As soon as the Pi is booted up, the display takes on a white colour. After starting the driver from the command line, nothing changes.
pi@raspberrypi:~/fbcp-ili9341/build $ sudo ./fbcp-ili9341 bcm_host_get_peripheral_address: 0x20000000, bcm_host_get_peripheral_size: 33554432, bcm_host_get_sdram_address: 0x40000000 BCM core speed: current: 250000000hz, max turbo: 250000000hz.

Source GPU display is 640x480. Output SPI display is 320x240 with a drawable area of 320x240. Applying scaling factor horiz=0.50x & vert=0.50x, xOffset: 0, yOffset: 0, scaledWidth: 320, scaledHeight: 240 Creating dispmanX resource of size 320x240 (aspect ratio=1.333333). GPU grab rectangle is offset x=0,y=0, size w=320xh=240, aspect ratio=1.333333 All initialized, now running main loop...
Above is the command output that I get when starting the driver.
Here's my CMake command line
cmake -DSPI_BUS_CLOCK_DIVISOR=6 -DADAFRUIT_ILI9341_PITFT=ON -DSINGLE_CORE_BOARD=ON ..
