MQX4.0 and TWR-WIFI-AR4100 patch?

[fireblade]

i just obtained a TWR-WIFI-AR4100 and instructions says to install an "enablement patch for MQX" but there are only versions for MQX 3.6.2 and 3.7 listed in downloads (http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=TWR-WIFI-AR4100&fpsp=1&tab=Design_Too...)

does this mean that it is already enabled in MQX4.0 or that no patch exists?

Hi Sebastian,

are you using your WiFi application in "adhoc" or in "managed" mode?

Hi Thomas,

I tried only managed

Sebastian,

I'm using the TWR-K60N512 board with the same application and it's working, but only,when I make a power up reset. If I just push the reset button with power left attached, I'm getting the same error massage as you get. I have no idea, why, but may be, that information helps!?

Regards

Thomas

Hi,

I am running mqx 3.8 and k60f120m. I went through the above steps to be able to use the AR4100, except

change from:

1. a_netbuf_ptr->native.FREE = (_pcb_free_fn)freefn; 

change to:

1. a_netbuf_ptr->native.FREE = (PCB_FREE_FPTR)freefn; 

which seems to be MQX 4.0 specific. Everything compiles fine, but ipcfg_init_device returns error 0xA4FF (ENET_ERROR). I checked if WriteBufferSpace reads EXPECTED_MAX_WRITE_BUFFER_SPACE, and it does, and I removed the

ioctl (pCustCxt->spi_cxt, IO_IOCTL_SPI_SET_CS, &input)) 

line from custom_hw_init().

Do you have any idea as to what I could do next to make it work? Or perhaps where to search for info?

Thanks,

Sebastian

Sebastian,

this was specific to MQX 4.0 spi driver. MQX 4.0 has different SPI driver than MQX 3.8 / 3.8.1. As far as I know Atheros have their own port for MQX 3.8, so try contacting them. With MQX 3.8 you would need that SET_CS ioctl. You code stops exactly at the place where it checks if spi communication with the wi-fi chip is working. If you connect oscilloscope on spi signals you will see problems (no chip select asserted I guess).
