I use serial console. Immediately after restart I press ENTER to stop autoboot. Then enter bist and then fastboot. uboot propagates USB command interface.

Looking intpo uboot sources one (only) of the reasons to allow fstor command in bist is to export USB mass storage to charge the device. Once you enter fstor command it sticks there until restart or until battery reaches 5000mV. That's how I charge it now, apart from totally depleting battery first.
