I use DVRRDK4.0 package, the total ddr size is 2GB, I use config_2G.bld. The ddr memory map is as following,
/* FIRST + SECOND 512MB */
var SR1_SIZE = 220 * MB;//220 * MB;
var VIDEO_M3_CODE_SIZE = 3 * MB;
var VIDEO_M3_BSS_SIZE = 23 * MB;
var VIDEO_M3_DATA_SIZE = 3 * MB;
var DSS_M3_CODE_SIZE = 2 * MB;
var DSS_M3_BSS_SIZE = 20 * MB;
var DSS_M3_DATA_SIZE = 6 * MB;
var DSP_CODE_SIZE = 5 * MB;
var DSP_DATA_SIZE = 160 * MB;//160 * MB;//110 * MB;
var SR2_FRAME_BUFFER_SIZE = 550 * MB;//550 * MB;//600 * MB;
var VIDEO_M3_EXCEPTION_CTX_SIZE = 128*KB;
var VPSS_M3_EXCEPTION_CTX_SIZE = 128*KB;
var SR0_SIZE = 22 * MB + 768 * KB;
var HDVPSS_DESC_SIZE = 2 * MB;
var HDVPSS_SHARED_SIZE = 2 * MB;
var NOTIFY_SHARED_SIZE = 2 * MB;
var REMOTE_DEBUG_SIZE = 1 * MB;
var SHARED_MEMORY_SIZE = 2 * MB;
/* THIRD 512MB */
var TILER_SIZE = 256 * MB;
var SR3_FRAME_BUFFER_EXTRA_SIZE = 256 * MB;
/* LAST 512MB */
var LINUX_SIZE = 512 * MB;
My systemHeap is 120M, if I decrease the size, the dsp run error, its print information is DSKT2_createAlg failed.
var HeapMem = xdc.useModule('ti.sysbios.heaps.HeapMem');
var heapMemParams = new HeapMem.Params;
heapMemParams.size = 0x07800000;
heapMemParams.size = heapMemParams.size;
heapMemParams.sectionName = ".systemHeap";
var heap0 = HeapMem.create(heapMemParams);
Memory.defaultHeapInstance = heap0;
My boot parameter is as following,
mw.b 0xC1000000 0xFF 0x2000000
tftp 0xC1000000 ramdisk.gz
nand erase 0x009c0000 0xc820000
nand write 0xC1000000 0x009c0000 0x2000000
the first group,
setenv bootcmd 'nand read.i 0xC1000000 0x00580000 0x300000;nand read.i 0xC2000000 0x009c0000 0x2000000;bootm C1000000'
setenv bootargs 'mem=512M console=ttyO2,115200n8 earlyprintk root=/dev/ram0 rw initrd=0xC2000000,40M ramdisk_size=450000 ip=192.168.1.181:192.168.1.33:192.168.1.1:255.255.255.0::eth0:on notifyk.vpssm3_sva=0xbfb00000 vmalloc=500M ddr_mem=2048M debug'
the second group,
setenv bootcmd 'nand read.i 0xC1000000 0x00580000 0x300000;nand read.i 0xC2000000 0x009c0000 0x2000000;bootm C1000000'
setenv bootargs 'mem=512M console=ttyO2,115200n8 earlyprintk root=/dev/ram0 rw initrd=0xC2000000,40M ramdisk_size=450000 ip=192.168.1.181:192.168.1.33:192.168.1.1:255.255.255.0::eth0:on notifyk.vpssm3_sva=0xbfb00000 vmalloc=476M ddr_mem=2048M debug'
When I use the first group boot parameter, when load dsp firmware, it will run error.
