BSP-bugs in pin routing for LCD parallel interface

tomasznowak — Wed, 16 Oct 2013 11:53:12 GMT

Hello,

I'm integrating imx6dl with an LCD (over parallel interface). The problem I encountered were some strange graphical artifacts on the display (blue points etc...).

Further investigation led to concusion that the pad control configuration for some pins of the interface is inproper (should be MX6DL_DISP_PAD_CTL)

Please correct it in the next BSP release.

Affected file: arch/arm/plat-mxc/include/mach/iomux-mx6dl.h

Affected macros: MX6DL_PAD_DISP0_DAT2__IPU1_DISP0_DAT_2 and MX6DL_PAD_DISP0_DAT10__IPU1_DISP0_DAT_10

Best greetings

Tomasz Nowak

We have performed a frammebuffer test and the colors seem to be correct. Besides we can see activity on both nets using a probe. Just in case we're going to modify the macros.

Thanks Tomasz.
