Need second Ethernet (usb-Ethernet adapter) on 1808EVM

It looks like you probably haven't built the driver. Can you go to your Linux kernel source and do

make menuconfig

Select Device Drivers, Network device support, USB Network adapters, and select ASIX AX88xxx Based USB 2.0 Ethernet Adapters. That driver supports the Trendnet device you have.

Steve K.

Tried that (and a bunch of other things) before I even posted. I'd post the .config if I could figure how.

Brian

Hate it when this happens!  It is a lick on me!  Sorry for the noise.

I copied the uImage to my tftpboot dir but forgot that I made u-boot tftp something other than "uImage"!  It helps to specify the "right" file before you look stupid in front of everyone. I did a uname -a and was horrified that it wasn't the time/datestamp of what I just built and I had a "here's your sign" moment.

eth1 is now showing up in dmesg for the trendnet adapter on my 1808.

Again, sorry for the noise!

Now if I can just get the beagleboard to mount rootfs via NFS with the trendnet I'd be happy.  ;)

Brian

I still have issue with getting the kernel OTG support to build with the PSP mentioned in the first post.  The Trendnet as a 2nd nic is working fine now on the USB port.

Regards,

Brian

I have a few findings.  Out of the box, the kernel flashed on the board supports the OTG port only in host mode. To use it in host mode I connected one of those 5-in-1 cables where the ends are changeable. One end has Mini USB A while the other end has USB A Female. I was able to connect a USB memory stick and it was recognized.

I then re-compiled the kernel to support OTG mode. Type in make menuconfig, select Device Drivers, scroll down to and select USB Support. Select Inventra Highspeed Dual Role Controller. Then for Driver Mode select Both Host and Peripheral: Non-OTG Device. If you don't need Host mode you could select USB Peripheral (gadget stack). Then back on the USB Support page, scroll down to USB Gadget Support and select it. In the USB Peripheral Controller window make sure you have Inventra HDRC USB Peripheral selected. Then select the Gadget driver you want built. I built the Ether Gadget driver with RNDIS support. After building and booting the kernel I was able to connect the OTG port to my laptop with a standard USB cable. I had usb0 network devices on my laptop and on the board.

I hope this helps.

Steve,

Ah, that does help.  I'll have to try that.  Can I do the same kind of stuff with the 1808 OTG that you can do on the Beableboard like Ethernet over the USB cable for NFS, usbtty console  etc.?

On a different topic, I was able to get NFS going on my beagleboard using the trendnet.  I did a git pull of u-boot & kernel and that did the trickk so it must have been something with the version I was trying to use. 

Regards,

Brian

Hi Brian,

While I haven't tested it thoroughly on AM1808 but you should be able to do the same things with OTG as Beagle. The Ethernet Gadget driver works the same way so I don't see why the rest shouldn't.

Steve K.

After going back an looking at my .config I pretty much had what you said.

In Device Drivers->USB support-> Inventra Highspeed Dual Role Controller  I selected:

(X) Both host and peripheral:  USB OTG (On The Go) Device

I changed that to:

(X) USB Peripheral (gadget stack)

and it still results in:

 CC      drivers/usb/gadget/r8a66597-udc.o
drivers/usb/gadget/r8a66597-udc.c: In function 'r8a66597_probe':
drivers/usb/gadget/r8a66597-udc.c:1585: error: implicit declaration of function 'IS_ERR'

make[2]: *** [drivers/usb/gadget/r8a66597-udc.o] Error 1
make[1]: *** [drivers/usb/gadget] Error 2
make: *** [drivers] Error 2

This is with kernel in:
DaVinci-PSP-SDK-03.20.00.12/src/kernel/linux-03.20.00.12 built with CSL 2009q1-203

Which version of the kernel/PSP are you using?

Regards,

Brian

I'm still on 03.20.00.11, but I see your problem.  It looks like under the USB Gadget Support you have the incorrect core setting.  Go to Device Drivers -> USB Support -> USB Gadget Support -> USB Peripheral Controller. Make sure you have the Intentra HDRC USB Peripheral Controller selected:

     │ │        ( ) Renesas R8A66597 USB Peripheral Controller          │ │
     │ │        (X) Inventra HDRC USB Peripheral (TI, ADI, ...)         │ │
     │ │        ( ) Renesas M66592 USB Peripheral Controller            │ │
     │ │        ( ) Dummy HCD (DEVELOPMENT)                             │ │

From your compilation error, it looks like you have the R8A66597 selected.

Steve K.

In 3.20.00.12 under USB Gadget Support the Inventra option isn't there.  I think where the Renesas enters the picture is Gadget support defaults to:

(2)   Maximum VBUS Power usage (2-500 mA)                        │ │ 
  │ │          USB Peripheral Controller (Renesas R8A66597 USB Peripheral

I didn't catch that I could change "USB Peripheral Controller".  Wasn't obvious there was menu selection behind that selection in make menuconfig ... but when I discovered it I saw the menu as you stated in your last post and selected Inventra HDRC .... so now my build fails at:

[hutch@localhost linux-03.20.00.12]$ make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- uImage
  CHK     include/linux/version.h
  CHK     include/generated/utsrelease.h

make[2]: *** [drivers/usb/musb/musb_core.o] Error 1
make[1]: *** [drivers/usb/musb] Error 2
make: *** [drivers] Error 2

Clarification.  I should have edited my post when I said "In 3.20.00.12 under USB Gadget Support the Inventra option isn't there."  I said this wrong .. what I meant to say it isn't obvous that this choice is there the way make menuconfig presents it.  Maybe it was my terminal width but it wasn't obvious to me there was a menu behind the option I mentioned in my last post.

Hope I don't cause confusion for anyone else following this.
