Was the flash.bin aligned differently before the binman conversion , or 
did it work with UUU by sheer chance ? I don't see any alignment changes 
during the binman conversion.

tools/imx8mimage.c does contain

  33 #define ALIGN_SIZE              0x1000

But that should be called internally by binman anyway.

Is the flash.bin correct or is it already corrupted when generated by 
this binman stuff ? You should be able to extract the u-boot.itb from 
flash.bin and run mkimage -l on it to validate it.
