm2711-rpi-4-b.dtb file to the boot directory. But it didn't help: the green LED flashes 4 long + 4 short flashes. This is clearly some kind of error message.
What additional steps do I need to do to run the Pi3B+ image on Pi4?
