Problems talking to CC3200 Launchpad with Energia

Former Member

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.

  • I have first installed CCStudio. Well, it took several hours. It installed also the necessary hardware drivers.

    Afterwards when I run  Energia, no additional drivers were needed.

     

    Second idea is that may be you could try running Energia on another PC.

    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 :-)

    Thanks, yes I put a request on the Energia forum, I'll see what transpires.

    You comment about Leonardo's is noted - I hope I don't have driver issues but I'll find out soon enough!

     

    When I do get my project working - with whatever hardware - I'll put a more positive blog up. My project is a beehive monitor, all sensors working on an Arduino Uno, just need the web link!

     

    cheers

     

    Adendum

    ========

    Have now had it confirmed (Energia forum)  that the V2 bootloader is not supported by Energia. So I'll be getting another unit, hopefully it will be to current release levels.

    @BigG: Hi, I had a similar problem than Geo Meadows, and followed all the suggestions that had been proposed but no success.

    The error that Energia gives when uploading the sketch is the following:

     

    Opening \\.\COM26

    Getting storage list

    Bootloader Version: 4

    Silicon version ES1.32

    Bootloader version is 2, 1, 4, 0

    It's a CC3101 device: PG1.32

    BlockSize is 4096, number of blocks is 64

    erasing 1 blocks starting from  4

    Switch to NWP bootloader complete

    Silicon version ES1.32

    Bootloader version is 2, 0, 4, 0

    BlockSize is 4096, number of blocks is 16

    erasing 12 blocks starting from  0

     

    Also, I installed CCS and all the required drivers and SDK to run some code in the CC3200 module, and I didn't have any problem using CCS.

     

    Any suggestion to fix the problem I am facing?

     

    Thanks a lot in advance.

    You are missing some vital lines of information. What happens after "erasing 12 blocks starting...."

  • in reply to BigG

    @BigG : After "erasing 12 blocks starting from 0" the uploading process stops and Energia gives the message "Uploading failed".

    Anyway, I followed the suggestion from this page https://github.com/energia/Energia/issues/507 and now I have no problem uploading sketches. The main problem was the version of the Launchpad I got, which is version 4.1.

  • in reply to Former Member

    Excellent stuff. Glad you got sorted. I see from link you provided on this issue that there is a new Energia patch to handle your launchpad's new bootloader version 4: http://energia.nu/files/cc3200prog_win.zip
