Hi and Thank @jock That's what I thought. I used ledconf-3 because that's the configuration you made specifically for my MX10 box. I ran a memtest, which went smoothly. The system is working, and I was able to compile rockchip mpp without any problems. The system is running Bookworm. Would it be better to update to Trixie or revert to a previous version? What do you think? I think the problem comes either from rk3318-box.dtb or from the overlays. Thanks again. 🤜🤛

Hi @kazekami_him, Thanks for your information, but I have no idea in how to use this content for test it. Maybe @Nick A Could understand what this guy did and how to bring it to his port and help us to detect the correct ram amount.

@jock well thanks but I already figured that part out 😊 my problem right now is that i can't find a single distro that works with my box . almost every one (even multitool) goes to a black screen and freezes excatly after 60 seconds . the best thing i could find was a android rom that have the same problem but in excatly 30 minute after booting up ! i did this stupid thing that did not backed up my original rom before writing to internal emcp flash 🤦‍♂️ if i can find any version that doesn't have this problem , i know how to merge armbian rootfs with it ! thank you again !

Have you tried your python script with your Linux PC? If it happens again, you can tell that the problem is within the ESP32 program. I generally prefer having the most complex system (Armbian) poll the simplest device (ESP32), instead of the ESP32 interrupting the Armbian system. I found it more stable that way. Stay with wifi, and use the ESP32 serial port just for debugging. Program the ESP32 print an acknowledgement of data requests, and an alarm if it gets stuck in an unexpected state. I have also found ESP32 circuit or micro python very stable for serial port communications.

I do not have any other monitor available but I did order a UART to usb device, and I have identified with a multimeter the uart pads, which are next to the SD card slot. I will keep this feed updated!
