Linux/TDA2: On-Chip Shared Memory (RAM) 512KB

Hi Anuj
UTILS_HEAPID_OCMC_SR and UTILS_HEAPID_L2_LOCAL which is fastter?
omapconf show opp not show clock of them.

Hi Anuj
Utils_memAlloc(UTILS_HEAPID_DDR_CACHED_SR, FR_MODEL_SIZE, 32);
is get mem from LP-DDR2 ?

Hi,

Utils_memAlloc(UTILS_HEAPID_DDR_CACHED_SR, FR_MODEL_SIZE, 32);
is get mem from LP-DDR2 ?

It is from DDR3.

UTILS_HEAPID_OCMC_SR and UTILS_HEAPID_L2_LOCAL which is fastter?

UTILS_HEAPID_OCMC_SR is faster.

Anuj

Hi Anuj
pMemMgr.L2.pMem = Utils_memAlloc(UTILS_HEAPID_OCMC_SR,L2SRAM_SIZE,32);
is failed pMemMgr.L2.pMem=null
L2SRAM_SIZE =32*1024;
the code is used at sample_app\src\rtos\alg_plugins\framecopy\frameCopyAlgoLocalDma.c\Alg_FrameCopy_Create
pMemMgr.L2.pMem = Utils_memAlloc(UTILS_HEAPID_L2_LOCAL,L2SRAM_SIZE,32); is ok!

Hi,

Can you please check the vlue of all member variable of the below structure.
gUtils_memHeapObj[2].

Regards,
Anuj

Hi Anuj
you mean Vps_printf("gUtils_memHeapObj[0]=%d,gUtils_memHeapObj[1]=%d \n" gUtils_memHeapObj[0],gUtils_memHeapObj[1]); ?
where should i add this code ?

HI Anuj
OCMC_RAM1 0x4030_0000 0x4037_FFFF 512KiB 32bit Ex

OCMC_RAM2 0x4040_0000 0x404F_FFFF 1MiB 32bit Ex

OCMC_RAM3 0x4050_0000 0x405F_FFFF 1MiB 32bit

SO I can use 0x4030_0000 address as ocmc buf ,

Regards,
Anuj

HI Anuj
sorry i donot know how to do , could you help me .
Regards,
shuai

Hi,

pMemMgr.L2.pMem = 0x40300000;
And then use it.

Regards,
Anuj

HI Anuj
ocmc_buf=0x4030_0000 is failed i cannot EMDA data to that buf.
Regards,
shuai

Hi,

I did not understand your problem.

Can you explain in detail.

Regards,

Anuj

HI Anuj
pMemMgr.L2.pMem = 0x40300000;
then i use EDMA copy data from ddr to pMemMgr.L2.pMem, it have some crash , DSP core is crash.
i use pMemMgr_FR.L2.pMem = Utils_memAlloc(UTILS_HEAPID_L2_LOCAL, L2SRAM_SIZE, 32); program run normal.
so hoe can i use ocmc .

Hi,

Can you try with other OCMC(2&3) address.
Please make sure no one is touching that ocmc address.

Anuj

Hi： Anuj
I have thy OCMC(2&3) address ,also failed!

Hi,

Instead of doing EDMA copy can you try with simple memcpy and share your observations?

Anuj
