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

I had a similar problem with my firmware named : down3.bin
(Beforehand, I had insert my module "io_ti.ko" with # insmod of course)

When I plugged my device (USB-RS232 converter, Digi International EdgeportTI1 port adapter) on my Android tablet (Samsung Galaxy Tab 2), he was unable to find his firmware in "linux android adapted directories". So, like you, I tried to put my "down3.bin" in:

/lib/firmware
/etc/firmware
/system/lib/modules
/system/lib/firmware
/system/etc

with :# dmesg I still had error :

<6>[00000.00000] io_ti 1-1:1.0 : Edgeport TI 1 port adapter converter detected
<6>[00000.00000] Failed to load image "edgeport/down3.bin" err-2
<6>[00000.00000] io_ti:probe of 1-1:1.0 failed with error -5

err -2 = [ENOENT] = No such file or directory.

In fact, like you mentionned :

In /system/core/init/devices.c, there are two #defines that specify locations where firmware will be checked:

#define FIRMWARE_DIR1   "/etc/firmware"
#define FIRMWARE_DIR2   "/vendor/firmware"

- So you have to put your firmware in one of these directories. It worked properly for me, hopefully.
