The nvram file is very specific to the hardware platform. Different platforms may use different values for xtalfreq. Common values are 38400, 37400, and some older designs used 26000. If the value is slightly wrong, you probably won't see any scan results. If the value is very wrong, the firmware will crash, and the driver will not load.
There may be other important things in the nvram, like the MAC address, like in the case of Nexus One. This is why the file is exported through /proc. In some devices, the MAC is burned into the chip. You can also put the nvram into /etc/wifi, but it is best to use the nvram that originally came with your device. -Howard On Jul 23, 9:41 am, Alim Akhtar <[email protected]> wrote: > please see drivers/staging/brcm80211/brcmfmac/README, links are there > to download the same. > though NVRAM is specific to the RF vender, but default also should > work at least for some extend. > > > > > > On Sat, Jul 23, 2011 at 10:01 PM, weihongcsu li <[email protected]> > wrote: > > Thanks Hamilton and Akhtar very much! > > I just could not google the nvram.txt.Do you have one? > > At the same time, I am trying to post msg,but there is something wrong > > with my adb shell and I could not install Droid Explorer,any suggestion? > > By the way,today I added the service to /etc/init.rc like > > "http://randyplaza.blogspot.com/2011/03/android-sourcebcm4329-porting....";. > > > 2011/7/23 Alim Akhtar <[email protected]> > > >> Posting your __error_mesg__ can give some more clue. > >> Looks like your NVRAM path is not correct. > >> AFAIR it should be in the same dir as firmware file. > > >> On Fri, Jul 22, 2011 at 8:04 PM, weihongcsu li <[email protected]> > >> wrote: > >> > Dear everyone, > >> > Hello,everyone!I am working to use bcm4329 on FRX05 , but wifi > >> > always > >> > turns on error.I really can't figure out what is the matter.Could you do > >> > me > >> > a favor?Thanks! > >> > Here are the details: > >> > 1.Environment: FRX05 From:http://xdandroid.com/, > >> >http://files.xdandroid.com/. > >> > 2.Phone is the Htc Raphael 800, but the wifi chip is the bcm4329. > >> > 3.What I have done: (1)Change dhcpcd.conf in "/etc/dhcp" and > >> > "system/etc/dhcp"; (2)Add fw_bcm4329.bin to "/etc/firmware" and > >> > "/system/etc/firmware"; (3)Modify wpa_supplicant.conf in "/etc/wifi" and > >> > "system/etc/wifi".
