FS#3575 - sysupgrade failing on Ubiquiti UniFi AC HD

- Device problem occurs on
Ubiquiti UniFi UAP-AC-HD

- Software versions of OpenWrt/LEDE release, packages, etc.
Builds off a fresh clone of master, and current SNAPSHOT release from

- Steps to reproduce
Following the commit notes from:;a=commit;h=4e46beb31342a2b02e32185e91806093f68a77be

Using firmware compiled from master or using the SNAPSHOT downlaod, will boot and run successfully on UAP-AC-HD.

However, “sysupgrade -n” using the same SNAPSHOT build it is running is resulting in an instant crash and reboot.

After collaboration with Jan Alexander, I used "fwupdate.real -m" to change the u-boot version on UAP-AC-HD to the one included with vendor firmware BZ v4.0.80. sysupgrade is now working perfectly. Thanks Jan!
