FreeRTOS+Trace code error

Other Parts Discussed in Thread: HALCOGEN, TMS570LS0432

I use Hercules Launchpad TMS570LS0432 kit and FreeRTOS v8.1.2, and I use Halcogen for code generation. I tried inserting code for Trace Options available with Tracealyzer from Percepio(FreeRTOS+Trace). After adding the necessary header and source file provided by percepio into the project, code build results in error

error #10099-D: program will not fit into available memory. run placement with alignment fails for section ".kernelHEAP" size 0x2800 . Available memory ranges:
RAM size: 0x6300 unused: 0x1a50 max hole: 0x1a50

The software uses on chip RAM for recording the Trace. Kindly suggest a solution to get rid of this error

Sindhu,

Apparently you are running out of the available RAM space. May be if you could post the linker as well as the .map file, we can have a quick look at it.

Hi Karthik

I attach the .map and linker file4341.IdleCountMap.txt

Hello Sindhu,

If the tool you are using is storing the trace information in RAM, then the TMS570LS0432 is not the best option for you to use if Trace is required. This part number only has 32KB of RAM. You might consider moving to a device with a larger memory if possible or. as Karthik has suggested, reduce the size of the heap in the linker command file. Note that reducing the heap size will reduce the size/depth of the trace buffer.

Thanks Chuck and Karthik !

Reducing the heap size from 8kB to 4kB let the code build. That was of great help to me !
