Problem printing via putty of warp v3

Hi,

I am working with 802.11 reference design currently, but I meet some problems.

The first thing is about printing information via putty, when I configure other reference design(like OFDM), it can display normally. But when I configure the board working as AP or STA, it displays some illegal code. I have correctly set the putty configuration (like serial port, speed), as I attached below, it turns to wrong when I configure the board as STA.

Does anybody know how is it?
Thanks a lot for your help.

The 802.11 Reference Design configures the UART interfaces for 115200 bps. The default design on the SD card (i.e. the design that prints "WARP v3 UART & User IO Test") configures the UART for 57600. Try changing your Putty serial port speed to 115200.

Re: Problem printing via putty of warp v3

Thank you for your quick reply. It works.

And I have another question right now, my STA(a WARP board) has successfully joined a router, but I can't check the IP address of STA, I can only see the MAC address of it. In my work, my STA is connected to PC via Ethernet cable, smart phone connected to router too. Since I can't get the IP address of STA, how can I ping from STA with smart phone in this LNA?

Thanks a lot.

Re: Problem printing via putty of warp v3

The 802.11 Ref Design implements a layer-2 (MAC layer) bridge. The AP and STA nodes do not have IP addresses for their ETH A interfaces. The AP/STA code only examine MAC addresses in ETH A traffic to determine whether packets should be encapsulated and transmitted over the wireless interface. In order to transmit ping (ICMP echo request/response) packets over the wireless link, you must connect the AP and STA ETH A interfaces to other devices. A typical setup is to connect the AP to an Ethernet switch (on a network with a DHCP server and internet access) and connect the STA directly to a PC. The PC will see a normal Ethernet connection even though its traffic will bridged to the AP's wired network via the AP-STA wireless link.
