rebooted it couple of times and still board stuck at uboot.
Any idea what could be the issue?

Tried on other hardware and it worked. Meaning I could flash Image from https://drive.google.com/drive/f ... gAqAeXlaa29rRF82dzA and board boots to android without any issue.
But I could not halt booting at uboot prompt. Looks like uboot delay is made 0.

Can this delay be increased ?
Does the bootloader with this image support fastboot ?
I can flash standard android Image?
could you also provide me refer to uboot code? do we have rk3288 support in mainline uboot?

Thanks,
