Hi Kel, A v2 was posted about a week ago. The contents in rk3588s-orangepi-5-pro-u-boot.dtsi which is in linux-next for 7.4 fixed the PCIe hang for me and is designed to address what you describe. V2 does not have PREBOOT enabled. Thanks for the feedback. I would like to understand if the dtsi changes are not working on your board. I have a pair of 16GiB boards and both work for me.
