TMS320F28377D: Using DSS with multiple XDS220 debug probes in parallel

Hi Ki, 

I am using DSS inside CCS 8.3.1 to run two XDS220 ISO Emulators in parallel.  If all emulators have stable connection, the flash program continue to work well. Once I power cycle all the XDS220, for the first couple of times, program will not be able to establish the connection to one of XDS220 emulators.

This issue happens quite often. Actually, we saw this issue on DSS uniflash3.4. Do you have any solution to this?

Thanks,

Chao

    Hello,

    I split this post off to a new thread since it is unrelated to your original post.

    I assume the reason is that the debug probes must reboot and reconnect to the network, which will take a bit of time. Assuming this is the case and is expected behavior, there is not much you can do but delay the script execution until enough time has been given for the debug probes to be fully initialized. Some users have simply added a delay in the script to account for times when the debug probes are power cycled. This is likely the easiest (if somewhat crude) solution. I suppose other options are something like pinging the IP address of the debug probe and wait until acknowledgement is received. 

    Thanks
