Re: [OpenWrt-Devel] AR7240 switch // was: TP-Link TL-WR741ND: broadcasts on ethernet not reaching CPU

2010-03-01 Thread Dennis Bartsch 

Hello list,

finally the switch in the TP-Link TL-WR741N(D) (and probably other devices 
based von AR7140) is not blocking broadcasts any more and thus allows to get an 
IP via DHCP.

But my question is left to be answered. Does this bridge which is created over 
the LAN-ports really mean that the CPU is doing the bridging?? Performance-wise 
this would be a bad behaviour.

Regards
Dennis

Today in revision 19927 switch support for AG7240 has been committed. I'll try 
that. Buildroot is running at the moment.

could be an explanation.

What I understand from the commit 19930 is, that bridging is now done in CPU on 
this switch? Am I right?

[OpenWrt-Devel] TP-Link TL-WR741ND: broadcasts on ethernet not reaching CPU

2010-02-20 Thread Dennis Bartsch 

Hello,

can anyone comfirm that on the TP-Link TL-WR741ND broadcasts are not received 
on LAN ports? I got aware of it when I had not gotten an IP adress through 
DHCP. Then I generated other broadcast. But a quick sniff with tcpdump didn't 
show these broacasts. Unloading firewall didn't help. Under these circumstances 
it is clear that DHCP could not work.

At the moment rev 19598 is flashed.

Regards
Dennis

Re: [OpenWrt-Devel] [PATCH] routerstation and madwifi

2009-06-30 Thread Dennis Bartsch 

Hello,

the solution is as simple as it was discussed here. By compiling madwifi 
without compression capabilities the routerstation booted nicely with 2 atheros 
cards.
I assume that the hardware compression engine doesn't work together with 4byte 
DMA transactions which had to be comfigured to get the old a/b/g atheros chips 
on AR71xx

I attached a patch which makes compression an optional parameter in menuconfig.

I don't know whether this 3.3V output is intended to be used like that but it 
works.
I'm cusious whether 3.3V is enough to supply a MAX232 (or derivates) but is 
definately enough for a MAX3232 (or derivates), as I use it this way.

[OpenWrt-Devel] freezes on alix with madwifi

2009-02-07 Thread Dennis Bartsch 

hello list,

in recent trunk revisions (14288, 14426) on an alix I have problems with a 
freezing system everytime I restart networking, apply network config or even at 
reboot with an atheros card installed.
without the card I get to read a "wlanconfig: ioctl: No such device" where the 
board freezed with the card. this leads me to the conclusion that this is a 
madwifi related problem. could you please look over it?

king regards

[OpenWrt-Devel] [PATCH]support for cs5536 IDE

2009-02-07 Thread Dennis Bartsch 

hello list,

with recent releases alix boards won't boot from CF card anymore.

attached is a patch for special support of the cs5536 IDE controller to fix the 
broken support for alix and probably other geode LX boards with kernel 2.6.28.2 
.
it is tested to apply against 14426 and 14430.

[OpenWrt-Devel] alix hangs with madwifi countrycode set

Hello list

I build a fresh kamikaze trunk checkout rev 12763 an flashed it onto an alix 
2c3 with a wistron cm9 installed.

The trouble begins, when I add a "countrycode=276" to /etc/modules.d/50-madwifi 
as I always did.
The board hang completely ... no oops, no reaction on serial console and no 
ping. The last lines I can see are:
