Hi all,
My board is the 4GB commercial version of Cubie A5E.
I have already tested with multiple official images, all without success:
• Official Cubie A5E Bullseye XFCE Beta v1
Downloaded from:
https://github.com/cubie-image/sun55iw3p1/releases/download/beta_v1/cubie_a5e_bullseye_xfce_beta_v1.rawdisk.img.gz
• Official Radxa KDE version
Downloaded from:
https://github.com/radxa-build/radxa-cubie-a5e/releases/ (radxa-cubie-a5e_bullseye_kde_b1.output_512.img.xz)
• Armbian images
Downloaded from:
https://www.armbian.com/radxa-cubie-a5e/
All of them fail in exactly the same way:
• Only solid green LED, no UART output at all (tested with multiple USB–TTL adapters at 115200 8N1).
• Tried several A1-rated SD cards (SanDisk / ADATA / Kingston).
• Power supply is 5V 5A, also tested with other adapters.
• Tried different HDMI cables and displays (including HDMI capture card).
• The board shows no reaction, it (only seems to enter FEL mode???) and never boots from SD.
• No visible reaction.
• Tried different image writing methods (PhoenixCard, dd, Etcher, Rufus) on different host systems – result is always the same.
At this point I’m unsure what else to try.
Has anyone successfully booted these images on the Cubie A5E?
Any suggestions for additional troubleshooting steps would be greatly appreciated.
Thanks in advance.
