Hi everybody, I am very new at Linux and embedded systems. I have ported a 2.6.20 linux kernel with a provided ext2 file system (uClibc 0.9.28 and Busybox v1.1.2) to the board AT91RM9200-EK.
I want to add a wireless extension to the system with an USB Wi-Fi device based on the chipset zd1211. For this purpose, I enabled all the following options in the kernel confiduration as modules: IEEE 802.11, radio, zd1211 drivers etc. When I used the modules commands of my Busybox installed version I had problems loading these modules (I included all .ko files in the file system after compiling) . Then I decided to download a new version of Busybox and compile it with the appropiate configuration for the modules tools. However, the new compiled version didn't work and my file system couldn't be booted. Finally, I have enabled all these options not as modules, but built in the kernel itself. Then I would like to ask if there is something else necessary to do for loading the driver of this device successfully or if it is already done following this procedure. What disadvantages does this procedure of loading drivers in the kernel have? Will I find any problem later? when I recompile the kernel with all modules built inside and I connect the USB device to my target, I obtain the following error: [root@(none) /]# usb 1-1: new full speed USB device using at91_ohci and address 2 usb 1-1: configuration #1 chosen from 1 choice usb 1-1: Could not load firmware file zd1211/zd1211b_ub.
