OPi 5 plus not booting

Tanamir

Hello, I have an OrangePi 5 plus (32Gb) that doesn't want to boot from the TF card slot. When I use the RK Dev tool (3.15) to install the OS to the TF card, everything is OK according to the tool, but the TF card fails to boot. I go through all the steps exactly the way it is laid out in the User Guide and the Dev tool said that the OS installed correctly, but when I take the TF card and examine it using Windows Disk Management tool, the card shows up as a RAW disk. No data, not formatted. I started with a 32Gb TF card that was formatted in FAT32. I have repeated this procedure a hundred times and it is the same every time. THE RK DEV TOOL DOESN'T WORK to write to the TF card. Can someone help me with this problem? I also have several 128Gb cards that I would like to use, but the format is not FAT32, it is ExFAT, and I have had no luck writing to any of my 128Gb cards at all. There is nothing in the user manual that states that you HAVE to use FAT32, but I stand to be corrected. I have also tried using the RockChip upgrade disk tool v 1.72 to write to the TF card, but that has had limited success as well, with only Opi OS (OH) installing to the card and it doesn't boot with the OPi 5 plus 32Gb unit at all. I am trying to diagnose the issues with this board and I have had ZERO success so far with this board. Very frustrating.
