So we have used over 300 Solidrun Cubox-i (model: I2EXW-300) and now Cubox-M for the first time. The first thing I don’t understand is that the sticker doesn’t say what model it is. We have bought the 1GB and 4GB version and they are not distinguishable externally.
I have loaded the images from SolidRun Images and copied them to the Micro SD card. No device could be started. I have tried Debian and Android but neither works. However, I was able to find that with Power over Ethernet the image “sr-imx8-debian-bullseye-20210621-cli-imx8mp-sdhc-cubox-pulse.img” starts and I can log in via SSH. On the HDMI port I have no picture or signal. I tried 8 different models in the process. On the old models there was an OTG interface with which you had a serial console. This interface if it is present on this model does not work for me.
