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. For the beagleboard the LCD is configured by u-boot and can then just be used. Isn't that approach possible with your board?
yep, that's the reason why i dint see any think help full for i2c in io. my uboot don't configure LCD, but i added some some scripts for i2c's led power up: imw 0x4a 0xee 0; imw 0x49 0x9e 0x80
and some dss initialisation in LCD driver, so, now i have worked display. and i have some noises on screen, but i think i will fix it.
