Re: [uClinux-dev] Get RT73 driver to work on 2.4 or try to move to 2.6? ARM7 from Nuvoton
Jivin Sima Baymani lays it down ... Hi all, I've been lurking a bit on this list since I got a uClinux project in my lap this summer. I've fiddled a bit with Linux, but this is my first uClinux project and I've not worked this deep with linux drivers before even though I'm familiar with working low level. And now to the question! I know this is ancient 2.4, but this is what I have to work with. I don't expect answers but am grateful for any advice or thoughts you might have. Platform: ARM7 from Nuvoton, more precisely called NUC745. uClinux version: 2.4.20 The product is a webcam with ethernet and wifi, a clone of one of the FOSCAM cameras, produced by Apexis. I need to do a lot of changes in the software and the programs on it. They will not share their source code even though I _know_ they have used uClinux and other open source software under GPL. I got the uClinux-source from a BSP somewhere else. The BSP source runs fine with ethernet working. My problem is that I need wifi to work as well. The driver I have is the RT73 driver from Ralink. Apexis use the same driver but I don't know how much they had to change it to work. I have managed to add the driver to the kernel build and it seems to be loaded (full logs at end of email): usb.c: registered new driver hub add a static ohci host controller device : USB OHCI at membase 0xfff05000, IRQ 15 hc_alloc_ohci usb-ohci.c: AMD756 erratum 4 workaround hc_reset usb.c: new USB bus registered, assigned bus number 1 Product: USB OHCI Root Hub SerialNumber: fff05000 hub.c: USB hub found hub.c: 2 ports detected -RT73-7usb_rtusb_init-- //usb_rtusb_init is the module_init function though this is a compiled in driver SIMA in da house! usb.c: registered new driver rt73 This only tells you the driver was registered. There doesn't seem to be any device detected that matches the rt73 driver. SIMA - Registered RT73 driver! Usb device driver by ns24 zswan designed successfully! Initializing USB Mass Storage driver... usb.c: registered new driver usb-storage USB Mass Storage support registered. But when I get to the prompt neither ifconfig nor iwconfig list any wireless interfaces. If I compare to the original boot log, it looks like hub.c does a bit of probing that my log doesn't have: hub.c: connect-debounce failed, port 1 disabled new USB device :80fc8004-fed640 hub.c: new USB device 1, assigned address 2 probing sonix288 usb camera ... dvm camera registered as video0 new USB device :80fc8604-fed640 hub.c: new USB device 2, assigned address 3 idVendor = 0x148f, idProduct = 0x2573 trying to set up the wireless interfaces gives me this: / ifconfig rausb0 inet 192.168.5.135 up How long after boot ? Sometimes it takes a while for the usb devices to appear, but if you waited at least 15-20 seconds, it isn't going to show :-) You need to get lsusb or look at the appropriate /proc files and see if the wireless USB is actually appearing. Cheers, Davidm SIOCSIFADDR: No such device
