## Media: video
|

|
|
1、psram range used for media: 0x60000000 - 0x60AFFFFF
|
|||
|
|
psram_based_addr: 0x60000000
|
|||
|
|
according encode frame resolution to allocate psram block, please reference components/media/frame_buffer.c
|
|||
|
|
|
|||
|
|
## Psram: config
|
|||
|
|
注意：此工程默认是在16M的psram板子上使用
|
|||
|
|
因为其cp0上psram的配置如下：
|
|||
|
|
CONFIG_PSRAM_HEAP_BASE=0x60B00000
|
|||
|
|
CONFIG_PSRAM_HEAP_SIZE=0x200000
|
|||
|
|
CONFIG_PSRAM_HEAP_CPU0_BASE_ADDER=0x60B00000
|
|||
|
|
|
|||
|
|
cp1上psram配置如下：
|
|||
|
|
CONFIG_PSRAM_HEAP_BASE=0x60D00000
|
|||
|
|
CONFIG_PSRAM_HEAP_SIZE=0x300000
|
|||
|
|
CONFIG_PSRAM_HEAP_CPU0_BASE_ADDER=0x60B00000
|
|||
|
|
|
|||
|
|
因为8M psram最大地址为0x60800000,明显上面是超过该地址的
|
|||
|
|
16M psram的最大地址为0x61000000
|
|||
|
|
从上可知：
|
|||
|
|
psram在cp0上的heap起始地址为0x60B00000，heap大小为2Mbyte
|
|||
|
|
在cp1上heap的起始地址为0x60B00000+2Mbyte=0x60D00000，大小为3Mbyte
|
|||
|
|
|
|||
|
|
如果要修改为8M psram上使用
|
|||
|
|
cp0的配置：
|
|||
|
|
CONFIG_PSRAM_HEAP_BASE=0x60700000
|
|||
|
|
CONFIG_PSRAM_HEAP_SIZE=0x80000
|
|||
|
|
CONFIG_PSRAM_HEAP_CPU0_BASE_ADDER=0x60700000
|
|||
|
|
|
|||
|
|
cp1的配置：
|
|||
|
|
CONFIG_PSRAM_HEAP_BASE=0x60780000
|
|||
|
|
CONFIG_PSRAM_HEAP_SIZE=0x80000
|
|||
|
|
CONFIG_PSRAM_HEAP_CPU0_BASE_ADDER=0x60700000
