Hello everybody
I have embedded system based on sh4-cpu with kernel 2.6.17.14. I have
build latest rt73.ko module which is usb-wifi driver. This driver also
need firmware to be loaded into device during initialization.
Basing on information that I found, i put following script in /sbin/hotplug:
#cat /sbin/hotplug
#!/bin/sh
echo hotplug script is runned !
HOTPLUG_FW_DIR=/lib/firmware/
echo 1 > /sys/$DEVPATH/loading
cat $HOTPLUG_FW_DIR/$FIRMWARE > /sysfs/$DEVPATH/data
echo 0 > /sys/$DEVPATH/loading
this file has following flags;
# ls -l /sbin/hotplug
-rwxrwxrwx 1 502 502 1006 Oct 8 2008 /sbin/hotplug
sysfs looks to be correctly configured for this script:
# cat /sys/kernel/uevent_helper
/sbin/hotplug
#
As I supposed when i'm inserting any usb device, I should see "hotplug
script is runned !" message, but there is no message.
After inserting usb-wifi module i see only this:
# rt73: Failed to request_firmware. Check your firmware file location
rt73: Failed to load Firmware.
Firmware is located in:
# ls -l /lib/firmware/
-rwxr--r-- 1 501 501 2048 Oct 6 2008 rt73.bin
as expected in my /sbin/hotplug script.
after inserting regular usb-flash-disk device i see only this:
# sdb: assuming drive cache: write through
sdb: assuming drive cache: write through
I suppose that if /sys/kernel/uevent_helper exists then kernel is
correctly configured for supporting hotplug.
Why my /sbin/hotplug is not running ?
Where I may make mistake ?
Thanks for any help !
