FT2232 drivers on MacOSX

From DP

Jump to: navigation , search

An irritating thing about MacOSX is that you have to unload FTDIUSBSerialDriver.kext serial driver to use the MPSSE (JTAG) features.

There is a workaround for that, but it is a trick and should be used by individuals only, surely not in the production device.

You can change the VID/PID of FT2232 to something non-existing and specify the new VID/PID when connecting with urJTAG or OpenOCD.

cable ft2232 pid=0xbb02

I have changed my PID to 0xBB02 and it works perfectly along with FTDI serial drivers. All I have to do is use PID parameter when connecting.

Thanks pppd!

urJTAG

cable ft2232 pid=0xbb02
