Hello.
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?
my configs:
--------------------------------------
arm-rv-lcd-io:
gui => new System_bus()
{
# KBD => wrap(hw-root.KBD);
# MOUSE => wrap(hw-root.MOUSE);
}
fbdrv => new System_bus()
{
sys => wrap(hw-root.sys);
lcd => wrap(hw-root.lcd);
i2c1 => wrap(hw-root.i2c1);
gpio => wrap(hw-root.gpio);
}
