启动 log 是这样的:
[ 1.104468] i2c /dev entries driver
[ 1.228881] Goodix-TS 0-0014: ID 911, version: 1060
[ 1.234417] Goodix-TS 0-0014: Direct firmware load for goodix_911_cfg.bin failed with error -2
我的显示屏分辨率是 1024*600,
所以我想把触摸长宽也跳到这个分辨率.
据说是要在文件系统建立 /lib/firmware/goodix_911_cfg.bin, 驱动启动的时候加载这个触摸固件,
但是网上无论如何都没有搜索到这个固件,
这个是厂家提供的吗?我应该找谁要?

On the host:
- modify some fields from goodix_911_cfg (e.g. change resolution of
x/y axes, maximum reported touch points, switch X,Y axes). For more
details check datasheet for format of Configuration Registers.
- run tools/touch-goodix-generate-fw.sh on the modified script to
obtain a valid config (it needs to recompute the checksum, set
Config_Fresh to 1 and generate the binary config firmware image):
$ ./tools/touch-goodix-generate-fw.sh goodix_911_cfg
- copy goodix_911_cfg.bin on the target in /lib/firmware
- when the goodix driver is initialized it will read the new config
firmware from /lib/firmware/goodix_911_cfg.bin and write it to the
device
- check that the new firmware was actually written to the device by
reading the config again on the target from
/sys/class/input/input4/device/dump_config. Also check that Config_Fresh
has been reset to 0. You can also check if the functionality changed
in the config has actually changed (reported resolution for x/y has
changed, x,y axis are switched, etc.)

加载固件是通用的做法，还有种简单的方法是买汇顶的产测工具，直接固化参数，不用加载固件了
请问哪里下载固件，哪里下载量产工具呢?

要淘宝上的买啊，有了产测工具，你想用固件就用固件，想固化就固化
你的淘宝店有吗?

没得，直接上淘宝搜汇顶产测工具
谢谢，我这就去淘宝搜搜
