At the moment pressing the volume down key does not actually launch fastboot. This is because setting "bootdelay" to "-1" actually disables autoboot and drops to the U-Boot console. It does not execute the "bootcmd".
The correct value for "bootdelay" here would be "-2", which disables the delay and key checking and would immediately execute the "bootcmd".
However, even better in this case is using "preboot" to trigger Fastboot. The advantage is that running "fastboot continue" will actually continue the autoboot process instead of ending up in the U-Boot shell.
Also make sure to unset "preboot" again immediately in case the user saves the environment after triggering fastboot.
