Hi, For some reason, I'm not getting a signal via HDMI when running the bullseye installer from the prepared SD card images. I thought this might be a monitor issue, but booting a microSD card with the manufacturer's image shows that this is not the case.
Any ideas what could be going on? There's an eMMC attached, but knowing that it might affect the boot process, I have zeroed it out. I'm doubtful that it's the installer. Yesterday, I finished an installation on a RockPro64, a similar platform, without issues. I'd attach a serial cable but the Rock Pi 4 requires on capable of 1.5Mbps and none of my cables are. I thought I'd ask here before purchasing one. Best, Christian
