Message: 50381    The wikidoc only talks about configuring and building this support as a module.  Is this mandatory, so that you can pass in arguments like g_ether host, etc?

Can I assume that I could build it in if I had the appropriate environment variables set?

Message: 50384    Bill,

I didn't try built-in g_ether, because we set some MAC address when insmod.

But it should be ok for you to try it, please share your result with us.

Thanks

-Bryan

Message: 50387    How do I enable USB_B5 connector for my Ethernet over USB test/demo?

I intended to try this initially with the BF537-STAMP board using the ADDS-USB-EZEXT1.  I have the cypress USB working.  I think based on what  see in the schematics that I should be able to just pull jumper 12 and change to SLAVE mode.  Does this also change the connector to the USB_B5? I assume USB_A5 and USB_B5 are not active at the same time and I have only used USB_A5 (host) in the past.

Sorry for the question, but of all the ADI development/evaluation and ADD ON daughter boards I have.   I only have one ADDS-USB-EZEXT1 and am a little uncertain and don't want to damage the board.

I have several (at least 4) of the ADZS-USBLAN_EZEXT daughter boards that I was using on the BF561-EZKIT, but these don't seem to be compatible at all with the BF537-STAMP.

Message: 50393    I decided to pull jumper 12 and give it a try.  Once the sparks stopped and the smoke cleared and I made sure my dog was no longer on fire I captured the standard output.

(Here is the what I really experienced

Pulling jumper 12 on the USB-ADD-ON card doesn't seem to be the only thing I have to do. I was trying to use my mega-multimedia BF537-STAMP board where I had console enabled, of course pulling jumper 12 means I lost my host USB and had no HID, so I removed console.  Then I had a peripheral 13 conflict apparently with the LCD, so I disabled graphics support altogether.  Then I still had a GPIO 6 conflict with the ad1836 daughter board, so I disabled sound support altogether.

After this, I no longer experienced any sort of stack dump, but the SL811 Slave still has errors reading and writing. I gather this excerpt is the problem:

net2272: PLX NET2272 USB Peripheral Controller

net2272: irq 57, mapped mem 20300000, chip rev 00f9

net2272: running in 16-bit, no byte swap local bus mode

net2272: version: 2005 Sept 8

net2272: 2272 not found!

net2272: unbind

So all in all no luck yet and I am not sure what to do next.

Any thoughts?

Here is the first output with all my multi-media drivers in tact:

Bill,

I remember I noticed this before:

(plug and play can be often be plug and pray - embedded developers handing should be aware...)

1) There is NO USB Device driver for the SL811HST. The feature on the SL811, ISP1362 USB combo Card is JUST a feature (this applies for both controllers), not a tested option - however electrically it's considered as functional and bullet proof, as long as you set/remove the right jumpers.

2) The only devices where we feature USB Device functionality is PLX2272 aka NET 2272 (USB_LAN externder) or the BF548/BF527 on-chip USB peripheral.

This card should also work with the BF537-STAMP aka more or less EZkit. (Check the jumper/switch options)

Message: 50402    Michael - I did notice that the USB_LAN extender had the NET2272.  I guess I thought the USB was a 'standard' and 'ethernet' was a 'standard' and I didn't expect a special chip would be necessary to get ethernet over USB to work.

I did swap over to a BF561-EZKIT with the extender card in place and it didn't even attempt to probe for the NET2272.  It didn't work either.  Even if I didn't have the dip switches and/or jumpers set correctly I thought it should at least look and tell me it failed to find NET2272 like the software did on the BF537-STAMP.  I set the same gadget configuration that I used on the BF537-STAMP.

I initially tried with the 2.3 BOM of the BF561-EZKIT, but since there has been some reported power issues, I also tried the 2.6 BOM with no better results.

I am now swapping the USB cards and putting the USB_LAN extender onto my BF537-STAMP board and see if that works.

I don't care where or how I get it to work, but I simply must get it to work by tomorrow. Your help as always is appreciated.

Bill

Message: 50406    No problem.  I have it working now on the BF537-STAMP with the USB_LAN.  Like I mentioned before I had to disable all other daughter cards (sound and graphic) to avoid conficts, but it is up and running.

I was using the exact same daughter board on the BF561-EZKIT which didn't work (although like I mentioned it didn't even probe for the NET2272 - perhaps I overlooked a config setting?).

Anyway, one more milestone behind me.

This is all new to me and I am not sure what to expect when I have an eth0 and a usb0 so I bring down the eth0 just to avoid confusion.  Is it possible to have both of these enabled and up at the same time?  I would assume so, since if I'm not mistaken VPN tunnels work in tandem with other ethernet devices without conflict.

Thanks for your help,

Bill

Message: 50577    Mike H.

Do you think the reason I got this to work on the BF537-STAMP and not the BF561-EZKIT might be related to the SMSC91111 driver on the BF561?

I say this because both the regular Ethernet and the USB are both on the add on card.  The BF537-STAMP board however has the built in MAC in the DSP and only only a phy connector, whereas the BF561-EZKIT has the SMSC91111 chip and I need regular internet in order to boot the uClinux using TFTP.  So on the BF561-EZKIT I was building both regular Ethernet and Ethernet over USB and perhaps this caused the problem/conflict?

Not that this is overly important at the moment, but I would like to understand the difficulties I encountered trying to get this to work on the BF561-EZKIT.
