BBB Booting using GPMC Interface and Resetting eMMC lines


I have heard in lot of community blogs and posts that in order to boot BBB using GPMC interface, reset the eMMC and then use GPMC Interface.

Can some on tell me :-

  1. How to do it using bare metal programming such as starterware? Can there be some conceptual help in this?

  2. What will be the sysboot configuration? How will I access eMMC interface for resetting when the boot configuration will be using XIP?

I do not want to remove on board eMMC as this is a very small experiment for us.

Please help.


This does not make sense for me - do you have a link to such a blog post to let me see the exact text?
