I was able to boot the image you sent, thanks!
It works but I was not able to get wireless to work, it doesn't seem the module was loaded, full log at the end:

This seems to be related to the Zigbee module, so no big deal:
[ 1.172720] spi_master spi1: spi_device register error /soc/spi@78b6000/em358x@0
[ 1.178424] spi_master spi1: Failed to create SPI device for /soc/spi@78b6000/em358x@0
It also doesn't seem to have the mmc module so I wasn't able to try to map anything. Maybe I'm missing something.
