CCS5 Debugging multiple targets

Janos

Hi guys,

i have several custom boards connected to the computer, all of the same type holding a TM4C1231H6PMI TIVA processor. Durnig firmware development using CCS5, i need to program several of them all the time. The debugging interface is the FTDI solution from some older Stellaris development board, so i have the boards plugged in via USB and can program and debug them over the ICDI drivers provided by TI.

This works nicely for a single board. But how can i tell the CCS5 to program and debug a specific target, when several FTDI bridges are plugged in? The same question has to be asked, if i would want to use more than one LaunchPad at the same time. So this is rather a general question and not specific to my particular setup.

When i do have more than one target connected, and press the "Debug" button in the CCS, then any ONE of the targets is being programmed. I don't know how CCS choses which one, and i don't know if it is always the same one. But in order to program all the targets, i would have to unplug them all and have every single one plugged in seperatedly. Afterwards they'd all needed to be plugged in in order to work together.

Can i give the CCS any hint how to chose the target which i want to be programmed? Is it maybe also possible to use the LM Flash Programmer to program multiple devices at once?

My environment is Windows 7 32bit, the CCS version is 5.5.0.00077. The FTDIs are programmed with Vendor-ID=0x0403, Product-ID=0xBCDS, and individual serial numbers.

I'd be glad about some hints!

Thanks a lot,

Janos

Hi Janos,

Here is a similar post from Stellaris forum.

Hi kel,

thanks for your directions, but that doesn't answer anything regarding neither multiple connected targets nor the Code Composer Studio.

Cheers, Janos

Hi Janos,

I saw this post below before at Code Composer Studio. But this is for debugging two targets Concerto and Piccolo. I am not an expert with this configuration to comment further. Much better to also post your question at CCS forum.

Hi kel,

thanks again, this has led me into the right directions.

It seems that debugging multiple targets using the ICDI of the Stellaris/Tiva devboards is *not* possible. The CCS cannot be configured to make a difference between targets. That is however possible with the XDS100 emulator (which i don't have).

Learned here: Multiple target debugging: CCS5 and Stellaris ICDI (Eval Boards)

Remains the question, if it is possible via the LM4 Flash Programmer command line? Where is that tool documented anyhow? I can't seem to find any TI references about it.

Cheers Janos

I have never use the LM Flash Progammer Command Line. You can find some info about that at the "Help" of LM Flash Progammer.

I think the document related to LM Flash Programmer is the Stellaris Serial Flash Loader Application note. Search that at the TI website.

Ok according to the command line help, there is no possibility to specify a specific ICDI/JTAG target for programming.

Thanks for your help!
