Hi Duane and others,
I finally managed to get this thing working (using Duane's patch
therefore ...thanks). The last piece I was missing was something Arnim
Läuger (urjtag) already told
us that the DAP apparently is added before the jcr. I am attaching an
initial working config but it needs more work and needs Duane's patch,
I updated the git and will continue working from there
until we have something decent. Many thanks to many people! specially
Dirk, Duane and Arnim!
you can git clone git://github.com/keesj/openocd-keesj.git
I tried it and can confirm: It works!
Great!!
Now, before (in parallel?) working on Cortex A8 support Rick mentioned,
we should get recent into svn:
Can we get
https://lists.berlios.de/pipermail/openocd-development/2009-March/004840.html
applied? Kees: Or did you any changes? If yes, could you send an updated
version of Duane's patch?
Ah, I forgot: And can we get the two necessary config files into svn, too?
The two files in attachment are mainly cleaned up versions from Kees,
with omap3530 renamed to simply omap3.
Thanks
Dirk
