EK-LM3S8962 on Mac OS

Hi,
I've been trying to make an EK-LM3S8962 board appear on my Mac as a serial port tty.XXXXX with no success.
I've installed the FTDI drivers, but it seems that the problem is that this board has a Product ID set on the FTDI chip that
is not the default. I've tryed adding those to the Info.plist file in the kext but nothing changed ( got this idea from a similar
problem I read in arduino forums ).
Other boards that use FTDI chip work, so i think the driver is OK....

Has anyone got this working??

Thanks.

Thiago

Re: EK-LM3S8962 on Mac OS

I got mine working by adding an entry to the Info.plist file. I could
give you my copy, however, it is for an EK-LM3S6965, so I suspect it
may have different device IDs. You might want to double-check that
you have the right contents added to the Info.plist. Also, I forget
whether I needed to reboot after changing the plist, or do anything
else special. If you want, I can send the chunk I modified along with
where I found the device ids for mine.

You do have another alternative, which is to replace the FTDI device
id/settings on the usb->serial device using FT_PROG:

Here's some relevant forum material, maybe. FT_Prog replaces
functionaly of MProg and VProg:

Re: EK-LM3S8962 on Mac OS

Here are examples of what I added to my Info.plist:

<key>Stellaris Evaluation Board 6965</key>
<dict>
<key>CFBundleIdentifier</key>
<string>com.FTDI.driver.FTDIUSBSerialDriver</string>
<key>IOClass</key>
<string>FTDIUSBSerialDriver</string>
<key>IOProviderClass</key>
<string>IOUSBInterface</string>
<key>bConfigurationValue</key>
<integer>1</integer>
<key>bInterfaceNumber</key>
<integer>1</integer>
<key>idProduct</key>
<integer>48345</integer>
<key>idVendor</key>
<integer>1027</integer>
</dict>
<key>Stellaris Evaluation Board 9B92</key>
<dict>
<key>CFBundleIdentifier</key>
<string>com.FTDI.driver.FTDIUSBSerialDriver</string>
<key>IOClass</key>
<string>FTDIUSBSerialDriver</string>
<key>IOProviderClass</key>
<string>IOUSBInterface</string>
<key>bConfigurationValue</key>
<integer>1</integer>
<key>bInterfaceNumber</key>
<integer>1</integer>
<key>idProduct</key>
<integer>48346</integer>
<key>idVendor</key>
<integer>1027</integer>
</dict>

Note, that I think you can't just use the hex values for idProduct and
idVendor, you'll need to convert them to base 10.

In case when you edited the file you changed the permissions and OS X
isn't happy, you can also try repairing permissions.
