For Image-69 you need to update/install/upgrade to the latest SPL and U-Boot binaries in your boards FLASH first.
The easiest way to do that would probably be with the v2.8.0 sdcard.img from https://github.com/starfive-tech/VisionFive2/releases/tag/VF2_v2.8.0
And following the relevant section of the QSG (Quick Start Guide) for updating the SPL and U-Boot.
Once you have done, which you say you have, then you might, depending on your monitor, hit a display problem, see this thread - “unified reply to a question about the display of debian69”.
For more help you really do need to be clearer than “I still cannot boot”, that does not help to narrow things down. If you disconnect the monitor and power up the board and leave it for say 5 minutes do the LED’s on the network port light up if you connect a cable. Do you have a 3.3 volt usb-ttl serial cable (or a RPi and 3 wires to use as a serial debugger).
