Hi folks
I never done anything with a kernel before, im used to using the cli and getting in there and getting stuff done but thus far i have yet to attempt anything that incurs editing the kernel or kernel config recompiling kernel.

I have mandriva 2010 installed all up-to-date using the 2.6.31.6-desktop586-1mnb
My problem is i have purchased a artec t1 dvb-t usb box which i thought was supported "out the box" how wrong was i, turns out after further investigating the box has a dibcom 3000-m b122a dvb chip, panasonic tuner & cypress chip
when i plug it in it loads the usbtest module, using lsusb the box is identified as

ID 0547:2235 Anchor Chips, Inc. AN2235 EZUSB-FX Microcontroller,

which further reading at linuxtv tells me its

"broken devices where sold with cold id: 0547:2235 . You will need to enable CONFIG_DVB_USB_DIBUSB_MB_FAULTY in the kernel .config to catch those".http://www.linuxtv.org/wiki/index.php/Artec

so now I not sure which firmware it needs although it needs either one of two that I can see, going by the panasonic tuner it uses dvb-usb-dibusb-6.0.0.8.fw or if its not that one and it is defo the broken ones it is this firmware dvb-usb-dibusb-an2235-01.fw

But i have no clue how to go about doing the kernel edit and keeping all my current settings as well with just those two changes, I dont suppose it is as simple as going into kernel.config and editing? lol no I didn't think so, i do look at the file and saw the bits i need to edit but as it says in the file "DO NOT EDIT"

Can some kind soul talk me through it please? Ive read up a lot on doing it but as this is my first ever time and i couldnt find anything directly specific to what i needed to do i sooner have someone guide for my first time please please go on you know you wanna help me out here its xmas its the season to be joyful, no offence to anyone that does not celebrate xmas.

Cheers folks, am keeping my fingers crossed ta

Richy

EDIT- forgot to mention i aslo tried blacklisting usbtest but still loads

Easiest way is do something like this for your kernel:

cat config-2.6.18-164.6.1.el5.centos.plusxen | grep -i faulty
CONFIG_MD_FAULTY=m
CONFIG_DVB_USB_DIBUSB_MB_FAULTY=y

as you can see my kernel on CentOS has this already enabled, so do the same for your running kernel with this:

cat /boot/config-`uname -r` | grep -i faulty

or specify the full name if you don't want to use the uname -r command to auto-detect it from your running kernel (like in my first example - just replace with your kernel config filename).

If you don't have it in your kernel, then you'll need to compile your own kernel unless there is another Mandy kernel out there with this enabled in it.

[tux99]

I just checked, unfortunately CONFIG_DVB_USB_DIBUSB_MB_FAULTY is not set, at least not with the 2.6.31.5-desktop586-1mnb kernel of Mandriva 2010.0.

You will have to build a customized kernel or ask Mandriva to enable this kernel feature in the next update.

[David Batson]

It might be set in one of the other kernels if you want to try them. Maybe kernel-linus, kernel-tmb, or kernel-server.

[ianw1974]

I checked my Mandy box, and I reckon one of these will do the trick:

[root@esprit ian]# urpmf --name kernel | sort | grep -i dvb
v4l-dvb-testing-kernel-2.6.31.5-desktop-0.rc1.1mnb
v4l-dvb-testing-kernel-2.6.31.5-desktop-1mnb
v4l-dvb-testing-kernel-2.6.31.5-server-0.rc1.1mnb
v4l-dvb-testing-kernel-2.6.31.5-server-1mnb
v4l-dvb-testing-kernel-desktop-latest
v4l-dvb-testing-kernel-server-latest

install one of these, I expect it'll have the relative option enabled - probably a better bet than any other considering it directly relates to v4l and dvb.

Install from GUI, or do this from console:

urpmi v4l-dvb-testing-kernel-desktop-latest

[churchnill]

Thanks for the replies folks,
I did check the kernel config yesterday and it is not set but ran the code just to be sure

cat /boot/config-`uname -r` | grep -i faulty
# CONFIG_DVB_USB_DIBUSB_MB_FAULTY is not set

That is using the kernel

uname -r
2.6.31.6-desktop586-1mnb

tux99, that is something i would love to have a go at is build a customized kernel, but alas i am not brave enough to try that one out not unless i got someone to walk me through it, i wouldn't mind if i had a spare box that i could try on my own so it wouldn't matter if i cocked up but both boxes have a lot of data i can ill afford to lose, not that i expect i would lose any data as i am all backed up to another external hard drive.

I think for the moment i best try ianw1974 & david's option of trying a different kernel, downloading the latest v4l dvb testing kernel desktop latest, will let ya all know how it goes later today.

Although im still open to do a kernel recompile or what ever needs to be done to change the option in the kernel im using if its at all possible even and if someone could either point me in the right direction of a howto or any one willing to write up a howto specfic for a mandriva install? Just a thought, trying to expand myself, but never really found any howto's on kernels & config, compiling,recompiling etc etc that i could find easy & straight forward to follow or there are always differences between the one im following and what is actually reflected on the system im using.

Anyways im home & free in a couple of hours so will get cracking with downloading the latest as described in ianw1974 post.

