OSD buffer alloc size

I use RGB way to filled the osd buffer.my problem is that when i alloc buff size is much bigger,for example the OSD content is "abcdefghijklmnopqrstuvwxyz",but when i Vsys_freeBuf the buffer ,it will stop down after the function Vsys_freeBuf ,

however when the OSD content is "abcde",it is litter length ,it will be free memory normally,and exit normally?

so that is why?

i found that when i alloc the buffer size is bigger than about 44928B,then the whole system will be down.

but my memory configure is following, i think 16MB is enough .why?

i just change the /dvr_rdk/mcfw/src_bios6/cfg/ti816x/config_1G_256MLinux.bld

SR1_SIZE                   = 199*MB;  // (- 2 MB)

DSP_DATA_SIZE              = 16*MB + 100*KB; // (+ 2 MB)

and the osd win parameter is about following:

chWinPrm->winPrm[winId].startX = osdParam->startX;//DEMO_OSD_WIN0_STARTX//100 ;
chWinPrm->winPrm[winId].startY = osdParam->startY;//DEMO_OSD_WIN0_STARTY + (DEMO_OSD_WIN_HEIGHT+DEMO_OSD_WIN0_STARTY)*winId;

chWinPrm->winPrm[winId].width = winWidth;
chWinPrm->winPrm[winId].height = winHeight;

chWinPrm->winPrm[winId].lineOffset = winWidth;

chWinPrm->winPrm[winId].globalAlpha = osdParam->globalAlpha;

chWinPrm->winPrm[winId].transperencyEnable = 1;//DEMO_OSD_TRANSPARENCY
chWinPrm->winPrm[winId].enableWin = osdParam->osdEnable;//DEMO_OSD_ENABLE_WIN;
chWinPrm->winPrm[winId].format = SYSTEM_DF_RGB24_888;

i do some othe test .whether the win width can not be over 320,so somewhere can change the max width vaulue,

i just find the macro

#define DEMO_OSD_WIN_MAX_WIDTH   (320)

but i can not find where it is used

This indicates you are corrupting the SharedRegion heap by writing beyond the allocated memory size

but when i create multiple the window width <= 320 ,it can be successful,so i think it is not memory enough.my every osd content will not be over 3K,but my memory configure is following:

i just change the /dvr_rdk/mcfw/src_bios6/cfg/ti816x/config_1G_256MLinux.bld

SR1_SIZE                   = 199*MB;  // (- 2 MB)

DSP_DATA_SIZE              = 16*MB + 100*KB; // (+ 2 MB)

i want to know how should set the osd window width parameters.because i do some test .when i set DEMO_OSD_WIN_WIDTH and the DEMO_OSD_WIN_PITCH_H to be both 720 or 224

they can run normally

but i set them to be 480 ,that can not run normally?

so why

i find  that i should  set the following parameters:

// set osd window max width and height
dspAlgPrm[0].osdChCreateParams[chId].maxWidth = EXAMPLE_OSD_WIN_MAX_WIDTH;
dspAlgPrm[0].osdChCreateParams[chId].maxHeight = EXAMPLE_OSD_WIN_MAX_HEIGHT;

but  when set the EXAMPLE_OSD_WIN_MAX_WIDTH = 1920,that video will be stop down.i want to know the max value of the both parameter?

tks

i found that i can set the max value of the EXAMPLE_OSD_WIN_MAX_WIDTH is just 720.then if over the max value,the system will stop following.In my opition the max value may be to 1920,so why?
