Too few RTDX Host Buffers

My configuration is CCS v4.2.4, DSP/BIOS v5.41.10.36, NDK 2.20.00.19.

I am using ZOOM development Kit OMAP-L138. this maybe EVM board.

When I have been using for several minutes, I meet above warning message.

In order to resolve this problem, I had wandered TI site so many times, so found this article.

Six-core devices ("Too Few RTDX Host Buffers") paragraph

but this is for BIOS v6, this is the closed post for my problem.

I opened scriting console, typed 

//=================================================================

js:> <source lang="text">loadJSFile c:\initRtdx.js</source>
ReferenceError: "XML" is not defined.

//=================================================================

I got the above result.

I don't understand. How can I do?
