Hi! All

I am using Code Composer 7.2

What I would like to achieve is the following:

I create an array at compile time, it's address might change every time I modify the system, lets call this variable arraydata.

During system runtime I fill up the array with debug data, the size of this is stored in a variable, which we shall call datalen

Now I would like to create a Scripting Console command which can read out the data from this array to a file.

I do know I can use the command saveRaw

Syntax: saveRaw(page,address,filename,length,typeSize,byteSwap)
Arguments: 
  page - the memory page, use one of PAGE_X constant.
  address - the first address in the block.
  filename - specifies the name of the file that store the target data.
  length - the number of bytes to save.
  typeSize - specifies the type size of the data.
  byteSwap - force a byte swap of the data before writing to target memory.

For this I need 2 things:

Get the address of the arraydata
Get the size of data written into that array, which is stored in datalen

How would I do this automatically with one or more commands in the Scripting Console?

Hi,

I am not entirely sure what target are you using, but one way to do this is to use Debug Server direct access. In the example below I have a single core device, a running debug session, a program already loaded to the target and I am saving 32 bytes of 32 bits of a variable named "results1" to a directory on the C: drive.

scriptingConsole said:

debugSession = ds.openSession(".*");
saveRaw(PAGE_PROGRAM,debugSession.symbol.getAddress("results1"),"C:\\temp\\results_output.txt",0x20,32,false);

Keep in mind that, for multi-core devices such as AM335x or AM572x, you will need to pass the correct core. To list all cores available and to select the correct one do the following:

scriptingConsole said:

js:> debugSession = ds.openSession(".*");
Could not open session. Found 9 devices matching: .*
