The file was too big (50MB). `bootflow scan -lae mmc1`
In boot/bootmeth_efi.c, bootmeth_alloc_file is set to a pre-defined 32MB so bootefi cannot boot anything larger than that even if you have CONFIG_SYS_MALLOC_LEN set to something larger.
Hope this helps someone.
Thank you for this. I sent a series[1] to drop the memory allocation, which should resolve this. If you have time to test it, please do!
