嗨，大家好
最近在测试OMAPL138测试板，我用的DVSDK版本是dvsdk_omapl138-evm_04_03_00_06_setuplinux
DVSDK里面Codec Engine例子默认的内存映射如下：
0xC0000000 .. 0xC1FFFFFF ( size 32MB): Linux: booted with MEM = 32M
0xC2000000 .. 0xC2BFFFFF ( size 12MB): CMEM: shared ARM/DSP I/O buffers
0xC2C00000 .. 0xC2EFFFFF ( size 3MB): SDRAM
0xC2F00000 .. 0xC2F00FFF ( size 4KB): RESET_VECTOR: reset vectors
0xC2F01000 .. 0xC2FFFFFF ( size 1020KB): DSPLINKMEM: memory for DSPLINK
0xC3000000 .. 0xC3FFFFFF ( size 16MB): RESET_VECTOR: reset vectors
我的开发板内存是128MB，于是我想给Linux 96MB内存，使得最终内存分配如下：
0xC0000000 .. 0xC5FFFFFF ( size 96MB): Linux: booted with MEM = 96M
0xC6000000 .. 0xC6BFFFFF ( size 12MB): CMEM: shared ARM/DSP I/O buffers
0xC6C00000 .. 0xC6EFFFFF ( size 3MB): SDRAM
0xC6F00000 .. 0xC6F00FFF ( size 4KB): RESET_VECTOR: reset vectors
0xC6F01000 .. 0xC6FFFFFF ( size 1020KB): DSPLINKMEM: memory for DSPLINK
0xC7000000 .. 0xC7FFFFFF ( size 16MB): RESET_VECTOR: reset vectors
按照论坛及文档说明，我修改了三个地方：
首先是uboot参数，将mem=32M改成mem=96M。
其次是加载CMEM模块时指定的物理地址，将phys_start=0xC2000000 phys_end=0xC2BFFFFF改成phys_start=0xC6000000 phys_end=0xC6BFFFFF。
最后是CE Server内存分配配置文件，我的配置：
var mem_ext = [
{
comment: "SDRAM: off-chip memory for application code and data",
name: "SDRAM",
base: 0xC6C00000,
len: 0x00300000,
space: "code/data"
},
{
comment: "RESET_VECTOR: off-chip memory for the reset vector table",
name: "RESET_VECTOR",
base: 0xC6F00000,
len: 0x00001000,
space: "code/data"
},
{
comment: "DSPLINK: off-chip memory reserved for DSPLINK code and data",
name: "DSPLINKMEM",
base: 0xC6F01000,
len: 0x00100000 - 0x1000,
space: "code/data"
},
{
comment: "DDRALGHEAP: off-chip memory for dynamic algmem allocation",
name: "DDRALGHEAP",
base: 0xC7000000,
len: 0x01000000,
space: "code/data"
},
];
请问除了这三个文件，我还需要修改其他的么？
