[Madwifi-devel] latest madwifi on 5200 ppc

[Sergei P. <spo...@em...>]

Hi all,

I'm trying to bring up the Proxim Orinoco 11b/g PC Card (AR5212 chip) on 
custom MPC5200 based board with
pcmcia cardbus controller. Customer claims that he tried WLAN and other 
cards on this and all works well.

Successfully built the latest madwifi built for powerpc-be-eabi.
Loaded ath_pci with modprobe and it shows:

ath_pci: 0.9.4.12 (EXPERIMENTAL)
ath0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps
ath0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps 
24Mbps 36Mbps 48Mbps 54Mbps
ath0: mac 5.9 phy 4.3 radio 4.6
ath0: 802.11 address: 00:20:a6:51:f4:eb
ath0: Use hw queue 0 for WME_AC_BE traffic
ath0: Use hw queue 1 for WME_AC_BK traffic
ath0: Use hw queue 2 for WME_AC_VI traffic
ath0: Use hw queue 3 for WME_AC_VO traffic
ath0: Atheros 5212: mem=0x44800000, irq=6


ifconfig ath0 up seems starts station scan. iwconfig seems shows 
reasonable data:

bash-2.05b# iwconfig ath0
ath0      IEEE 802.11  ESSID:""
          Mode:Managed  Frequency:2.462 GHz  Access Point: FF:FF:FF:FF:FF:FF
          Bit Rate:1 Mb/s   Tx-Power:50 dBm   Sensitivity=0/3
          Retry:off   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality=0/94  Signal level=-95 dBm  Noise level=-95 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

bash-2.05b#


The problem is the card cannot find the station, even if I  set ESSID, 
channel and AP's macaddr manually.
The station is fixed on channel 11 and when I set up the card to this 
channel with 'iwconfig ath0 channel 11'
I can see a lot of incoming Rx packets using 'athdebug recv_desc'. Also 
the 'ath0: hardware error; reseting'
appears periodically.

'iwlist ath0 scan' returns no 'scan results'.

I digged a little and found that none of incoming Rx packets are 
accepted because of the status returned
by ath_hal_rxprocdesc() is HAL_EINPROGRESS (if_ath.c, ath_rx_tasklet()):
...
       status = ath_hal_rxprocdesc(ah, ds,
                bf->bf_daddr, PA2DESC(sc, ds->ds_link));
#ifdef AR_DEBUG
        if (sc->sc_debug & ATH_DEBUG_RECV_DESC) {
            ath_printrxbuf(bf, status == HAL_OK);
            printk("status: %#x\n", status);//psl
        }
#endif
        if (status == HAL_EINPROGRESS)
            break;
...


I'm pretty stuck on this and any help will be greatly appreciated.

Thanks in advance,

Sergei
