HOTPLUG.LOG

Busybox 1.19.2
Architecture ARM 920T cpu (s3c2440) - mini2440

Kernel 2.6.32.2 (sources provided by arm9.net)

Kernel cross compiled with arm-gcc 4.3.2 (sources provided by arm9.net)
(arm-none-linux-gnueabi-gcc (Sourcery G++ Lite 2008q3-72) 4.3.2)

Busybox cross compiled by buildroot 2011.08 (arm-gcc 4.6.1, uclibc 0.9.32)

I've find a lot of forum that discuss about this problem,
but I not find a solution for this system!

in /lib/ I have
firmware/rt2870.bin
hotplug/firmware/rt2870.bin

and I also try to
echo "/sbin/mdev" > /proc/sys/kernel/hotplug


Thanks in advance!

/* For the full gory details, see linux/Documentation/firmware_class/README

 * Firmware loading works like this:
 * - kernel sets FIRMWARE env var
 * - userspace checks /lib/firmware/$FIRMWARE
 * - userspace waits for /sys/$DEVPATH/loading to appear
 * - userspace writes "1" to /sys/$DEVPATH/loading
 * - userspace copies /lib/firmware/$FIRMWARE into /sys/$DEVPATH/data
 * - userspace writes "0" (worked) or "-1" (failed) to /sys/$DEVPATH/loading
 * - kernel loads firmware into device
