Hello I am trying to getting started with my new cmucam4, and I have the problem with it ,the message propeller chip lost on com appears.
At the beggining when I first conencted the interface to the cmucam and started the parallax serial terminal the system recognized the version of the cmucam after i tried to update to the version 1.2 this problem of chip lost initiated.
It seems like the firmware is absent in the cmucam. The parallax writes card not detected .
Tried to connect an external supply but the problem persists.
Anyone had such a trouble
thank you

    Hi Andcicc1,

    This is Kwabena - If you haven't solved the problem by now, you might want to just return that CMUcam4 for a refund and get another. Given that it worked once, you also might want to try a different programmer if you haven't already tried.

    Thanks,

    Thank you very much for you answer, it seems like the shop where I bought the cmucam4 doesn't want to refund anything they continue sending me searching on internet the solution of the problem.
    Anyway what programmer would you suggest?

    Mmm, well... I guess you could get a prop plug: http://www.parallax.com/Store/Microcontrollers/PropellerTools/tabid/143/ProductID/398/List/1/Default.aspx?SortField=ProductName,ProductName

    There's probably a distributor in your area you can buy one from. They are essentially the same thing as the FTDI cable.

    BTW, did you set the propeller tool to toggle both the RTS and DTR lines in the options menu?

    ---

    I still have no idea what your problem is, I don't think its the prop chip however as it won't even be found or begin to program if its broken... something must be wrong from the programmer end to your computer.

    Thanks,

    Thank you
    The prop plug that you send me the link slips into 4 pin, FTDI that I have is 6 pin do you think it can be a problem?
    I am using as software the propeller tool, if I try using something else, if exists something else?

    You would use only one of them at a time. The prop plug does not provide power... That's why I don't recommend it.

    Um... for other options... there's BST http://www.fnarfbargle.com/bst.html. But, it doesn't support the RTS pin so you're not going to be able to use SparkFun's stuff with that.

    Then there's the Prop GCC. They have a loader: https://code.google.com/p/propgcc/ - However, its command line. Maybe the SimpleIDE can load SPIN binaries: https://sites.google.com/site/propellergcc/supplements/propgcc-compiler

    Yeah.... The prop tool shouldn't have a problem... I doubt the other tools will get it working.

    Thanks,

    Do you think there is a way to find out if the problem is the programmer FTDI? How can i check that it is functioning?

    Do you have a photo of your current setup with the FDTI cable? That would help a lot.

    What do you mean by current setup?

    A picture of how you have it connected (wired).

    I've tried to use this pogramm and it seems communicating.
    I think when I updated the version of the firmware to v.1.02 something went wrong and there is no any firmware on the cmu. Do you think there is a way to upload the firmware with the help of SimpleIDE? never used Simple IDE

    Oh, it is working? Um... simple IDE uses the prop loader tool. Its a command line thing. You should be able to use it to load the CMUcam4

    Here's the info for the prop loader: https://code.google.com/p/propgcc/wiki/PropGccLoader

    It looks like your going to want to do...

    "propeller-load -e !CMUcam4_Firmware.bin"

    It should automatically find any propeller chip attached and load it. Just find where the propLoader is and launch it. Its probably in the /bin directory where propgcc installed.

    Thanks,

    Thank you very much for your help, I finally succeeded to load the firmaware and it looks the error went away.

    Good for you! Now you can start to use your CMUcam4. Try out the GUI: http://cmucam.org/projects/cmucam4/wiki/CMUcam4_Graphical_User_Interface!
