Hi, -I am not able to get the new adafruit 2.2" display to work with my raspberry pi b+ model. -I am running 2014-06-20-wheezy-raspbian-2014-07-25-fbtft-master-firmware.zip. -When i load the drivers using sudo modprobe fbtft_device name=adafruit22 -The screen flashes black and then returns to white. -Connections RST GPIO25 (P1-22) and BL to GPIO23 (P1-16) -Previous connections: BL was wired to GPIO18 (P1-12) as recommended for the new adafruit 2.2", still not luck with the display. always white

-dmesg output fbtft_device: SPI devices registered: fbtft_device: spidev spi0.0 500kHz 8 bits mode=0x00 fbtft_device: spidev spi0.1 500kHz 8 bits mode=0x00 fbtft_device: 'fb' Platform devices registered: fbtft_device: bcm2708_fb id=-1 pdata? no fbtft_device: Deleting spi0.0 fbtft_device: GPIOS used by 'adafruit22': fbtft_device: 'reset' = GPIO25 fbtft_device: 'led' = GPIO23 fbtft_device: SPI devices registered: fbtft_device: spidev spi0.1 500kHz 8 bits mode=0x00 fbtft_device: fb_hx8340bn spi0.0 32000kHz 8 bits mode=0x00 fb_hx8340bn spi0.0: setup: invalid bits_per_word 9 (must be 8) fb_hx8340bn spi0.0: 9-bit SPI not available, emulating using 8-bit. graphics fb1: fb_hx8340bn frame buffer, 176x220, 75 KiB video memory, 16 KiB buffer memory, fps=20, spi0.0 at 32 MHz

-when i try con2fbmap 1 1 the adafruit display remains white. -I have use con2fbmap 1 0 to switch back to HDMI,

This is my first time using an Rpi, Any ideas on what I might be doing wrong?

Thanks for the help

Which Adafruit 2.2" display? The pitft display is called pitft.
