Now I wanted to write a file to the second sd card. To do this I pressed the power button and waited until the LEDs were off. Then I took out the sd card and wrote the file to the card. After I put the sd card back in, I pressed the power button again. But the malfunction described above happened again. Let’s see what I have to try again to get the Dreamcatcher working again. This has nothing to do with a stable system!
A power button should shut down a system properly and not bring it into an undefined state!
