loadmodules.sh内容如下：

麻烦帮忙看下
Shine：
请问板子上面有多大的DDR？分配给linux多少内存？剩下的多少给cmem用的，如果分配的cmem的内存大于实际留下的，就会报无法分配的错误。用cat /proc/cmem查看一下mem模块是否有正确的分配pool给系统，请看下面的wiki网站。http://processors.wiki.ti.com/index.php/Changing_the_DVEVM_memory_map#CMEM:_Contiguous_Memory_Allocator

回复 Shine:
用的是dm6467,256MB的DDR
分配给linux120MB
8MB给cmem
cat /proc/cmem 有按配置文件分配pool。
求指导

内核版本是多少？下面有个FAQ。Q: Can CMEM_getPhys() be used to translate any virtual address to its physical address? http://processors.wiki.ti.com/index.php/CMEM_Overview#CMEM_FAQ

回复 Shine:
内核版本是2.6.32-rc2-davinci1
用的是dvsdk_3_10_00_19
