How to send data to target through Trace32 debugger?

Question

I need a way to send some data to the ucontroller through Trace32. I heard that this is possible some way, but I have no idea where to start.
What I am actually trying to do is run a piece of code on a Aurix TC297 ucontroller to do some measurements (runtime, RAM, etc.). This piece of code is actually a Kalman filter that needs as input a vector of structs that I have too send from the computer through Trace32. Please help !

"A way to send some data to the ucontroller through Trace32" is a little bit vague. There are various possibilities depending on what your actually try to achieve and might also depend on the used CPU family and target OS. Anyhow one of the following might work:

• Simply writing some raw data to the target memory can be achieved with the Data.Set command.
• To transfer a big amount of data (or even a whole application) from a file to the target memory the Data.LOAD commands might be the right choice. E.g. Data.LOAD.Binary command for a raw binary file.
• To set variables in your application or even initiate C-style data arrays use the Var.Set command.
• To write data to NOR flash or onchip flash memory you'll need the FLASH.AUTO command in addition to the previously mentioned commands (after declaring the flash memory to TRACE32).
• To write data to a NAND, SPI or other serial flash memory you probably should use the FLASHFILE.Set command (after initialization of the FLASHFILE programming system).
• To transfer data from TRACE32 to your target while the CPU is running you might have to configure correctly SYStem.MemAccess and use the memory access class prefix "E".
  E.g. Data.Set E:<addr> <data>
  or Var.Set %E <expression>.
• You can use FDX for a bidirectional data transfer between debugger and a running target application.
• To enable the target application to open and read files from the computer running TRACE32, you have to compile your application with suitable semihosting code and initiate semihosting in TRACE32 with TERM.GATE command.
