我遇到麻烦,要把“公司”安装在“安乐器”上,我经常看到:
<3>[ 3590.997375] usb 3-1.4: ath9k_htc: Firmware - htc_7010.fw not found
如果使用标准班轮机运行Utub,我就座于7010。 f 在校正/打字中,我没有发现这一错误。
然而,如果我把这家企业的信息放在安伯斯,那么我仍然有错误。 我已尝试过以下所有目录,并且仍然有错误:
/lib/firmware
/etc/firmware
/system/lib/modules
/system/lib/firmware
/system/etc
没有任何这样的uck子......公司应当在哪里做什么决定,我如何确定公司在哪些目录上为公司信息扫描?
在Anderson(任何途径)上,它有自己的 da/服务(或你想要称之为它)来管理热电pl事件,包括公司加电要求。 在<android>/system/core/init/devices.c上,有两条<代码>#define ,其中列明将检查公司认识的地点:
#define FIRMWARE_DIR1 "/etc/firmware"
#define FIRMWARE_DIR2 "/vendor/firmware"
On my initial build of the ICS filesystem, /etc/firmware didn t exist (and the etc directory seems to be a symbolic link created at boot/init time). The directory I had to place firmware in on my NFS mounted rootfs was <mount point>/system/etc/firmware
After doing this, request_firmware() calls from my module successfully completed.
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
<android>/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.
The kernel executes a user-space script to load the firmware. Check if you have the script on the right location.
