[zd1211-devs] Help with zd1211 firmware
Hi everybody, I am working with and embedded system (AT91RM9200-EK) and I want to add a zd1211 Wi-Fi USB device. I want to avoid loading the driver as a module and then I have built all options regarding to IEEE 802.11, zd1211 driver, and firmware loading in the kernel itself. However, when I plug the device I obtain: [root@(none) /]# usb 1-1: USB disconnect, address 2 usb 1-1: new full speed USB device using at91_ohci and address 3 usb 1-1: configuration #1 chosen from 1 choice usb 1-1: Could not load firmware file zd1211/zd1211b_ub. Error number -2 zd1211rw 1-1:1.0: couldn't load firmware. Error number -2 usb 1-1: reset full speed USB device using at91_ohci and address 3 zd1211rw: probe of 1-1:1.0 failed with error -2 usb 1-1: device_add(1-1:1.0) -- -2 Then I downloaded the zd1211 firmware from sourceforge and I have updated my filesystem with these files in /lib/firmware/zd1211/ But unfortunately, I obtain the same error. Do you know how can I solve this problem? Is there any possibility to point the kernel to these files for including them in the compiled kernel image?

Re: [zd1211-devs] Super huge ping with zd1211rw_mac80211

Well, they were fairly random, i.e. sometimes it worked well, and sometimes look 10 seconds - and then after a few minutes was okay. You'll be pleased to know that with the latest wireless-dev snapshot (and latest linus) everything is going much better. I can't tell you what fixed it, but it now just works. Thanks. Richard. This sounds good. However notice that wireless performance differs a lot depending on the actual interference. In my home it varies a lot, probably caused by WLANs of my neighbours. I have implemented a change for the mac80211-based driver, which should remove one source for higher latency. However I still can observe latencies between 300 and 400 ms once in a while. -- Uli Kunitz - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
