kernel module cannot find firmware file on Android device; where should it be?

Question

I am having trouble placing firmware properly on an Android device, I keep getting:

<3>[ 3590.997375] usb 3-1.4: ath9k_htc: Firmware - htc_7010.fw not foun         


        

Answer 1

The kernel executes a user-space script to load the firmware. Check if you have the script on the right location.

1. Check the which location the kernel looks for the script. / # cat /proc/sys/kernel/hotplug. The default location is "/sbin/hotplug".
2. Check if you have the script, the kernel is looking for, in this location. On android the script should be "/system/busybox/sbin/mdev", so you can set "/proc/sys/kernel/hotplug" to this, if it is not.
