NanoPC-T6 is a ultimate device than R4S R5S R6S

Hello,
I tried to build a new openwrt image starting from @mj82's repository 6.8 image branch, but all I get is a solid red light for SYS. Any help would be greatly appreciated as I have no idea what I am doing here .

I used the following changes:

rockchip: add FriendlyElec NanoPC T6

And these are the steps that I attempted:
Built the image:

• used make menuconfig to select the new NanoPC T6
• Build the image using make

Applied the image

1. Piggy back on FriendlyWRT

• Flashed the FriendlyELEC 23.05 image using their instructions:
  https://wiki.friendlyelec.com/wiki/index.php/NanoPC-T6#Flash_Official_OS_to_eMMC
  Specifically rk3588-eflasher-friendlywrt-23.05-20231201.img.gz from 01_Official images -> 02_SD-to-eMMC images here:
  https://drive.google.com/file/d/1SFbJLgS6hbskl-9cM7SwBBQu1JYB7oUg/view?usp=drive_link
• Used the UI to flash the OpenWRT image generated at the previous step openwrt-rockchip-armv8-friendlyelec_nanopc-t6-ext4-sysupgrade.img.gz
  Result:
• Solid red light; no boot from emmc; no boot from microSD; Needed to do recovery using USB install from a PC

2. Direct install

• On the eflasher MicroSD created earlier I added the openwrt-rockchip-armv8-friendlyelec_nanopc-t6-ext4-sysupgrade.img.gz`
• In eflasher.conf changed autoStart=rk3588-eflasher-friendlywrt-23.05-20231201.img.gz as per instructions at: https://wiki.friendlyelec.com/wiki/index.php/NanoPC-T6#Flash_third_party_OS_.28Image_file.29_to_eMMC
  Result:
  As before: Solid red light; no boot from emmc; no boot from microSD; Needed to do recovery using USB install from a PC

Recovery using USB from PC

• Followed instructions from here: https://wiki.friendlyelec.com/wiki/index.php/NanoPC-T6#Option_3:_Install_OS_via_USB
• Downloaded the tool to flash images
• Powered on using the POWER button while holding the MASK for 3 seconds (Note: attempting start it by plugin the power source was very flaky. After a few attempts I gave up so as not to fry it)
• Note: Below I using their Linux USB flashing tool from here: 05_Tools -> upgrade_tool_v2.17_for_linux.zip but their Windows USB Flashing tools works too for this, just more flaky.
• Uploaded the MiniLoaderAll.bin from the rk3588-usb-friendlywrt-23.05-20231201.zip located 01_Official images -> 03_USB upgrade images using ./upgrade_tool UL MiniLoaderAll.bin from here: https://drive.google.com/file/d/1QNRy1FJocTxDjHdZwoZK2u-1vQR6wf9s/view?usp=drive_link
