Problem with running SYS/BIOS application

Michael Rinker

Other Parts Discussed in Thread: SYSBIOS

Hey,

I want to run a simple SYS/BIOS application, at the moment there is not much to handle.I have only two tasks.

When I debug the application it is terminated and the following messages occurs:

[CortxA8] enter main()
ti.sysbios.heaps.HeapMem: line 294: out of memory: handle=0x800133a0, size=2048
xdc.runtime.Error.raise: terminating execution

A popup from windows says jvm low heap detected.

I`m using windows XP SP3 and CCS 5.1.1.031

Now, is this a problem with the JVM on Windows, CCS or from my sourcecode? How can I fix it?

Thanks for your help

Michael,

The Error message printout means that you've tried to allocate some memory on the CortexA8 but the heap doesn't have enough memory.
To fix this just increase your default Heap size in your *.cfg file.

The JVM low heap is something totally separate. That would probably be a question in the CCS forum if you are concerned about it.

Hey Judah,

my default heap size is 4096Bytes, I have tried the SYS/BIOS sample mutex, which heap size is 8096Bytes, this project runs on the A8.

The heap was to small. Seems logic.

How does I know which size it must have?

Unfortunately you need to make it big enough so that you can run the program. Once you are able to run the program successfully, you can use the ROV tool to see what the peek stack usage is.

To use ROV see: http://rtsc.eclipse.org/docs-tip/RTSC_Object_Viewer
