Problems talking to CC3200 Launchpad with Energia

30 Oct 2014

I've spent several hours trying to communicate with the above controller using Energia but without success. I'm really hoping someone will take pity on me and offer some ideas!

The problem I think is with the drivers, or lack of them. I downloaded the driver zip as recommended by Github (EZ430-UART.zip) and unzipped them. If I plug the CC3200 into the USB port Windows tries to install the drivers but when I direct the driver installation wizard to the unzipped files it seems to think they are not relevant and so fails. If I open Device Manager then the CC3200 is showing up as USB<->JTAG/SWD but with a query over it as there are no installed drivers. I wonder if that is telling me something, I would have thought I really needed a COM link not a JTAG link (?). I've tried this on a 32 bit machine and a 64 bit machine - same results.

I have a project waiting to go online using WiFi and this is really frustrating. I get the feeling it's something quite simple but I can't seem to see it. I've checked all the PCB links against the TI User Guide and can't see any problem.

Yes you have got further but it is crashing because of an old bootloader installed on your cc3200.

I think I am correct in saying that issues relating to bootloaders are linked to the firmware on the device. You have to upgrade this part manually before use.

Have to follow the instructions to upload new firmware onto the cc3200 (you need the service pack: SimpleLink Wi-Fi CC3200 Software Development Kit (SDK) - CC3200SDK - TI Software Folder)
Instructions on what to do are given here: cc3200 hardware guide | Energia
As said you will need to use Uniflash to upload the servicepack / new firmware onto cc3200. Then you should be good to go with Energia.

OK, thanks
Tried that and Energia gets a bit further but hits another problem which I don't really understand. Hmmmm.

Looking at picture above I wondered whether you have done the following:
- Remove both jumper J8 and SOP2 if they are installed
- With the USB connector facing up, connect one side of the jumper wire to the top of J8 and the other side to the bottom of SOP2

I take it you have read the information provided in Guide_CC3200LaunchPad | Energia
and http://energia.nu/cc3200guide/

within the cc3200 guide there is another link to the windows setup process Guide_Windows | Energia

On this page look at listed item 2 where there is a link which when clicked will download a zip file with the required drivers.... I don't know much about the Github option (that may be for the 430 controller anyway, so may not be relevant)

Need to do that before connecting anything.

... I now see your uploaded images. Maybe refer to the FTDI section for an explanation on the "ACK failed" message.... just added link to make it easier FTDI Knowledgebase
... and I take it you have the jumper placed in correct position to allow for programs to be uploaded via Energia: http://energia.nu/wordpress/wp-content/uploads/2014/09/jumper.png

To upload any updated firmware onto the cc3200, all you need is the Uniflash program, which is a utility that will upload files onto the cc3200 for you.

You do not need to CCStudio for any of this.... otherwise you spend a couple of hours downloading and configuring that which can be done later as Energia should suffice to get you going.

Hope that helps.

Thanks for that. Taking the second idea first, I tried that, same results.

I eventually downloaded and installed CCStudio, TI certainly don't make it easy with all the security loops you have to jump through and the many installation issues that pop up. Then I re-installed drivers for the C3200LP using Device Manager and pointing it to the Drivers folder that got installed with CCS. All good. When I plug into thew USB port it shows up as follows, so the drivers seem fine. I'm using XP by the way.

Next hurdle is Energia, which sees the CS3200, as com14, but won't download the Blink program, it complains as shown below.

So I wonder if I have a link setting issue, below is the LP link set, maybe someone can see something wrong here?

I'm tantalisingly close!
So much effort to get an LED to blink :-)
