Just managed to distract myself some more in this outrageous heat here in the UK and can confirm that the RELEASE=stable (6.18) build (from compile.sh) boots ok after some tweaking.  It got stuck on "Starting Kernel" but when I added these lines to /boot/armbianEnv.txt to see why it failed, then it booted ok - dunno why.  I think keep_bootcon was the important bit.

 
extraargs=earlycon=uart8250,mmio32,0x02500000 keep_bootcon ignore_loglevel loglevel=8  
The other problem then was getting the ethernet to work which I did by creating a device tree overlay file - much the same as other here is it only seems be working at 100M unlike the 1000M in the 5.15 kernel.  The extra problem seemed to be that the wifi driver would periodically crash and cause a kernel-panic.  The following DTS file pulls the ethernet down  to 100M and disables the wifi to stop it crashing.  You then compile this into a .dtbo file, copy it to /boot/overlay-user and reference it in armbianEnv.txt with this line 
 
user_overlays=opi4a-network-fix
 
The opi4a-network-fix.dts syntax to create it is as follows ... apart from that I can't get it to do much more, so will go down the 5.15 bookworm route until things change
 
/dts-v1/; /plugin/; / {    compatible = "xunlong,orangepi-4a", "allwinner,sun55i-t527";    /* Maintain working Ethernet at 100M address 1 */    fragment@0 {        target-path = "/soc/ethernet@4510000";        __overlay__ {            phy-mode = "rgmii-id";            phy-handle = <&ext_rgmii_phy>;            status = "okay";            mdio {                #address-cells = <1>;                #size-cells = <0>;                ext_rgmii_phy: ethernet-phy@1 {                    compatible = "ethernet-phy-ieee802.3-c22";                    reg = <1>;                    max-speed = <100>;                };            };        };    };    /* Hard disable the unstable wireless MMC controller block */    fragment@1 {        target-path = "/soc/mmc@4021000";        __overlay__ {            status = "disabled";        };    }; };

 

After upgrade to 7.0.0-rc6-edge-sunxi64 wlan is shown in interfaces. Gigabit Ethernet does not work yet.
