Yes. One possibility is to use "fastboot oem exec <cmd>". This can be a
bit tricky since the fastboot string length is very limited (64 bytes I
think). The other possibility is to create a multi gadget which also
creates a console. See the global.usbgadget.acm option. With this you
can remote control barebox via a USB serial console. You might want to
look into the labgrid project which integrates all this nicely.
