Libre Raspbian Image Won't Boot (roc-rk3328-cc)

Hi all - Looking for help getting Raspian to boot on my Renegade.

  1. Downloaded 2023-05-03-raspbian-bullseye-arm64+roc-rk3328-cc.img
  2. Burned image to 128GB SD card using Raspberry Pi Imager.
  3. Inserted SD card, recycled power, will not boot.

Via serial debug I see the following:

Any suggestions as to what I am doing wrong? TIA to all.

What is the make and model of the display you have?

Thank you for the reply. Samsung, U28e510D.

You were right :slight_smile: - I disconnected the display from the HDMI port and got further - I can now ping the device, but am not seeing a login on the serial debug, nor have I been successful using ssh to connect to the IP. Sorry for the newbie questions, I am trying to utilize Libre images to make better use of the device. Thanks again for the assistance.

After booting a Libre image, what is the recommended way to connect via serial debug or eth?

Serial is enabled only as part of the bootloader stage. To have it working in the Linux stage, you need to run sudo ldto merge uart2 and reboot. For SSH, use the normal operating system method.
