Notoriously I face programming problems with S12XE devices (mostly XEG128 and XET256, sometimes with XEP100).
Frequently I get HiWave error messages (see attachments) every time I want to reprogram flash with PE Micro USB Multilink Interface.
I have to Unsecure my device every time I face this problem (so quite frequently). Then loading application (abs file) works OK for a single time.
HiWave version 6.1 Build 10221
