So, I’ve manually flash the bootloader to SD card first 4MB unallocated area using dd command. Now the board can run u-boot. However I’m getting the following errors:
** No partition table - mmc 2 **
** No partition table - mmc 2 **
ERROR: Could not find a resin image of any sort.

My partition looks like this:
My resin-boot folder looks like this:

fatload - load binary file from a dos filesystem
Usage:
fatload [<dev[:part]> [ [ [bytes [pos]]]]]
- Load binary file ‘filename’ from ‘dev’ on ‘interface’
to address ‘addr’ from dos filesystem.
‘pos’ gives the file position to start loading from.
If ‘pos’ is omitted, 0 is used. ‘pos’ requires ‘bytes’.
‘bytes’ gives the size to load. If ‘bytes’ is 0 or omitted,
the load stops on end of file.
If either ‘pos’ or ‘bytes’ are not aligned to
ARCH_DMA_MINALIGN then a misaligned buffer warning will
be printed and performance will suffer for the load.
