I try to start ex_fb_spectrum example on beagleboard clone with 7" 480x800 LCD and have error in fbdrv//lcd-omap3.c: when a i call any l4vbus_i2c* and l4vbus_gpio function i have return -38 --- ENOSYS error whats may be wrong?
The problem is that 'io' does not currently implement any of the i2c and gpio functionality. There was some experiment some longer time ago from which that code is from.now i am doing some work on touchscreen driver.my board is omap3530,with tcs2046.i see there is l4vbus_mcspi* function,but i cann't find the code for the tcs control device operating.maybe the snapshot doesn't have the "server"?can you offer me some example ,maybe some codes of lcd, i think it's great useful for me.thank you very much! For the beagleboard the LCD is configured by u-boot and can then just be used. Isn't that approach possible with your board?

When the board is in u-boot, is there something displayed on the monitor that is connected to the board? Such as a dog looking like a beagle?
