porting to ARM Linux, ifconfig then kernel panic..

I got 2 problems..

1. kernel panic

2. adapter seems shutdown (the power indication led die) when trying to reach dhcp, or setting ip by ifconfig

appreciate for any suggestion !!

============

driver version : rt73-cvs-2008042100

kernel version : 2.6.25

hardware : arm9 s3c2440

usb adapter : ASUS WL-167G

============

scanning ap on my host pc, (it works fine here)

[host] # iwlist wlan0 scanning

Code:

============

I'm using busybox , and mdev instead of udev on target board

Code:

/bin/echo /sbin/mdev > /proc/sys/kernel/hotplug

plug the adapter into usb port

Code:

setting iwconfig

Code:

iwconfig wlan0 ap 00:E0:98:4E:8D:5E
iwconfig wlan0 mode managed
iwconfig wlan0 channel 11
iwconfig wlan0 key off
iwconfig wlan0 rate 11M

getting ip from dhcp

[busybox] # udhcpc -i wlan0

Code:

Sending discover , then the power indication LED on adapter die...

Hello,

could you explain me how you compile the sources with you ARM CrossCompiler ?

In the kernel 2.6.25 there is already a rt73 driver... ?

I am using mdev too, if I try to load the firmware rt73.bin -> an error occurs:
failed to request firmware.... ?

I put the file in my RFS in /lib/firmware

What´s wrong ?

Thank you very very much for help

Best regards

Hi andrewtw,

Looks like you may have stumbled into the hosed recovery logic. The attached patch is *not* a fix, but may head off the panic long enough to allow a reasonably good debug log to be generated. Could you apply it, build with debug enabled, run with "debug=15" as a modprobe parameter, and attach a gzipped copy of /var/log/debug to a posting here?

Thanks,

HI ManuelSahm,

first, you have to prepare arm-linux-toolchain

then, build kernel for arm in your host machine.

as rt73, simply modify rt73/Module/Makefile

for example, add following codes

Code:

ARCH=arm

CROSS_COMPILE=/usr/local/arm/3.4.1/bin/arm-linux-

KERNDIR=/home2/andrew/kernel/linux-2.6.24_config_arm

ROOTFS = /home2/andrew/busybox/rootfs

and modify this

Code:

FIRM_DIR := $(ROOTFS)/lib/firmware

KERNDIR : the official kernel source, config for arm

ROOTFS : the root filesystem location of the embedded linux

/lib/modules/2.6.24.3 : modules of arm linux will be here..

(rt73/Module) # make armdebug ==>comes rt73.ko

(rt73/Module) # file ./rt73.ko

Code:

./rt73.ko: ELF 32-bit LSB relocatable, ARM, version 1, not stripped

(rt73/Module) # sudo make install

Code:

*** Install module in /lib/modules/2.6.24.3/extra

....

*** Install firmware in /home2/andrew/busybox/rootfs/lib/firmware

Hello,

thank you very much.

Which files should be in my embedded linux RootFileSystem ?

rt73.bin : /$(ROOTFS)/lib/firmware
rt73usb.ko : /$(ROOTFS)/lib/modules/2.6.25/extra

Only this two files ?

Do I need mor files in my RFS ? maybe in /etc ?, or somewhere else ?

As described in the post above I added this lines at the top of the Makefile:

Code:

ARCH=arm

CROSS_COMPILE=/opt/elinos-4.2/cdk/arm/v4le/glibc-2.3.4/bin/arm_v4le-

KERNDIR=/root/LRU3000/FEIGKernel/linux-2.6.25

ROOTFS = /exports

and modified the line:

Code:

FIRM_DIR := $(ROOTFS)/lib/firmware

(rt73/Module) # make armdebug -> doesn´t work !!

I have to type: (rt73/Module) # make ARCH=arm CROSS_COMPILE=/opt/elinos-4.2/cdk/arm/v4le/glibc-2.3.4/bin/arm_v4le- armdebug

When I type : (rt73/Module) # sudo make install

Only the firmware file rt73.bin is copied to my embedded linux rfs... not the rt73usb.ko which was built ?

