LA9310 unable to connect to CWIDE

varun0106 — Tue, 08 Mar 2022 13:49:27 GMT

I am working on LA9310RDB, when i try to connect VSPA using cwide, it throws following error

"CCSProtocolPlugin::Can't connect to CCS"

I have configured the IP of jtag.

I also saw a link on the internet for the same, "https://community.nxp.com/t5/CodeWarrior-Development-Tools/Can-t-connect-CCS/m-p/459955"

But I am not able to understand anything from this, as it is a 6 year old post and CCS window is not there in CWIDE now

Hi, Varun,

This is an update to your question/request:

go to the ccs command line window and run the following command before you run the debug in CW

As you can see below VSPA is not in the jtag chain by default.

Once you do the write_mem commands below the VSPA is added to the jtag chain.

Good luck

Hi,

It appears that you can not open the ccs menu, this is the screenshot which tells you how to open the ccs menu. I use the CodeWarrior for DSP56800E tools, but the menu is the same.

Hope it can help you

Hi Xiangjun,

I started the CCS server manually from the cwide setup folder, then i started executing the commands which you have mentioned earlier, i got error in the third command "ccs::config_chain {la9310 dap}",

the error states "can't read "::ccs::core(la9310)": no such element in array,", what does it mean?
