I had wview working beautifully on the 2.7 beta version of openslug. For some bizare reason, I got it into my head to upgrade the slug. I did everything from scratch.

So - I have 3.10 beta working just fine but cannot get communications with vpro. I seem to recall that the cp2101 module needed to be loaded in the 2.7 version, but that module will not install with ipkg on 3.10. It complains:

ERROR: cannot satisfy the following dependencies for kernel-module-cp2101: kernel-image-2.6.12.2

The os recognizes the usb when it is connected and designates it as /dev/usbdev2.3 but generates errors like the following.

daemon.err udevd-event [1450]: match_rule : MODALIAS id deprecated, use ENV{MODALIAS} or SYSFS{modalias} instead
although I have seen these errors for other devices (like eth) that work.

vpconfig /dev/usbdev2.3 show just gives
VP Console Wakeup failed - retry .....

Any suggestions?

Thanks in Advance. This is an awesome program.....

Hi

I've just had a go at building the cp2101 module for 3.10-beta. It's at http://www.scorpiocomputing.com/weather/ipk/kernel-module-cp2101_2.6.16-r6.4_ixp4xxbe.ipk
I haven't had time to try 3.10 yet, so any feedback would be appreciated.

Cheers

Jon

Installed cleanly and so far looks to be working correctly!!!

I'll keep you posted.

Many Thanks

I'm trying to setup an NSLU2 as well. I've installed the 3.1 binary... everything seems fine, *except* communication with the Vantage Pro. The OS doesn't seem to be noticing it, the cp2101 driver complains about the kernel version, as noted above, but installing the updated package for 2.6.16 doesn't seem to make any difference.

Perhaps I'm not installing the updated package correctly?

I just did:

ipkg install kernel-module-cp2101_2.6.16-r6.4_ixp4xxbe.ipk

and then continued normally in the user guide.

any help greatly appreciated.

edit: just to be clear... I'm using the Davis supplied USB connector to connect directly to the NSLU2... no extensions or anything else abnormal on the physical end.

OpenSlug is installed on a flash drive... in USB Port 2.

Vantage Pro is plugged into USB Port 1.

Hi Chris

I haven't been able to reproduce this, but that could be because I don't have a VP plugged in. Could you do an lsmod to see what's loaded? If cp2101 is there, I'd try unplugging the VP, rmmod the cp2101, ipkg remove kernel-module-cp2101, then re-installing it.

hmmm it doesn't seem to be recognizing the cp2101 module. only usbserial was listed in lsmod aside from the other regular stuff.

I'll try reinstalling it a few times...

Hi again John..

ok this has got to be user error on my part...

when wview.conf is included in the /etc/ipkg configs... it runs off to wviewweather and downloads/tries to install the older package (and thus complains of old kernels and doesn't actually install successfully).

when I remove wview.conf from the ipkg configs it no longer looks for wview stuff... but it also doesn't recognize the module:

I just came back to this forum today to report that the module has been working flawlesly for several weeks .........

The way I installed the module was to place it in a temp directory and use the 'file' mode of ipkg

Suggest being very particular ...
Unplug the VP
reboot
install
reboot
plug in the VP

If all is well - you should see /dev/ttyUSB0

and to install it in "file" mode you simply do:

#: ipkg install kernel-module-cp2101_2.6.16-r6.4_ixp4xxbe.ipk

(i just downloaded the ipk file to my home directory)

thanks I'll keep at it.

ok.. progress... sort of...

i have convince the ipkg to install.

it install the cp2101 and usbserial module in

/lib/modules/2.6.16/kernel/drivers/usb/serial/

however... the OS refuses to load the cp2101 module even though it loads usbserial OK.

lsmod reports usbserial... if I rmmod usbserial... it removes fine...

if I "insmod /lib/modules/2.6.16/kernel/drivers/usb/serial/cp2101"

then it complains:

"-1 Invalid module format"

yet if I "insmod /lib/modules/2.6.16/kernel/drivers/usb/serial/usbserial"

it initialises and shows up in lsmod.

So either there is something wrong with the cp2101 package as I installed it... or the cp2101 file itself is corrupt?

Could we perhaps update the Packages.gz file in the wview ipkg repository so that it includes the new cp2101 file?

Chris

The ipkg only contains one file, cp2101.ko, which is installed to /lib/modules/2.6.16/kernel/drivers/usb/serial/cp2101.ko. As long as this file exists on your system you should be OK to carry on with the next part.

is it because I'm using DebianSlug and not Unslung?

Ah, so trying to shoehorn a big-endian module into a little-endian kernel doesn't work too well? Smile

I've been working on getting the packages rebuilt under 3.10 but for some reason gd won't build under my cross-development system. I keep going back to it and seem to be making progress - hopefully some time this weekend...
