Hi!
I'm trying to display an image on TFT lcd with x-loader or even a solid background color.
My problem is that pin DSS_DATA0 thru DSS_DATA5 are always low (tested with scope) so blue colors are not displayed. Red and green works fine.
I have checked initialization in omap3_dss_panel_config, omap3_dss_enable and also the MUX and all seems ok.
Do you have any suggestion?

Regards,
Francesco Lodi

On DM3730 dss_data[0..5] pins are powered via VDDS_SDI power domain, on IGEP boards this domain is supplied by the VPLL2 regulator. You should enable this regulator in bootloader. Hope it helps you.

    Yes thanks. This solved my problem. May be to enable this regulator should become standard in the next xloader version?
