[leaf-user] Re: DWL 520 rev E work around

[Jim Munro]

Looks like the trouble traces to grep(ing) past a certain byte offset in
/proc/net/hostap/$1/debug.  As a work around I created a directory wlan0 in
/etc/firmware/hostap and modified some lines in 
/etc/network/if-pre-up.d/hostap-utils.
Also had to tweak grep line in load_secondary from pri_only=1 to pri_only=0
Could the grep thing be a bug in the OS.  Not a pretty solution but the NIC 
loads the firmware OK and radio passes data.

Likely a better coding fix can be found.

load_primary()
{
       echo "load primary...."
       if [ ! -d /proc/net/hostap/$1 ]; then
               echo "Host AP driver data for device $1 not found in 
procfs."
               return 1
       fi

cp /proc/net/hostap/$1/debug /etc/firmware/hostap/$1/debug

       if grep -q no_pri=1 /etc/firmware/hostap/$1/debug; then
               echo "Downloading primary firmware $2 to interface $1"
               $PRISM2_SREC -gs $1 $2
               $PRISM2_SREC -gp $1 $2
       fi

       return 0
}

load_secondary()
{
       echo "load secondary ...."
       if grep -q pri_only=0 /etc/firmware/hostap/$1/debug; then
               echo "Downloading secondary (station) firmware $2 to 
interface $
               $PRISM2_SREC -rp $1 $2
       fi

       return 0
}

Hi Eric,

Thanks for the help.  I have been able to get the IF up manually with 
prism2_srec using
pm010102.hex and rf010800.hex and then doing an ifup wlan0 (also passes 
data :).  It appears that these lines of code in 
/etc/network/if-pre-up.d/hostap-utils
may not be executing.  I stuck some debug in the script and the download 
primary and secondary procedures are being entered. wlan0 also appears in 
/proc/net/hostap/

------>        if grep -q no_pri=1 /proc/net/hostap/$1/debug; then
               echo "Downloading primary firmware $2 to interface $1"
               $PRISM2_SREC -gs $1 $2
               $PRISM2_SREC -gp $1 $2

------>        if grep -q pri_only=1 /proc/net/hostap/$1/debug; then
               echo "Downloading secondary (station) firmware $2 to 
interface $
               $PRISM2_SREC -rp $1 $2

Hello Jim,

It indeed looks like the primary firmware is loading fine but there is a
problem with the station firmware. Are you sure the station firmware is
not corrupted?
