Hi Dominic!
Haven’t been here in the forums for quite sometime.
Looks really busy!
I noticed in your wiki that you’ve cleaned up a lot
of the Big/Little Endian issues (expect for the flashing part).
I’m about to go back into using OpenOCD with my
ARM processor; now the LPC2364 instead of the LPC2148.
I was wondering if you have heard of anyone using
the Big Endian side of things and if there’s still
some open issues there?
otherwise, I guess I’ll be the guinea pig again! :lol:
cheers!

Hello Luis,
I had a big-endian target (NET+ARM) which worked fine, but big-endian hosts are very rare, so I fear this is still untested. Basically it should work, I’ve reworked all endianess criticial parts in the code that I found.
When using a LPC23xx make sure you initally use a very low JTAG speed, as these uCs come out of reset running from a 4 MHz oscillator and the ARM7TDMI-S must not be run at more than 1/6th of that frequency. The FT2232 (IIRC you were using one?) runs at 6 MHz / (1 + jtag_speed), you should be fine with a value of 9 or 10.
Regards,
Dominic
