TI中文支持网比如我要用
ping = (Uint16*)MEM_alloc(DDR2HEAP,sizeof(Uint16)*roLength,32);函数
红色参数应该怎么填，好像是要填heap的位置，ccs3.3，不用bios。
HG：
memory section managermem_alloc第一个参数指定的是内存分配的位置，其值与系统内存heap的定义相关。
Q: Why users are not allowed to call MEM functions (MEM_alloc, MEM_stat etc) from an HWI or SWI?
Memory management functions ( MEM_alloc(), MEM_stat(), MEM_free()) are blocking calls. This is because the functions require the caller to acquire a lock to the memory before proceeding. In case the MEM functions fail to get a lock to the memory, there is a context switch. A call to a SWI or HWI routine should be non-blocking in nature and hence TI recommends that customer should not call MEM functions inside a SWI or HWI. In case the user makes blocking calls (MEM calls) inside a SWI or HWI, the behavior is not guaranteed. Making any blocking calls from a HWI or SWI can affect the real time response of the system.
