Using a file system（am335x-evm-linux-rt-06.01.00.08.img.zip） that comes with the PSDK does not have ts_calibrate，I need to rebuild the file system without wayland？

Hello Qing,

I apologize for the delayed response. TI supports resistive touchscreen 1) using weston/wayland, or 2) without weston, but using tslib. The default filesystems in the PSDK use weston.

These posts have more information on using Yocto to rebuild the filesystem without weston/wayland:
Running EGFLS instead of Wayland
