Reading some old e-mails in the thread "Re: [UrJTAG-dev] [RFC] Optimize TMS clocks for FT2232" i see this explanation: > > Another more interesting example is it will optimize > > 0x4b 0x00 0x7f 0x4b 0x00 0x7f 0x4b 0x00 0x00 0x4b 0x01 0x7f > 0x4b 0x00 0x00 0x4b 0x00 0x00 > > into > > 0x4b 0x06 0x1b I believe that the "RUNTEST IDLE 52000000E-6 SEC;" svf instruction is constructed with a bunch of TMS clocks commands for the FT2232H cable, and maybe the compaction of these commands do not take into account the maximum size allowed, or something like that. I will analyze the code to try to detect a bug like that. Maybe Jie Zhang and/or Arnim can help us to identify the problem.
