Just to be clear, there is a lot of additional output when I try to run the calibrator command. I can post it all if it would be helpful.

Have you tried running the commands from this section: http://processors.wiki.ti.com/index.php/WL12xx_NLCP_Calibration_Process#Calibration_for_R4_SP1_and_earlier_.28AM-SDK-05.03.00.01.29

Since your using a kernel based from the 04.06.00.02 SDK

Jonathon,

You're correct, I was using the commands from the wrong section. Unfortunately, following the correct commands leads to a similar result:

root@am335x-evm:~# calibrator set ref_nvs /usr/share/ti/wifi-utils/ini_files/127x/TQS_S_2.6.ini

The path to input output file not provided, use default (./new-nvs.bin)
root@am335x-evm:~# cp new-nvs.bin /lib/firmware/ti-connectivity/wl1271-nvs.bin
root@am335x-evm:~# ifconfig wlan0 down
root@am335x-evm:~# rmmod wl12xx_sdio

Hello Jesse,

We attempted to run the calibration tools as well, and have seen the same result as you. We are looking into the problem, but would like to point out that the wireless should work on the board out of box. The way to configure and connect to a wireless network can be seen at this link: http://support.criticallink.com/redmine/projects/arm9-platforms/wiki/USB_WiFi_Configuration#Configure-Linux-to-Use-and-Connect-to-WiFi-Network

For what reason are you attempting to run the calibration tools?

Thanks for the information. Just to be clear, I am not having trouble using wireless on the evaluation board. I am only having trouble running the wifi calibration tool.

My understanding is that the wifi calibration tool needs to be run on each board at manufacturing. I have been trying to run the calibration tool on my custom board and I keep getting errors. I thought I'd test the calibration tool on the eval board to see what I'm doing wrong, but I ran across the same issue.

Greg,

Have you been able to get the wifi calibration tool running on the evaluation board?

Thanks
Jesse
