This is about 22KB/s. What if you use libftdi 0.16? It is supposed to be faster with the async mode under Linux. > The new fast speed approximately equals the performance of amontec > JTAGKey on Windows with the amontec-supplied libftd2xx and r717-ish > openocd. That is quite nice. Maybe with libftdi 0.16 under Linux, it can beat the Windows libftd2xx version. But on the other hand, maybe you can try the latest version with libftd2xx under Windows. The data would be interesting. Supposedly that would still be faster. > I don't have the actual numbers to hand but can post them when I get > back if this is interesting. Please post it.
