I updated the uboot from here: uboot-for-qca95xx/bin at master · gl-inet/uboot-for-qca95xx · GitHub
It shows its version as U-Boot 1.1.4-g36de7573 (May 26 2017 - 14:42:18)
I had the same problem as @m.vgunten and needed to mark the unit as tested for it to boot up by default. The commands listed worked. Thanks
I also have the problem that boot_dev does not work with the switch with the case on. As noted by @vigans the switch has three positions and without the case on I can put the switch into the right position to boot NOR.
Am I reading correctly that @mkroes erased all the uboot variables and that fixed the switch to work with boot_dev and the case on?
I am reluctant to try this without confirmation. Wouldn’t I have to re-input all the uboot environment settings for uboot to boot the firmware again?
