Wifi solution

[Dario]

Hello

I looking for wifi solutions using MQX TCP/IP stack.

I've seen that currently is on development a 802.11b WiFi ZeroG-based module for the Tower System.

http://www.freescale.com/webapp/sps/site/overview.jsp?nodeId=05521067406B48

I want to know if that solution would be ported for MQX and for wich Microcontroller and wich ZeroG mudule use.

It would be nice to have a Wifi device that connects to the MII interface directly, not via SPI. I'm not sure if such a device exists though...

I was hoping to see more development on this. 

Marc VDH, I found a wi-fi module that supposedly will connect to the RMII:

I think I might give this a try, unless someone knows of a farily well-developed solution for MQX on the Coldfire V2?

Interesting info, thanks!

Please keep us informed when you give it a try! :smileyhappy:

Hi,

Wifi card will most likely use ZG2101MC module and we are starting with MCF52259 MCU port.

Then all TWR MCUs should be supported.

Hi,

Is there any updated information or expected dates about the ZeroG module and integration with MQX? We are extremely interesting in adding wireless ethernet to our MCF52259 application.

Thank you.

Hi,

ZeroG Driver for MCF52259 Tower Board + ZeroG extension board should be released at beginning of November 2009.

The Wifi solution essentially requires a TCP/IP stack implementation over 802.11 b/g. Will the MQX/RTCS stack be upgraded to support TCP/IP over the ZeroG module on MCF5225x platform? The latest V 3.3.0 of MQX/RTCS does not support Wifi.

Yes, it will be in the HW level of the stack.

Hi,

how is this going?

I have just gotten out of a meeting and the directors have decided we need to add Wifi to out 52259.

Does anyone know how much this ZeroG module is worth? And is the driver ready for testing?

I have been looking at the Redpine Signals wifi module (RS9110-N-11-22), it seems quite simple, though, I would need to someone have the RTCS communicate over SPI. Is it difficult to get MQX's RTCS to talk over SPI to the Wifi module?

Hi,

ZeroG Wifi MQX driver is finished will be released soon.

ZeroG driver is part of current ENET driver. It uses standard SPI driver for communication with wifi module. 

RTCS stack is prepare to communicate with devices which implements standardized interface API. This API implements ENET driver. You can find enet driver source code in "mqx\source\io\enet\..." 

If you want to implement your custom ENET wifi driver you need to prepare custom service routines for your HW and pass them to ENET_PARAM_STRUCT initialization structure (bsp enet_ini.c file).

These routines must impelement similar functionality as current FEC and ZeroG driver provides (functions like send, shutdown, join, rejoin see ENET_MAC_IF_STRUCT, ENET_PHY_IF_STRUCT structs and "mqx\source\io\enet\mcf5xxx_fec"  sources).

Support for ZeroGwireless module in Tower system and also in MQX/RTCS V 3.5.0 (if it was previously available in V 3.4.0) appears to have been removed. There is no more mention of Wifi on Tower System Webpage. Is there any issue with it?

Hello,

ZeroGwireless seems to be bought by MicroChip, it could be explained that!

That may explain.

Does Freescale have any alternate plan form Wifi for Tower/MCF52259/MQX? Any schedule for its offering?

Best Regards,