Cheers folks will keep ya updated on how it goes

Richard-

[ianw1974]

I wrote a kernel compile tips and tricks a while back. Only problem was that certain things didn't work, because Mandriva tends to patch the kernel heavily with specific stuff they require and a vanilla kernel from kernel.org doesn't have these patches.

Whilst generally it works OK, some things don't as listed in my tips and tricks for this from people who tried it too. Whilst it's OK, I generally recommend sticking with the ones available via urpmi and the Mandy pre-compiled ones, as mentioned in my post above. Providing you have all your urpmi sources set to download from the internet, you'll be able to download and install using the command I gave in my previous post. Then on reboot, using this kernel, you can check if it has that option in it, and if so, you're all set to go and I hope everything works :)/>

[churchnill]

Well what a bag of worms this has thrown up :-)

OK, ran urpmi v4l-dvb-testing-kernel-desktop-latest and all went ok, rebooted to new kernel, one warning on reboot in to new kernel regarding nvidia drivers but thats not relevant but apart from that it rebooted into the new kernel with the green light on the usb box lit up, all excited i first done a lsusb to check

ID 10b8:0bb9 DiBcom DiBcom USB DVB-T reference design (MOD300) (warm)

Which i didn't think to much about as i knew this box was a problematic with its Id's according to linuxtv so i thought have a look at what driver it loaded up with lshw

usb
description: Generic USB device
product: MOD3000 BOX
vendor: DiBcom SA
physical id: 1
bus info: usb@2:1
version: 0.01
capabilities: usb-1.00
configuration: driver=dvb_usb_dibusb_mb maxpower=500mA speed=12.0MB/s

So i thought all looks good except it was not the module i was expecting to see, i as expecting to see one of either of these

dvb-usb-dibusb-6.0.0.8.fw
dvb-usb-dibusb-an2235-01.fw

So next up is to run w_scan, which runs with no errors but on the same token it doesn't lock onto any channels, tried kaffeine scan and the snr meter doesn't move & signal strength doesn't move.
I must point out i also have another usb stick dvb-t that i use, i took the aerial lead from back of that and put into usb box so i know there is not a issue with any cables or connections as they already work with other usb stick. But i am trying to get another dvb-t tuner on here so i can record & watch different channels.

Back to the kernel then, i assumed this kernel had faulty enabled but alas not

richard]# cat /boot/config-`uname -r` | grep -i faulty
# CONFIG_MD_FAULTY is not set
# CONFIG_DVB_USB_DIBUSB_MB_FAULTY is not set

but then has it loaded the right kernel? i expected it to be named v4l-dvb-testing-kernel-desktop-latest

$ uname -r
2.6.31.5-desktop-1mnb

Anyways its one step closer than it was yesterday, so still hope yet. Any ideas anyone? Start a new thread? I'm off to do some searching & researching, in the mean time if anyone has the answer please do tell :-)

Cheers folks
Richard

[ianw1974]

Are you completely sure you booted the right kernel?

[tux99]

at the grub boot screen try selecting the dvb kernel explicitly, it should be listed as the last option on the bottom.

[churchnill]

I just went into the grub menu to have a look & there is no v4l-dvb kernel mentioned at all, although i did download and install from command line with urpmi v4l-dvb-testing-kernel-desktop-latest & on reboot its picked up the box although the box does not scan correctly it is lighting up, so firmware is being loaded. this is strange is it not?
No mention of the v4l-dvb-testing-kernel-desktop-latest in the grub, but that don't explain how the box now lights up? It also told me there where no proprietary drivers for my nvidia card on reboot which also indicated that i had booted into the new kernel, but alas no mention of the new kernel with

uname -r
2.6.31.6-desktop-1mnb

There is also no mention in the grub menu.

Im more confused now than when i started, what with the usb box being a dodgy one with its id's but alas it would seem people have got it running so will do some research this evening, couldn't get any done yesterday in the end & now with this mystery with the kernel.

After rebooting, i tried several kernels that are installed and box not lighting up no more, that v4l-dvb- kernel seems to gone walk abouts

So i thought all looks good except it was not the module i was expecting to see, i as expecting to see one of either of these

dvb-usb-dibusb-6.0.0.8.fw
dvb-usb-dibusb-an2235-01.fw

Hi, these 2 files aren't modules they're firmwares and they're in the dvb-firmware-usb package in the PLF Non-free repository. You'll need these as well as any required kernel modules. Hope that helps :)/>

Hi cheers for the reply
Yeah i did realise they where firmware but i get my wordings mixed, knew i done it just couldn't be bothered to change it as i thought everyone would know what i meant lol sorry for my laziness :-) sometimes call the firmware drivers as well, i am easily confused, its because i am a blonde and that's my excuse.

Yup i got the plf repository and also have both those two firmwares in lib/firmware, also have dvb-firmware-usb installed, but alas still no joy, what is bugging me is the fact after i installed the v4l-dvb-testing-kernel-desktop-latest and rebooted the usb box was picked up & green light came on, so firmware was loaded but didn't scan correctly, but since shutting down and rebooting today it is not being detected again and has gone back to the old ID's etc in my original post, its not making a lot of sense, well to me at least :-)
