I use FOTA to upgrade firmware to version FMA1YX.01.26.01.Rev.99.e and it was OK, devices were upgraded, then we want to upgrade to version FMA1YX.01.27.32.Rev.0.e.CFW.e but its not possible,
Upgrade proces start but terminate with errors, usualy lost conection or flashig failed.
We try few times, on few devices. All time the same problems. Its only possible by usb cable
