Orange Pi RV2 no boot with SD card and official images

Lateralux

I am experiencing a serious problem with my new orange Pi RV2.

I have downloaded all the official images (ubuntu dekstop, ubuntu server and openwrt) from the official repo.
I flashed them properly to a high-quality, speed compatible TF card, with BalenaEtcher, following the official documentation


However, when I power on the board with the card inserted, I get only the red power LED and a black screen. There is no boot activity. RJ45 ethernet is blinking but i got no dhcp assigned ip.
Oddly, when I power it on without an SD card, the green led is active and I do see the bootloader waiting screen on my monitor — which suggests that the HDMI output and the Pi works fine.
Power adapter is ok, an official one from the store.



I've tried all official Orange Pï RV2 images, burned them with BalenaEtcher. Checksums are ok.


I noticed there is no bootflag on the partition and the partition table has 30Mo of empty space at the beginning. Strange.
If i manually add the boot flag, nothing changes, same problem.


I haven't got any serial port adaptater tools to debug more.


I'm very disapointing, the hardware seems very nice, i did not expected so much difficulties.
Thanks for your support
