Hello, on our imx6 quad based board we are tryng to configure two LVDS displays.
I can correctly bring them on through board file configurations:
static struct ipuv3_fb_platform_data fb_data[] =
{
{
.disp_dev = "ldb",
.interface_pix_fmt = IPU_PIX_FMT_RGB666,
.mode_str = "1024600",
.default_bpp = 16,
.int_clk = false,
.late_init = false,
},
{
.disp_dev = "ldb",
.interface_pix_fmt = IPU_PIX_FMT_RGB24,
.mode_str = "800480",
.default_bpp = 16,
.int_clk = false,
.late_init = false,
},
}
and
static struct fsl_mxc_ldb_platform_data ldb_data = { .ipu_id = 0, .disp_id = 0,
.ext_ref = 1, .mode = LDB_SEP1, .sec_ipu_id = 1, .sec_disp_id = 1, };
My problem is that displays are always set up as fb0 + fb1 and fb2 but i'd like to have overlay on both channels;
from my understanding of ipu I should configure first display as ipu0 - display0 and second as ipu1 - display0 thus obtaininig
fb0 + fb1 and fb3 + fb4. I tried many solutions but nothing seems to work. I suppose i'm missing something.
Can you give me any hint or point me to some documentation explaining in detail mx6 frame buffers configurations?
Thank you!
