Many thanks for making these tests! Awesome! Xiaofan Chen wrote: > Actually the result is pretty close for the LPC-P2148 based test. > jtag_khz = 1500 KHz, 38.927 KiB/s (ftd2xx) versus 38.754 KiB/s.
So in conclusion there is almost no difference in performance between OpenOCD using libftdi-0.19 and ftd2xx, or did I overlook something? If not, I would suggest to only use libftdi in OpenOCD. Uwe, do you see a possibility to port libftdi-0 over to use the libusb-1 API? If only synchronous is used it should be straight forward. I'm not saying that *you* must do it, but am rather asking how much effort it might be. The benefit for OpenOCD would be that it can use libusb-1 on Windows without first having to rewrite the ft2232 driver. That rewrite is absolutely desirable, but it seems that everyone agrees that the driver deserves and needs a thorough job, so would be nice to be able to punt on that and still be able to start using WinUSB and libusb-1. //Peter _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