Thank you for your help

Hi Vern :

Sorry for my poor English, I don't know the meaning of "hosed recovery logic".

And, don't know why my debugfs seems not work, even if I check the rt73 debug module in 'make menuconfig' .

So I paste the dmesg log below.

And I found the adapter die because of setting ip by 'ifconfig wlan0 xxx.xxx.xxx.xxx'

Any action related with ifconfig ifconfig will cause my adapter die.

Only the firmware file rt73.bin is copied to my embedded linux rfs... not the rt73usb.ko which was built ?

Thank you for your help

Hi ManuelSahm :

I do copy only these two files to the embedded rootfs.
rt73.ko @ ($ROOTFS)/lib/modules/<kernel version>/extra/
rt73.bin @ ($ROOTFS)/lib/firmware

Actually, I'm not so sure if there're any other file need by this driver...

I found there's rt73sta.dat in Ralink official driver, need to be placed at /etc/Wireless/TR73STA

Maybe the rt73sta.dat is discard in this project......?

Hello andrewtw and all others,

I´m not able to load the firmware rt73.bin...(placed in /lib/firmware)

I´m using mdev with busybox 1.9.1 and kernel 2.6.25...

Could you send me your busybox config and kernel config ?

I don´t know what could be the problem...andy ideas ?

Thank you

Guys:

Please, one thread, one topic.

ManuelSahm: Please start another thread with your question.

andrewtw:

When you have non-trivial amounts of supporting data, please attach it as one or more gzipped files to your post. Otherwise it makes it hard to pick out the sense of what you're saying.

To say something is "hosed" is a slang expression meaning it doesn't work.

What I'm asking for is unrelated to debugfs. Rather, I'm asking to compile with debug enabled ("make clean debug"), followed with a "make modules_install" or "make install" (as root). See the README and TESTING files for more information.

Add "debug=15" as a parameter to modprobe, then do the procedure that causes the problem. Gzip a copy of /var/log/debug and attach it to a post to this thread.

Thanks,

Hi Vern

sorry for my stupid

the log deamon in my embedded busybox seems not work well... something wrong with log alignment

it took me some time to deal with it.. but there're still a problem, so I handly copy/paste the lost message from dmesg to missed_message

version : rt73-cvs-2008042907

# ifconfig wlan0 down

# modprbe rt73 debug=15 firmName=/lib/firmware/rt73.bin

# ifconfig wlan0 up // error occur from here..?

starts from line 12 in message.tar.gz, plz refer to missed_message

Hi andrewtw,

I see you're using 2.6.25, which has the nextgen drivers. So there's a possibility that we're having a collision here. To find out, you can go to your kernel source directory and do

Code:

egrep 'CONFIG_RT[267]' .config

If any of those are set to "y", or "m", then you have the nextgen driver(s) enabled in addition to the legacy driver (not good).

If you wish to use the legacy driver, you need to make sure that the nextgen driver is not compiled into the kernel or compiled as a module.

If you wish to use the nextgen driver, then make sure that the rt73.ko module is not in /lib/modules/`uname -r`/extra, and that there is no alias for wlan* to rt73 in /etc/modprobe.d/ralink.

Please post the results of this effort here before we proceed further,

Thanks,

Hi adrewtw,

OK. Doesn't look like there's any driver collision. Did you apply the patch I uploaded?

I notice in an earlier post you did

Quote:

# modprbe rt73 debug=15 firmName=/lib/firmware/rt73.bin

(I assume we have a little typo, here.) Even though the driver doesn't complain about the firmName parameter, it won't work either. For now, please make sure you have the firmware file (rt73.bin) in /lib/firmware, and don't use the firmName parameter.

Your log files are still partially corrupt. Please fix that first. I say this because whatever's causing that can also be causing other problems.

Thanks,
