IFS QNX image using mkifs builded successfully (ELF type, see attached to get full log)

[image=0x40000000]
[virtual=aarch64le,elf] boot = {
      startup-armv8_fm
      PATH=/proc/boot:/bin:/usr/bin:/sbin:/usr/sbin LD_LIBRARY_PATH=/proc/boot:/lib:/usr/lib:/lib/dll:/lib/dll procnto-
smp-instr-safety
}

mkifs output: 

40000200    100     ----      --- Startup-header
40000300  11208 40000800      --- /tmp/file6FDyfo (1510146467)

I used mkimage to make the image bootable from u-boot

$mkimage -A arm64 -O QNX -T kernel -C none  -a 0x40000000 -e 0x40000000  -n Test QNX arm64 image -d aarch64le.bin uboot-
image.img

The image is recognized successfully by u-boot as ELF image but the boostrap process is blocked after the loading kernel
:

=> fatload nvme 0:1 0x40000000  .boot/uboot-image.img
20608792 bytes read in 10 ms (1.9 GiB/s)
