During the board startup, the splash screed did appear; the "ts_test" program or our application were not able to start. The following error message was reported: error: failed to map framebuffer device to memory. LinuxFB: driver cannot connect The issue was discovered, on the LPC32xx platform, during the migration of the LCD definition from the board file to the device tree.
