总是提示内存溢出还是什么地址范围的问题，怎么设置呢

可以加载，但又有一个问题

我的sh文件如下：

# Default Memory Map

# Start Addr Size Description

# -------------------------------------------

# 0x40200000 60 KB CMEM (internal memory, see comment below)

# 0x80000000 80 MB Linux

insmod cmemk.ko phys_start=0x85000000 phys_end=0x85FFFFFF pools=20x4096,10x131072,2x1048576,1x153600,1x614400,1x2621440

而且加载的时候，也加载成功了，

运行 320x240 等小像素的图像处理，可以成功，但做到1280*1024，就说没有1208*1024*sizeof（char）*2=2621440，信息如下：
