arm rock64 user

Hi Igor, I have Rock64 Ver.2 - 1gb model. Please let me know what is yours? Ver. 2 or 3?

I don't have that USB serial adapter + cable.

I have Rock64 Ver.2 - 1gb model. Was working fine with Armbian 24.5.0-trunk.211_Rock64_bookworm_current_6.6.21 - boot from micro SD card On SSH, I updated to latest version Armbian_25.2.1_Rock64_bookworm_current_6.12.13. Now it does not boot from micro SD card. I had another micro sd card. I flashed new Armbian_25.2.1_Rock64_bookworm_current_6.12.13 - does not boot. I had another micro sd card. I flashed OLD Armbian 24.5.0-trunk.211_Rock64_bookworm_current_6.6.21 - it boots. Then updated to latest Armbian & does not boot anymore. Looks like some " Flashing_u-boot_to_SPI_Flash " - problem. Please help. Thanks in advanced
