My previous post showed how to use small TFT LCDs as a Linux framebuffer on a BeagleBone Black:   BeagleBone Black LCDs with Prebuilt FBTFT drivers   I showed how to use pre-built fbtft kernel modules to provide the necessary Linux device driver.  However, what if you want to use fbtft modules with a newer version of the Linux kernel?   The BeagleBone Black currently ships with a Linux 3.8 kernel built from Robert C. Nelson's am33x-v3.8 branch.  I do also have fbtft wo ...
