"Providing Direction for your Embedded Linux Projects"
The website has been updated with a bit more content and structure. The site will be kept small and relatively simple by design.
I now have the OMAP3 EVM (TMDSEVM3530) development platform. This is an older TI OMAP platform that still exist in some designs. It's software still receives a level of maintenance in Linux and U-Boot. It give me yet another board on which to tinker
As soon as I started working with the board, a small change was needed to get things to at least boot. It became a interesting point of conversation. [PATCH v2]
Now that U-Boot is booting the OMAP3 EVM consistently, I turned my attention to the Linux Device Tree for the board. There are two variants of the EVM (TMDSEVM3530 and TMDSEVM3730). Aside from the processor modules, they are identical. A few core pad-to-pin mappings are different, with respect to the hardware debug lines. (i.e. omap3_pmx_core2 [etk_XXX]) The existing device tree, for the OMAP3730, has received a good bit of attention over time. The OMAP3530 was left behind. This is an effort to get the two processor modules working on par with each other. [PATCH v2] [PATCH v3]
