Hi,
I have ported our linux wlan driver on to the OMAP L138 board to support our wi-fi card. It is working perfectly and am able to connect to an access point with that board. Our card is interfacing through SDIO slot. Now I have the following doubts:
1) I am using iperf to measure the throughputs and I am getting very low throughputs than our card could give. I am using 'arago-am18xx-demo-image-da850-omapl138-evm' file system and DaVinci-PSP-SDK-03.20.00.14 kernel. Is there any change, I should make regarding sdio drivers for good throughputs??? Are there any updated versions of the filesystem or the kernel I am using?? The round trip time for the ping is also very high. It is about 16ms
2) It is mentioned that NAND, NOR and SDIO are multiplexed and so we cant use them all at a once(mentioned not to enable all in kernel config). Currently I am using NFS server, TFTP server to load uImage and my target file system on to the board. Then using the sdio slot for our wi-fi card. Is there a way, I can flash my uImage and file system on to NAND or other storage media and use my wi-fi card to access wi-fi. Also the documentation doesn't give any procedure to boot file system from sd card and copy it on to SDRAM for stand-alone usage.
Someone please help me regarding this!!!

Rupesh
