Hello.
I try to extend OMAP4 frame-buffer driver for using with LCD. Your HDMI example does not work. I try to read OMAP DSS registers and receive strange values, for example: value DSS_REVISION is 0x02100004, other DSS and DISPC registers has similar values. What version u-boot do you use on pandaboard? Maybe part of the initialization is performed in u-boot.
Yes that could be the case. We use the Linaro-version of u-boot (git://git.linaro.org/boot/u-boot-linaro-stable.git) on the 'Linaro-u-boot-2011.12' branch. The behavior you describe though, kind of looks like as if the I/O memory base of the controller might be wrong. What version of the PandaBoard do you use? We only tested the thing on ES.
