OcdLibRemote/OcdCommander and Wiggler on LPC210x

Started by Johan Forrer April 14, 2004
Greetings,

After being around the block a few times with this
sticky issue, thought I'd pass along my findings.

Both OcdCommander and OcdLibRemote works with the
Wiggler hardware on the LPC210x, but you'll need to
disconnect nRST connection for the LPC210x target.

Since nRST behaves differently on my EB40A eval
board(AT91R40008) and I move between these two
platforms, I installed a toggle switch on the Wiggler
box to enable/disable nRST control; Enable nRST for
the Atmel, and disable it for the LPC210x.

There was some discussion of this issue on Usenet ---
not clear what exactly the issue is, evidently there
are subtle differences. Anyhow, as long as it works
and we can have fun now.

Regards,

Johan.

OCDCommander works fine for me with nRST connected to the Wiggler. I
haven't tried OCDLib Remote with it yet.

Actually, I've found just the opposite. I've has to disconnect
nRST when working with Atmel ARMs but have had no problem with
it being connected when working with the LPC.

Mine is OK with the old Atmel EB01 board with nRST connected.
