Might I suggest the first post on this thread be edited to correct the links...

Or log in to your router with your browser and check the DHCP table there.   In Linksys routers, this is under the Status tab.  (I'm not at home, so don't remember the exact path to this display.)

Has anyone gotten this installer to work on Mac?   Or just openocd?   

Any suggestions for a simple command to test openocd with my plug before I try to make it update the code?

I've yet to look at the installer code, but I did get as far as reinstalling MacPorts (which got screwed up in the course of moving to a new machine and then upgrading to Snow Leopard.)  I then was able to  port install openocd  to install a Mac native OpenOCD 2.0.   Next step is to dig around to find how to make its config file, etc.

Looking around MacPorts, it seems there may be most of the tools needed for development on OS X, so yes, there is interest.   I hope this is mostly a matter of making scripts portable.

I updated to OS X 10.6 Snow Leopard last weekend and got a chance to get back to the Sheeva Plug this weekend.  The serial device driver installation which was done under Leopard came through just fine.  Now to press on to getting OpenOCD installed and trying it.  It appears to be available through Macports. 

Seems to me that one way to do this would be to redo the development piggy back board such that the SD socket is moved back enough that the card is within the case.   For production, insert $MEMORY_CARD_OF_CHOICE and put on a lid which covers the card and usb console port.  The development system lid would have a recess to allow access to the SD card.

I switched to another USB cable which fit securely and then it worked fine. 

I ordered mine on July 16.   Around August 10th(?) I noticed that Global had immediately billed my credit card when the order was placed.  Concerned that I the information I had from the order tracking page did not clearly reflect this billing and that I might get double billed, I called Global to inquire.  I was assured that I would not get double billed and that a shipment of Sheeva Plugs was due in on Aug 14th.  Mine would ship by the 17th.   In reality, they did better, shipping my plug on the 14th via Fedex Ground, as I'd specified.   It arrived on Aug 19th.   

Interestingly, the warranty period is 30 days from date of purchase.   Global "will, at it's option, either repair or replace the product without charge, provided the product is returned during the warranty period."  (my emphasis)   So, technically, the warranty expired before I even got the product.      I think they need to adjust this policy...

Interesting.   Does everyone get a different set of serial devices?   After going through the driver install procedure, I wound up with /dev/cu.usbserial-00002006A & B.  Took me a while to figure out that I'd been lucky enough to be shipped a defective USB JTAG/console cable.  The one I was shipped did not fit snugly into the Sheeva's socket.  Fortunately,  I had several spares from old digital cameras.

For those unfamiliar with screen (as I was/am), here's a link to the GNU Screen documentation.  The most important thing (which I know I've seen elsewhere,) is that to exit, type control-a control-\ .   Looks like it should be possible to set up a .screenrc file in my home directory to automatically supply the device and speed parameters.

I'm looking forward to some serious fun with this device.
