XC-1 not found under Mac OSX

[dbetz]

I've just gotten back to working with my XC-1 board that I bought quite a while ago and I'm having trouble just getting my MacBook Pro to see the XC-1 board. I've plugged it in while pressing the "A" button and I see the three LED flashes so I know it's in programming mode but if I type "xrun -l" no devices are found. Is there a driver I need to install to allow the XC-1 to be used with a Mac?

Thanks,
David

P.S. Mac OSX seems to have noticed that I plugged in my XC-1 board. Here is what it says about it. Is there some reason why xrun -l doesn't list it?

Do you have the ftdi drivers installed don't you ? Which version of the tools are you using ?

Thanks for your reply. I'm using version 11.2 of the tools that I downloaded just the other day. The FTDI drivers may be the problem the problem though. Yes, I have FTDI version 2.2.14 installed. I needed them for my work with the Parallax Propeller. But maybe the driver that the Propeller uses is incompatible with the XMOS tools. I seem to remember that there are two modes and they are mutually exclusive on the Macintosh. Has anyone been able to find a way around that problem or do I need to use a different machine for my XMOS work?

Strange that you mention that they are mutually exclusive... the driver I use for the propeller also works for XMOS... The propeller only needs the UART afaik.

What version of the FTDI driver do you use on your Macintosh?

[dbetz]

If I go to the FTDI site I see two different drivers for the Macintosh, VCP and D2XX. I have the VCP driver installed for the Propeller at the moment. I'm assuming that I need to install the D2XX driver the XMOS board. Is that correct?

[dbetz]

I installed the latest XMOS tools on a Win7 laptop and it seems to be able to see my XC-1 perfectly well. I haven't tried loading any code into it yet but this confirms that the problem is probably with Mac drivers as people have suggested here. I may just use Win7 and leave the Mac to Propeller development for the time being. Thanks for everyone's help!

Hi,

I have installed the D2XX Drivers http://www.ftdichip.com/Drivers/D2XX.htm on my Mac. Interestingly enough I am able to see print output in the debugger. Perhaps that helps you.
I know that in theory the CVP and D2XX drivers cannot coexist, but somehow it works for me.
Never tested if my FTDI-Arduino still works.

Hope it helps

I just found the trick to using the XC-1 from OSX. For the XMOS tools to see it you have to unload the FTDI driver:

Code: Select all

sudo kextunload -b com.FTDI.driver.FTDIUSBSerialDriver

Then you will be able to use xrun and program it. I am using the virtual COM port to receive data from the XC-1 so after programming it I needed to load the FTDI driver again.

Code: Select all

sudo kextload -b com.FTDI.driver.FTDIUSBSerialDriver

I put this in a little script as a wrapper around xrun:

Code: Select all

#! /usr/bin/env sh
sudo kextunload -b com.FTDI.driver.FTDIUSBSerialDriver
xrun $1
sudo kextload -b com.FTDI.driver.FTDIUSBSerialDriver

I am afraid this was on my friend's machine so I am not sure which FTDI driver was installed but I can find out if it makes a difference to anyone.
