RTOS: TDA2 RTOS bmp array heapmem

Tool/software: TI-RTOS

Hello,

We want to create a array for bmp of RGB888, and convert it to RGB565.

When creating a array [1024 * 720 *3] and compile, we will get some error.

We guess they are because of HeapMem, or overflowed ...etc

But we can successfully compile when we create a array [640 * 480 * 3]

Q1：Can we create a array [1024*720*3], and we can successfully compile ?

Q2：where could we get information of heapmem setting from code or document ?

Thank,

Ting

Hi Ting,

How are you allocating the array. Are you specifying some section or allocating from stack?

What is the build configuration you are using?

Hi Rishabh

Thanks for your reply.

I create a array and give it value, like

"static const unsigned char bmp_test[] = {

117,104,85,69,56,37,30,19,2,73,......}"

Counts of value are size of array, and now it is 1024*720*3.

I have find some memory setting for A15, IPU......

But I don't know how to match my array

Thank,

Ting

Hi Ting,

It seems that you are allocating buffer from stack, you need to allocate from UTILS_HEAPID_DDR_CACHED_SR.

You can grep the same in Vision SDK to see how to use it.

Hi,

I haven't heard back from you, I'm assuming you were able to resolve your issue.
If not, just post a reply below (or create a new thread if the thread has locked due to time-out).

Hi Rishabh

Thanks for your reply.

Sorry, I have another thing to do, but I will grep "UTILS_HEAPID_DDR_CACHED_SR".

Before I try that, maybe I can end this problem.

When I get a new problem, I will ask a new question.

Thanks,

Ting
