USB driver for OS X 10.7 -- not getting any '/dev/ttyXXX' showing up

Hi

I'm brand new to the Maple. I'm using an iMac -- OS X 10.7 (Lion).

I've just received my very first Maple Mini and followed the command line tool chain instructions. Every went well right up to the point I am supposed to see a /dev/ttyXXX. This doesn't happen. I tried it in "perpetual bootloader" mode as well (still not sure exactly what that means ... but I get the slower blinking LED to confirm it's engaged, right?) No difference.

I have two other USB serial interfaces, which both work. One comes up as /dev/tty.usbserial, the other as /dev/tty.usbserial-FTCDIWIU. I've used 'screen' with them both successfully, many times.

The Maple doesn't seem to be recognised at all in the Apple "System Information" (The old profiler) app -- unless I initiate perpetual bootloader mode, in which case it shows up as "Maple 003".

Regardless, I get no 'tty.usbserial' or equivalent, whether in bootloader mode or running the sample program from examples/test-session.cpp

Thanks in advance for any help.

P.S: Could it have something to do with 64-bit drivers not being present for whatever 'chipset' the Maple is emulating when running the test-session program? But if so, it should still show up in System Info. Hmmm.

Ah! I tried the simple LED blink test program as well. That didn't work.

Finally, I installed the IDE and noticed there are three versions of the Maple Mini. Selecting REV2 has made everything work. Yay \o/

Now I just have to figure out how to make the tool chain make / dfu-util understand this.

OK. Reading the Makefile provided the answer.

Change ...
BOARD ?= maple
... to ...
BOARD ?= maple_mini

(make clean)

Can I suggest a small addition to the command line tool chain docs to talk about telling Makefile the correct board?

Now to have some fun! :D

Cheers.

I got hung up on getting my Maple Mini to work with libmaple as well. But I did change the BOARD variable. I just didn't do the "make clean" afterwards. So that is probably needed when changing boards as well.

Good point.

And yes, our Makefile isn't smart enough to know if you've changed boards since the last compile, so you'll need to make clean if you switch the board. A patch to fix this would be nice ;).
