AM3358: sysbios heap size increases binary size

Part Number: AM3358
Other Parts Discussed in Thread: SYSBIOS

I have ti-rtos (SYSBIOS) app running on a Pocket BeagleBone. In this app, I am allocating a large buffer maybe 2 MB to store some data. To get malloc to work I've increased the heap size in the .cfg file. This also makes the app binary image much larger.

In the app, I am initializing the buffer to 0's, then writing data into it as the app runs. Is there a way to be able allocate the big array without making the app image larger also?

The system is using the sd-card to store the MLO bootloader and the app itself. The larger app is also causing system to boot slower than if the image were smaller.

    Hello,

    Please refer to this thread which discussed about a same issue and had a solution at the end.

    Please also note that TI has stopped supporting TI-RTOS based SW development for AM335x, as announced here. I would recommend you to check the consolidated resources provided in the announcement.

    Regards,
