Hello Dmitry,

No, I don't think so, that this is the case. Because, when I disabled the FW configuration loading device is working as well. To be honest, I don't need a new configuration for each boot 😊.

Regards,
Andrej

Firmware file loadind for GT911 controller takes too much time (~60s).
There is no check that configuration is the same which is already present.
This happens always during boot, which makes touchscreen unusable.

Add there an option to prevent firmware file loading, but keep it
enabled by default.

I thought that Goodix was losing firmware loading at poweroff. Is this not the case with this model?

Adding Hans as he was working with this driver/code.
