Hi,
I am a beginner of Linux and I have a problem while integrating a miniPCI WLAN module with RT2561 chip with a ARM-Linux CPE device. The driver, version RT61 v1.1.0.0, is compiled as a dynamic module and loaded (cat /proc/modules: rt61 350488 0). I can find the PCI device (cat /proc/pci:
PCI devices found:
Bus 0, device 0, function 0:
Class 0000: PCI device 159b:4321 (rev 0).
Bus 0, device 9, function 0:
Class 0000: PCI device 1814:0301 (rev 0).
IRQ 155.
Non-prefetchable 32 bit memory at 0xa0000000 [0xa0007fff].)
But the firmware loading process is failed! The DBG shows "NICLoadFirmware: MCU is not ready".
Does anyone have idea if I made any mistake?

Thanks a lot,

Hi,

You need to install firmware files in /etc/Wireless/RT61STA directory. You can download all .bin files from the drivers site or it may be there in source code itself. Don't forget you need to configure rt61sta.dat file and put in same directory. Here listing from my system:
rt2561.bin rt2561s.bin rt2661.bin rt61sta.dat

Hi,

Thanks for your reply.
Yes, I have these files in the directory. However, it seems the BIN file is not written into the memory correctly. The DBG log is as the following:

Thanks,

BTW, my Linux kernel version is 2.4.19. Is this an issue?

I'm using 2.6.xx version and it is working fine my driver version is 1.1.0.0. Try to write fresh copy of BIN file. According to doc it should work with 2.4.xx kernel too. Did you configued rt61sta.dat file? You must edit this file as binary file and not as a text file. I've noticed that correct configuration is required in this file.

Hi,
I have a stupid question. How do you edit a file as binary ?

thanks.

-b is binary mode options, which will be set that makes it possible to edit a binary or executable file.

Thank you. The network interface of ra0 is up now, but the driver can't get any interrupts of tx or rx.
The dump from my console:

It seems the card receives packets, but it drops them for some reason and therefore there's no rx interrupt. How could this happen?
I am using linux 2.4.19 with rt61 driver v1.1.0.0 on ARM platform.

May be you are sharing interrupts see if you can setup something in BIOS

Happen to me also, for my case it because of pci master is failing, hence all packet is dropped. Check the "buffer address" given to the card for pci master access.
