[U-Boot] ep93xx port status
Hi Matthew I see the ep93xx support in u-boot was added in feb 2010 and removed in aug/sep 2011. I'm looking at fixing and maintaining this for our product - do you remember the status of this port, and to what extent it worked on the EDB93xx boards with what issues?
Thanks

You can dig this from the U-Boot history (hint: git log ; hint #2: gitk).

Hi Martin,
the main issue the ep93xx port had was relocation. I spent some time trying to fix it but got stuck digging in the dark as my boards don't expose the JTAG interface. besides that there where no issues known to me, it was possible to boot from NOR or via tftp and start Linux
I used the port on boards based on the edb9301 and edb9307a designs. People reported having it working on other boards of the edb93xx family, i recall the edb9315a was one of them
I hope this information is useful for you. Although I don't use the platform anymore I would love to see the port resucitate :)
Best regards
Matthias

That's what I'm seeing, having fixed one bug in the initial setup due to the fact that the low level initial setup code runs from flash before relocation and from RAM at a different address after, so nothing can use absolute text addresses at that early stage.

Thanks, that's exactly what I needed to know. I am guessing that it was removed because things had changed in the u-boot infrastructure but this port wasn't updated and didn't compile any more.
