ralink RT5370 WiFi support

[sbp]

Hi Gerrelt and bmarkus

Now I have received my ralink wifi adaptor (the same as Gerrelt) - using the newest version 5 alpha 2.

It is not working out of the box. What I have found out is the following:
1. crc-ccitt.ko is present in picore 5

Code: [Select]

tc@box:/$ sudo find / -name crc-ccitt.ko
/lib/modules/3.10.10-piCore/kernel/lib/crc-ccitt.ko

2. The wifi card is seen by lsusb:

Code: [Select]

tc@box:/$ lsusb

Bus 001 Device 005: ID 03f0:0024 Hewlett-Packard KU-0316 Keyboard

3. The modules are present in picore 5:

Code: [Select]

tc@box:/$ sudo find / -name rt2*

/lib/modules/3.10.10-piCore/kernel/drivers/net/wireless/rt2x00/rt2500usb.ko
The problems:
1. However neither the modules nor crc-ccitt are loaded when the ralink wifi stick is inserted:

Code: [Select]

tc@box:/$ lsmod
Module                  Size  Used by    Not tainted
snd_usb_audio         115452  0

squashfs               25727 25
lzo_decompress          1377  1 squashfs


2. I´m sure that we need to add the firmware.
So would it be possible to make a ralink_firmware.tcz containing this directory structure:
/lib/firmware/rt2870.bin
then mksquashfs it and make a MD5sum file?

Then put these two files in the mmcblk0p2/tce/optional directory?

I will try to compile the drivers as soon as I've got the kernel header files on my TinyCore Raspberry.
If that succeeds, creating a ralink_firmware.tcz sounds like a good idea.

Hi Gerrelt

The following is what I think - so it might be wrong.
What drivers are you missing? As far as I can see all the modules are there. So there is no need to compile anything.
In my understanding of the problem we just need the firmware which can be downloaded from ralink. However, I haven't figured out how to "inject" the firmware into piCore via a tcz package.

Steen

do you have the firmware in any format or a link where to find it?

[sbp]

bmarcus

In this post there is a description of the problem in raspberry and a link to where the firmware can be downloaded:
http://www.raspberrypi.org/phpBB3/viewtopic.php?f=28&t=22623

I have extracted rt2800.bin and you can get it here:

PS: I think that there might be a problem with how piCore 5 handles USB devices compared with 4.7.7.

If booting 4.7.7 with the ralink wifi attached, it finds and loads the correct ralink modules and the crc-ccitt module (just complaining about missing firmware).
If booting 5 with the ralink wifi attached it does not find and boot the ralink modules or the crc-ccitt module.

Yes, there are some issues with USB in 5.0.alpha2 which will be addressed when Xorg and GTK2 ready.

Ralink fw must be managed first in 4.7.7 and moved to 5.0 later.

Ralink fw must be managed first in 4.7.7 and moved to 5.0 later.

I agree, therefore I tried to make a ralink_firmware.tzc and a MD5-checksum file and put it in the TCE/optional directory.  My hope was that the firmware would be loaded during boot.

However, I found no trace of the rt2800.bin file anywhere in piCore 4.7.7 after booting. 

I think the correct place for the firmware should be lib/firmware/rt2800.bin

Sent PM with download link to a tcz package, please try.

Hi bmarkus


It is working - the ralink5370 is now connected.

I needed to do the following steps:
1.Copy your firmware.tzc to TCE/optional (the three files)
2. Then tce-load -i firmware-ralinkwifi
3. Then sudo ifconfig wlan0 down
4  Then sudo ifconfig wlan0 up

AND now it is working.

Thank you....

Can you see how we can automatically load the firmware-ralinkwifi.tcz before the wifi packages are loaded?

Steen

Add it to your onboot.lst.

Hi Steen,

   Apparently I confused "drivers" with "firmware", that shows I'm just a newby when it comes to Linux...

It's great to see you got it working!

Greetings,
   Gerrelt.

[bmarkus]

I will add it to the repo

[bmarkus]

firmware-ralinkwifi.tcz added to piCore 4.x/5.x repo. It is coreplayer2's 5.x x86 extension repacked for piCore

[Gerrelt]

Hi Bmarkus,

Yes!!! Thank you, it's working now.   

I installed the firmware-ralikwifi.tcz, and rebooted. But then it didn't work.
I had to add this to my bootlocal.sh:

Code: [Select]

modprobe rt2800lib
modprobe rt2800usb
(this might not be the best solution?)

After a "filetool.sh -b" and a reboot, it worked.

Greetings,
    Gerrelt.

[bmarkus]

Great! I can add modprobes to the startup script.
