So I have a fully operational linux system with barebox as bootloader. In production environment I have no access to the serial console but I have a USB OTG port. For security reasons I don't want USB active in my "normal" barebox environment, so it's off by config. For support, to gain access to a barebox and bootloader functionality is there a way to load another barebox (with usb active) from linux userspace into RAM and start/reboot into that? Have a nice weekend! Regards, Patrick _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
