bug in resync (MPSSE)

Bug was found in SCK-pulse synchronisation in following conditions:

  • firmware sets high level on SCK pin;
  • an MPSSE-based adapter is used (FT2232, FT4232, FT232H).

Microcontroller can be programmed again via USB-based adapter after erasing via LPT-based adapter.

In my case the bug appears with AT90S8515 but not reproduced for ATmega168.

Bugfix will be published as soon as possible.

The bug has been fixed in version 1.28r13.
