mx53_smd VGA Display

if I use the mx53_smd BSP, I can't use VGA Display,

but when I use mx53_loco BSP, it work. Why? There are

some differeces between mx53_smd and mx53_loco?

Thanks!

The LVDS is the default display for the SMD. Have you tried changing the bootargs?
What board are you using? is this a custom board?

Thankyou, in mx53_smd.c files,

change:

static struct tve_platform_data tve_data = {

.dac_reg = "DA9052_LDO7",

};

static struct ldb_platform_data ldb_data = {

.ext_ref = 1,

.boot_enable = MXC_LDBDI1,

};

static struct tve_platform_data tve_data = {

.dac_reg = "DA9052_LDO7",

.boot_enable = MXC_TVE_VGA,//2012-12-28 by add zhoudan

};

static struct ldb_platform_data ldb_data = {

.ext_ref = 1,

//.boot_enable = MXC_LDBDI1,

};

and it work.
