AdaFruit RA8875 board and TFT only showing white screen #20

Hi,

I have a reclaimed 4.3" TFT, 40 pin model FPC4304009 that I pulled from a MP4 player I got for free a while back. I have not been able to find a datasheet for it, but according to an aliexpress listing for it (http://www.aliexpress.com/item/4-3-4-3inch-TFT-LCD-LCM-Display-PANEL-SCREEN-RGB-480-272-FPC4304005-FPC4304006-FPC4304009/32272567308.html), it runs on the following drivers: HX8257 ILI6480 OTM5180

I have attached it to a AdaFruit RA8875 driver board (http://www.adafruit.com/products/1590) and successfully used their library (https://github.com/adafruit/Adafruit_RA8875) from a duemilanove using the init of RA8875_800x480.

I am now attempting to attach it to an original model RPi with the following wiring:

RA8875 RPi RPi Pin #
VIN 5V 2
GND GND 6
SCK SCLK 23
MISO MISO 21
MOSI MOSI 19
CS SP10 CE0 24
RST GPIO 25 22

Powering the RPi on causes a momentary flicker of the screen, much like when powered by an arduino. Once the RPi has booted, and I run sudo modprobe fbtft_device name=er_tftm070_5, the screen turns on with a solid white background. Any other interaction with the fb device fails.

Here is the output with 'debug=1':

Hopefully @Pfannex still checks these issues as well (thanks for all the work you guys already have done on fbtft and his work on the RA8875 driver - read through the whole history and development of it to see if I could figure anything out on my own - alas I couldn't).

Thanks,

Just for completeness sake, I just received my RPi2 today - i did a fresh install, added the rpi-firmware, and did a similar hookup to the RPi2 - same result. I assume it's an issue with the driver/RA8875 - but I could just be doing something completely wrong.

Thanks again,

Elliott

White display means it's not initialized. The cause of this is usually either wrong wiring or wrong init sequence. (debug=3 is enough to see the init sequence)

Hi, did you find an error, I have the same issue? Also, are you sure about the wiring, especially : CS SP10 CE0 24 (is this SPI_CE0_N - http://www.element14.com/community/servlet/JiveServlet/previewBody/73950-102-4-309126/GPIO_Pi2.png) RST GPIO 25 22 (GPIO_GEN6) Thanks

Hi, I've got the same problem. My 5" LCD display is white. I don't know how to install the driver correctly. I use Adafruit RA8875 driver board, and this LCD: http://www.buydisplay.com/default/5-tft-lcd-display-module-wvga-800x480-high-resolution-for-mp4-gps

My wiring is: RA8875 | RPi Vin -> 5.0V GND -> GND SCK -> GPIO11 (SPI_CLK) MISO -> GPIO9 (SPI_MISO) MOSI -> GPIO10 (SPI_MOSI) CS -> GPIO7 (SPI_CE1_N) RST -> GPIO25

Can any help me?

Thanks
