malloc for c66 dsp

Hi Alice,

.but it has a message "ti.sysbios.heaps.HeapMem: line 307: ti.sysbios.heaps.HeapMem: line 307: out of memory: handle=0x970ee298, size=552968"

This is the SYS/BIOS heap.  You can configure its size via the BIOS configuration (*.cfg) file in your project.  If you open it in XGCONF, you can do it here:

Please refer to section 7.7.2 Specifying the Default System Heap of the SYS/BIOS (TI-RTOS) User's Guide.

Hi Steve

I use the alg_plugins---objectdetection to write my algorithm, and it's not belong to the project...
So I can't enter into the SYS/BIOS heap...

Thanks

hello Steve

I find the memory map... The start of dsp1 is 960a7400

But I edit the size in """""C:\VISION_SDK_02_05_00_00\ti_components\drivers\starterware_01_02_04_05\examples\sbl_multicore_mbx\tda2xx""" 

so... I guess I edited wrong file... 

Hi Alice,

The out of heap error message above is due to the HeapMem heap in your application running out.  You need to increase the size of that heap in your application (as shown in the above screen shot).

Alice said:

I'm not sure I follow you on this.  I don't know what the "alg_plugins---objectdetection" is.

Are you saying that you don't have control over the size setting for the HeapMem heap?

Steve

Hi Steve

Yes, I want say that.
For me, CCS is just a tool to load code into evm board not a code complier.
So I can't use you way to edit the heap size.
I try many way to find where I can edit in vision sdk 0205... but it failed...(like above 6/28 reply)

By Alice

The default heap is specified in the file

\vision_sdk\src\main_app\<soc>\dsp<n>\Dsp<n>.cfg

<soc> = tda2xx or tda3xx or tda2ex - depending on what platform you are using

<n> = 1 or 2 for DSP1, DSP2

Modify line shown in bold to increase default heap size.

Default heap is the heap used by "malloc"

/* create a default heap */
var HeapMem = xdc.useModule('ti.sysbios.heaps.HeapMem');
var heapMemParams = new HeapMem.Params();
heapMemParams.size = 0x80000;

If you still face issues, let me know exact API you use to allocate memory

Kedar

 

Hi Kedar

Today, I changed the size of heapMemParams.size from 0x8000 to 0x100000

it still show the information...

ti.sysbios.heaps.HeapMem: line 307: ti.sysbios.heaps.HeapMem: line 307: out of memory: handle=0x971e6298, size=552968

I would need the below to guide further,

- .map file. Present at vision_sdk\binaries\vision_sdk\bin\tda2xx-evm\vision_sdk_c66xdsp_1_debug.xe66.map

    I assume you are using TDA2xx and DSP1

- The code snippet in which you do the alloc

regards
Kedar

1. width and height may be 96 and 160

2. Above columsum, it can use malloc.... But when I put into """ test""", the program would crash....

3. the map file here

Can you also send me below file
vision_sdk\binaries\obj\vision_sdk\tda2xx-evm\c66xdsp_1\debug\vision_sdk_configuro\package\cfg\MAIN_APP_c6xdsp1_pe66.c

<2>
In this file you should see a array like below
__T1_ti_sysbios_heaps_HeapMem_Instance_State__buf ti_sysbios_heaps_HeapMem_Instance_State_0_buf__A[524288];

Here size of array is the size specified in the cfg file.

<3>
I suspect the heap setting you are doing it not taking effect.

Can you confirm once again the platform and DSP you are using.

Is it tda2xx-evm and DSP1 ?

Is it suitable?

So... I modify the heap size here?

Yes,it is tda2x-evm and dsp1...

Your heap size is 32*KB (0x8000)

__T1_ti_sysbios_heaps_HeapMem_Instance_State__buf ti_sysbios_heaps_HeapMem_Instance_State_0_buf__A[32768];

Can confirm you changed in the .cfg file as shown below ?

Put additional prints in the .cfg file to confirm the change is taking effect, you should see the print during compiling.

vision_sdk\src\main_app\tda2xx\dsp1\Dsp1.cfg

heapMemParams.size = 0x100000; // for 1MB heap size

xdc.print("# !!! Heap size is [" + heapMemParams.size + "] bytes !!!" );

I re-compile...(gmake -s claen >> gmake -s all)

but it has error...

thanks

by Alice

You have syntax error, the it should be

heapMemParams.size = 0x100000;

what you have is

heapMemParams.size = 0x 0x100000;

HI Kedar

I compiled at my end and I see below line in file, can you confirm you see the same,

hi Kedar

The information is same as you...

But it still appears error...

Thanks

By Alice

The heap size is getting reflected now.

Now either you need more heap, so try increasing the heap size further to say 8MB or something

OR

malloc() is getting defined multiple times and its not using the heap whose size we increased.

Try using below instead of malloc. Normally malloc should be using this heap.

#include <xdc/runtime/Memory.h>
#include <xdc/runtime/Error.h>

void *my_alloc(unsigned int size);
void my_free(void *addr, unsigned int size);

void *my_alloc(unsigned int size)
{
    Error_Block ebObj;

    return Memory_alloc(Memory_defaultHeapInstance,
                        size,
                        4,
                        &ebObj);
}

void my_free(void *addr, unsigned int size)
{
    Memory_free(Memory_defaultHeapInstance,
                addr,
                size);
}

Kedar

Dear Kedar 

1.

I try to increase the heap size to 8MB, but it still has error (below the pic)

Weird thing is "the size" gets much bigger than last times (check to above reply) 

2.

I try second solution...

ti.sysbios.heaps.HeapMem: line 307: ti.sysbios.heaps.HeapMem: line 307: out of memory: handle=0x978e8048, size=1281744

Dear Kedar

Could you tell me which file can read the memory space on dsp1?

like...heap(or stack) from which memory allocation and its length...

ex....

DR3_DSP1_DATA : org = 0x84600000, len = 0x00A00000
DDR3_DSP1_STACK :org = 0x85000000, len = 0x00500000
DDR3_DSP1_HEAP : org = 0x85500000, len = 0x00D00000

I need this file to check what happened for my problem I meet now...

Thanks

BY Alice

See .map file present here for the CPU you are interested in

\vision_sdk\binaries\vision_sdk\bin\tda2xx-evm

regards
Kedar

DEAR Kedar

I knew this file...

I wanna ask that ... Is there the "simple" file just introduce stack and heap size...
I can know where heap(or stack) memory starts and its len...

Thanks

BY Alice

No, that's the only way to know this information.

regards
Kedar

DEAR Kedar

How I can know "heap and stack", whether they affect each other...

Thanks
