Hi all,
commenting out FT_GetLatencyTimer() call seems to be a workaround :
#if 0
if ((status = FT_GetLatencyTimer(ftdih, &latency_timer)) != FT_OK)
{
LOG_ERROR("unable to get latency timer: %lu", status);
return ERROR_JTAG_INIT_FAILED;
}
else
#endif
{
latency_timer = 2;
LOG_DEBUG("current latency timer: %i", latency_timer);
}
I have no idea why this function is not working.
This workaround seems to be fixing
Error: couldn't read enough bytes from FT2232 device (0 < 5)
problem that I saw before with libftdi.
However, more surprising are build problems with OpenOCD and D2XX
1.0.4 that I described below.
BR,
Drasko
