Hello. We have this DM814 EVM, on which we have replaced both the LCD and touchscreen. This question is for the touchscreen. I rebuilt the kernel after removing the original touchscreen device and added the STM support on both the MFD (Multi-functional Devices) and the touchscreen. However, the touchscreen does not work. I do not see anything created on the /dev/input (the original image creates the /dev/input/event0)... here we should see the /dev/input/stmpe_ts, but it does not exist. Even if I add it using the mknod command (parameteres?), still it does not work.. when I run ts_test it gives an error message "ts_open: no such file..."
It must be something else that I have to do but I do not know what (I edited the file board_ti814evm.c by replacing the line "QT602..., 0x4A" with "stmpe_ts, 0x82" but still nothing.
Any help will be appreciated...
