Problem about changing LVDS1 to LVDS0 on i.MX6Q SABRE SD platform?

Hi,

I am trying to use LVDS0 channel on SABRE platfrom with linux-3.0.35-4.1.0(u-boot2009),I looked for many issues on this community, such as modifing boot args,or making changes according to  tips in this website https://community.nxp.com/message/363229

but it did not work.

Here is some codes I have changed:

static struct fsl_mxc_ldb_platform_data ldb_data = {
  .ipu_id = 0,
  .disp_id = 0,
  .ext_ref = 1,
  .mode = LDB_SEP0, 
  .sec_ipu_id = 1,
  .sec_disp_id = 1,
};

Are there any other codes need to be modified?

ths.

Hi SUNNY

ldb to ipu mapping is configured in IOMUXC_GPR3 register

LVDSx_MUX_CTL so one can check if this is correct configuration.

Best regards
