I now have a brand new platform - same basic design as before but with a DM3730 instead of the DM8148. I've tried a couple of off-the-shelf kernels (3.0.0 and 3.3.0) with it, with mixed results. With 3.3.0 I could not get the device to associate with the AP. It would get started and then the wl1271 stopped talking and the process failed. With 3.0.0, I can get it to work reasonably well. However, I still have to go through the manual steps to get it to associate. Anything other than the process below causes the wl1271 to reset and die... I also cannot shut the device down and restart it. Attempts at a restart cause the wl1271 to lock up and I have to reboot to recover. Only these steps work for the initial association: # ifconfig wlan0 hw ether 0:1:2:3:4:5 # ifconfig wlan0 up # iw wlan0 scan # ifup wlan0 Note: my AP is using WPA2 so I'm also running wpa_supplicant I'm going to try using the latest compat-wireless, using the 3.0.0 kernel as overall it is more stable on this platform. I also plan to experiment a bit with the Panda (OMAP4) as it has the same peripherals (and I assume that it works?) What can I do to make this work better? What data need I provide to help diagnose the failures?
