CCS/TMS570LC4357: Code Composer Debug issue when offline from Internet

user4607145

Part Number: TMS570LC4357
Other Parts Discussed in Thread: HALCOGEN

Tool/software: Code Composer Studio

Hello,

Hopefully this is not a topic that was discussed before, I failed to find a similar issue. So I am using the TMS570LC4357 with Code Composer 7.2.0.00013.

My problem is that I am generally using a VPN connection when working with the MCU. I was using it when installing Code Composer, HALCoGen, etc. If I go offline from the Internet or I use a different public network to connect to, Code Composer does not allow me to debug my programs. As soon as I can reconnect to my VPN connection, I can debug my programs with no additional problems. Flashing works fine, and programs work on the board, just CCS does not allow debugging.

Why is this restrictive? Is there some kind of license problem with Code Composer? This issue is a significant for me since there may be a lot of times that I work completely offline from Internet.

Thanks,

Tudor

    The only restrictions that first come to mind when working off-line would be with Updates and Resource Explorer. There should be no impact to debug at all. CCSv7 no longer checks for a license so there is no issue with licensing also.

    Please describe in more detail what exactly happens when you try to debug while off-line

    Thanks

    Hello ki,

    If I use my VPN connection when I click the debug button, it flashes normally and program stops in the main function, and I have to use the green play button to start my program. So, let's say, i can go step-by-step with my program. However, when I am either offline, or using different network, when my program flashes it no longer stops at the main function, it just runs. Everything related to step-by-step execution or pausing is greyed out. I can only click the red square that stops the execution of the program completely.

    I am using one of the simple CAN Examples in HALCoGen and used two different TMS570LC43 boards. I have not yet tried to use a different PC.

    My assumption is that perhaps during installation of CCS it remembers somewhere the network and maybe there is a constraint there. But otherwise, I have no idea why this happens.

    Thanks
    Tudor

    Can you provide a screenshot of your whole CCS environment when those options are greyed out?

    Thanks

    Hello ki,

    See below the screenshot. It's just a simple CAN protocol example. I've checked with an oscilloscope, and for sure it flashed correctly and program is working on the board. Just once I hit debug, it flashes and reaches this state. I've also uploaded a picture of CCS when I am connected to my VPN and debugging works properly. The only thing I am doing different is my Internet connection

    In your second screenshot, a proper debug context is not selected. Note how the top node (Project being debugged)is selected in the Debug view while in your first screenshot, a proper debug context is selected (sub-node underneath). In your second screenshot case, select the node underneath the name of the project being debugged.

    Thanks

    I did what you suggested. Now I am able to use reset and pause the program. However, any breakpoint is ignored in my main program. I can set the breakpoints, they are blue, and the program does not stop at them. I tried to reproduce the problem on a different PC, and I could not manage to do it. I will try complete reinstallation of Code Composer.

    You may have enabled the "Skip all breakpoints" option in CCS

    If it is enabled, try disabling it.

    If that is not an issue, please provide a screenshot of your breakpoint sin the source code and in the Breakpoints view

    Thanks

    Additionally I can tell you that my access to the Internet is restricted when Firewall is on. If I have my firewall, the debug process is blocked, and continues only when i disable my firewall. However, the breakpoints issue is still there no matter what

    You do not need internet access to debug. You can have no internet access at all and yet be able to run the debugger. There is some other issue going on. Maybe a CCS process is getting blocked by your security software. Do you have any more information like an error message?

    I see one active HW breakpoint at line 93 and a bunch of disabled HW and SW breakpoints elsewhere. When happens when you try to enable them? Do you get an error message?
