maybe a silly question , would it be possible to get a prebuilt uboot image file and burin on emmc to boot rockpi 4b, I hope to get my rockpi working.
Is this the link below to uboot image ?

The link is the pre-built image for the SPI flash.
For eMMC, you can just use the image from https://dl.radxa.com/rockpi4/images/ with -gpt in name.

Just extract the u-boot image inside with dd.

Make sure you use USB C hub if you macbook has USB C ports only.
finally manage to boot installed OS and uboot on emmc. nvme mounts finally sign of relief.
