Week 2 Progress:
-
What has been accomplished?:
- Comparison between NVIDIA Tegra, Freescale iMx and TI Omap MMC driver stack for linux kernel.
- Identified limitation of OMAP TI MMC Hardware which makes it difficult for SDHCI compliance.
- Identified modifications in present Omap MMC driver stack to make it work with kernel sdhci stack.
-
Issues:
- Clocks and register memory mapping of OMAP does not simply match to those of SDHCI. Many tweaks would be needed.
-
Plans for the next period (this is a list of tasks for the author):
-
Get a minimal SDHCI enabled OMAP MMC driver working.
P.S. - The comparison and differences is yet to be updated on the project page-
https://github.com/disdi/MMC-DMA-Linux-performance/wiki/Week2—GSOC-2014
as some more time is requested to allow me to conclude my study.
I would be updating it by tomorrow.
