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
