Hello all, I started using an FTDI FT245R over Summer to control an FPGA. I found both the D2XX and VCP drivers to be unreliable so recently switched to using libftdi. However, an error that I was getting with the D2XX drivers I've started getting again with libftdi, has anyone seen this before? In '__CFRunLoopLock', file /SourceCache/CF/CF-550.29/RunLoop.subproj/CFRunLoop.c, line 438, during lock, spin lock 0xb0395eac has value 0x80000001, which is neither locked nor unlocked. The memory has been smashed. I've not been able to completely trace this to libftdi, but googling the error leads to other people using FTDI chips and receiving the same error. Also, I never saw this error using the VCP drivers with the same application. Does anyone have an ideas? I'm developing on Mac OS X 10.6.4 using Qt 4.6.3. Regards Dan libftdi - see http://www.intra2net.com/en/developer/libftdi for details. |
