Re: [linuxsh-dev] problems with PCI on SH7751 board

[Paul v. G. <pau...@ri...>]

The cards I tried are a Zcomax XI-625 (a miniPCI cards with a Harris
Semiconductor Prism 2.5 Wavelan chipset, supported by wlan-ng drivers), and
a IC Ensemble Envy24 audio card (supported by ALSA).

When loading the WiFi driver I get:

init_module: prism2_pci.o: 0.2.0 Loaded                                         
init_module: dev_info is: prism2_pci                                            
A Prism2.5 PCI device found, phymem:0x1000, irq:13, mem:0xa0001000

which looks fine but then when I enable the card I get:

# ./wlanctl wlan0 lnxreq_ifstate ifstate=enable                                 
hfa384x_drvr_start: Initialize command failed.                                  
hfa384x_drvr_start: Failed, result=46                                           
prism2sta_ifstate: hfa384x_drvr_start() failed,result=46                        

I've sent a mail to the wlan list to find out what error code 46 means. On
the Intel box, this error does not occur.

When I load the driver for the Envy24 card I get:

PCI: Setting latency timer of device PCI device 1412:1724 to 64
bad PC-like io name for port 0x33 at 0x8c01b108

This noncoherent setting was a the default I got. I believe it does have a
builtin bridge. Changing the setting doesn't help btw.

Attached is the contents of /proc/pci.

Thanks.
