In the directions for generating the firmware file I did not understand this: "set Config_Fresh to 1 and generate the binary config firmware image" Where is Config_Fresh set? Do I set it to 1 at the top of the shell script?... https://github.com/blocksonic/gt9xx/blob/device-tree/goodix-generate-fw.sh Also, your comment was not clear to me... "You might need to revert the patch that enables reset for the Chuwi tablet [3]" Under what conditions do I need to move these changes? The user is reporting the following dmesg output with your latest code... [ 8.635097] goodix_backport: loading out-of-tree module taints kernel.
