Then under the sandbox I do the following:

As you can repeat this under sandbox, the next step would be to run sandbox under gdb, e.g.: $> gdb --args sandbox -c "host bind 0 /tftproot/rootfs.raw ; host load hostfs
- 0 /tftproot/opos6ul-linux.bin ; ext4write host 0:2 0 /boot/opos6ul-linux.bin
${filesize}"
Yes, I did this and it crashes exactly where I pointed out in my first post:
