Other Parts Discussed in Thread: OMAP3530

I have omap3530 based board. I have u-boot with support boot splash logo. But during Linux kernel loading DSS is reinitialized and this resulting in

1) at first, lcd shut down for a few seconds;

2) then penguin logo appears in the left top corner and usual kernel log displays.

How can I disable reinitialization of DSS by Linux, so boot splash remains during Linux kernel loading?

    Hi Konstantin,

    The reinitialization of the DSS by Linux kernel could be skipped but this is complicated task. I suggest you to start by setting the HWMOD_INIT_NO_RESET and HWMOD_CONTROL_OPT_CLKS_IN_RESET hwmod flags in the struct omap_hwmod *oh.

    The suitable place for setting both flags is ./arch/arm/mach-omap2/omap_hwmod.c or ./arch/arm/plat-omap/include/plat/omap_hwmod.h files.
