hi, all

I am sorry for my poor English.

 

I have two board, one is BF533 with 2 DM9000A network card(called BF533NET), the other is BF537 with one DM9000A network card(called BF537NET).

 

BF533NET use 2 DM9000A to transfer data, BF537NET use BF537'mac and DM9000A to transfer data.

 

When using BF533NET as Router, the throughput is more than 1M bytes/sec, but when using BF537NET, the throughput is only about 100K bytes/sec.(all other environment are the same)

 

I don't know why the result is like this, because the BF537mac's capability is much higher than the DM9000A.

What should I do ? thank you !

 

my uClinux is 2006R2-RC2.

Since we don't have any hardware including DM9000A, we can not help you to find the bug on our side.

 

And for the version of uClinux, please upgrade to our latest release 2008R1.5 to test again.

thank you Bryan

 

I want to know whether you have BF537 board with BF537'mac and any other network card.  you can use it as Router, and test  it's performance.

 

Thank you !

there are no addon cards that have been tested on a BF537 board

have you done any tests to see if each interface alone gets line rate ?

Thank you Mike,

 

I have done the test.

 

When I uesed BF537'mac or DM9000A(on BF537NET) only, the throughput is more than the DM9000A on BF533NET, but when I used BF537NET as Router, the throughput is slow.

 

I don't know why, than you !

Can you describe exactly what you mean when you say "as router"?

Thank you Robin.

 

My BF533NET has two DM9000A network card, my BF537NET has one DM9000A network card and BF537'mac. I used them as Router means: I used one network card as WAN port , use another network card as LAN port.

 

WAN port is a internet connection port. LAN port connets my lab's switch or hub.

 

I use BF533NET/BF537NET as Router means: My computer connect the LAN port and access internet through the WAN port.

That still does not tell me how to replicate something on the BF537-STAMP.

thank you Robin.

 

I don't think BF537-STAMP can replicate my experiment.

 

I have two computers called "computerA "and "computerB". I have BF533NET board and BF537NET board. Both BF533NET and BF537NET board have two network ports.

 

The IP of the computerA , computerB etc are:

 

computerA     192.168.139.200

 

computerB     10.0.0.200

 

BF533NET     WAN: 192.168.139.222    LAN:10.0.0.222

 

BF537NET     WAN: 192.168.139.222    LAN:10.0.0.222

 

First, I use BF533NET to connect computerA and computerB, ( computerA(192.168.139.200)<->BF533NET WAN(192.168.139.222)<->BF533NET LAN(10.0.0.222)<->computerB(10.0.0.200) ) I use computerA to download something from computerB, the throughput is more than 1M bytes/sec.

 

Second, I use BF537NET to connect computerA and computerB,( computerA(192.168.139.200)<->BF537NET WAN(192.168.139.222)<->BF537NET LAN(10.0.0.222)<->computerB(10.0.0.200) ) I use computerA to download something form computerB, the throughput is only about 200K byte/sec.

 

I don't know whether I describe it well. thank you !

 

I need help, thank you !

I think Blackfin USB-LAN EZ-Extender can help to replicate my experiment.

 

Use EZ-Extender can help BF537 EZ-KITE Lite has two network ports.

ww:

 

This still doesn't say if the problem is with the BF537 MAC driver, or with the DM9000A driver running on the BF537.

 

Do you have any way to isolate the problem?

Thank you Robin,

 

I don't know whether you have replicate the experiment. I think maybe it's a bug about BF537. BF537'MAC can not work with other network cards simultaneously.

Other people have plugged in the SMSC 91C111 card into the BF547, and ran both without issues. We have also done the same with the Microchip enc28j60. - and it also worked.

 

I don't know if there is anything we can do.
