NDK helloWorld example Server Daemon does not recognise breakpoints

Bernard Oliver

Hi,

The 6678EVM NDK helloWorld example uses DaemonNew() to launch a task thread as a Server Daemon,  and it works as expected. i.e. it responds to Ping.  

However, CCSv5 does not stop at the hardware or software breakpoints I insert in the server code, nor will it print messages embedded in the server (using printf() or platform_write()) to the console.

I suspect this is something I don't understand rather than a fault. Can someone please explain?

Regards,

Bernard

    Hello Bernard,

    I'm not sure what is going on either. Could provide more details so I can try this out? What is the full version number of your CCSv5 installation? What emulator are you using? What version of the NDK are you using?

    Thanks

    Ki,

    I am running the TMDXEVM6678LE evaluation board with the XDS560V2 mezzanine emulator using CCSv5.1.0.07001 and ndk_2_20_04_26.

    The problem occurs with the mcsdk NDK example helloWorld which launches dtask_udp_hello() in file udpHello.c as its server daemon. 

    dtask_udp_hello() runs OK as it responds to the Ping commands from the host. However, while I can set breakpoints in dtask_udp_hello(), CCS will not stop on them. Also any printf() or platform_write() commands that I include in dtask_udp_hello() are ignored.

     

    Regards,

    Bernard

    Ki,

    Problem is sorted. It turns out that the response to the host's Ping does not come from the server daemon (dtask_udp_hello()). When I use the winapps example program provided with ndk, the daemon is called, the breakpoints work and messages print as expected.
