Trouble installing the Mr Chromebox firmware-util script

[joshtbw]

When I try to run the Mr Chromebox firmware util script I get the following error:

firmware-util.sh: warning: firmware-util.sh: warning: script from noexec mount; see https://chromium.googlesource.com/chromiumos/docs/+/master/security/noexec_shell_scripts.md firmware-util.sh: line 38: warning: ./sources.sh: warning: script from noexec mount; see https://chromium.googlesource.com/chromiumos/docs/+/master/security/noexec_shell_scripts.md firmware-util.sh: line 39: warning: ./firmware.sh: warning: script from noexec mount; see https://chromium.googlesource.com/chromiumos/docs/+/master/security/noexec_shell_scripts.md firmware-util.sh: line 40: warning: ./functions.sh: warning: script from noexec mount; see https://chromium.googlesource.com/chromiumos/docs/+/master/security/noexec_shell_scripts.md mount: /tmp/boot: wrong fs type, bad option, bad superblock on /dev/mmcblk0p12, missing codepage or helper program, or other error. Error mounting boot partition; cannot proceed.

Unable to download cbfstool utility; cannot continue

Can anyone help me work out what's going wrong here? I've followed the steps as outlined in the readme and I have gotten the correct responses as per the readme.

I've even tried to remount the partition as exec but this doesn't seem to work either.

I got the same error, and was able to make it work with these:

sudo mount /tmp -o remount,exec
sudo mount /home/chronos/user -o remount,exec

The second command returns mount: /home/chronos/user: mount point not mounted or bad option
