Wifi problem in Jellybean os image for Cardhu dev kit

Hi, i found jellybean os image for Cardhu(Tegra Android Developer Pack 2.0r2) and installed it to the target board successfully. But, when i try to enable the Wi-Fi button, it doesn’t work.

This is the logcat file.

Do you have any idea?
Thank you very much.

this is a known issue - we’ll address this in the next releease

just flashed the 4.2 image (TADP 2.0r4), this problem still exists.

sorry, i was misinformed - this requires a new wifi module to fix. please contact your nvidia representative to get a new wifi module.

The WiFi worked for me with Android 4.0.4 installed. Now I have reflashed with Android 4.2 and WiFi doesn’t work. Are there any update files that can get this working under 4.2??


Hi AirWear,

Could you please provide me the detailed steps followed in flashing Android 4.2?

I just downloaded the latest developer pack and ran it. During the install it flashed the device. I have done this a few times, and each time WiFi does not work when I select 4.2, but if I select a much earlier version of Android, WiFi ends up working fine.

Any thoughts?

modify wifi_loader.sh

/system/bin# cat wifi_loader.sh
if [ -z $(getprop ro.boot.commchip_id) ]; then
setprop wifi.commchip_id 2
echo “commchip_id is not set, so setting it to 4330”
echo “setting user configured value of WiFi chipset”
setprop wifi.commchip_id 2
