Other Parts Discussed in Thread: AM1808, WL1271

Hello

I'm testing the wifi speed about wl1271 on am1808 evm board. I compiled the linux kernel(2.6.33-rc4) in sdk version 4.0.1.0 and the wifi module wilink. from the debug info I can see that all read/write process are not use the dma and the speed looks not good(about 13Mbits/s). 

As my aim wifi speed is about 25Mbit/s and I want to use dma to access data. Please help me that if I can reach my aim and what can i do to make that.

thanks very much.
