if i understand you right, you cannot define a buffer, which is big enough; for example: 

char buffer;

so if i'm right you should try to use the malloc function ; in this case (*edit* for buffers greater than 1mb) you need to enable a kernel option to do so (for big portions of memory): 

processor type and features --> allow allocating large blocks....

Thank you helmchen, you have understand me right.

Can I ask two more questions?

1, I have seen the option in the configure interface, but I wonder the kernel take use of what for the large blocks?

2, Can I just use the limited buffer to carry out large data transmission? For example, send several times?(I have tested, but still can&#39;t find good methods..)

Thanks again http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif
