Hello Nick, the other problem is that Samsung may want you to sign the
NDA and keep quiet about the device, as they did when I asked for some
documentation for one device
Hi everyone,
Using the Bus Pirate's JTAG macros, my S5PC100 returns a valid 3.3V
JTAG chain with 250 devices (it's a highly integrated SoC, so 250
sounds like a plausible number), each with IDCODE = 0: while a
Cortex-M3 microcontroller returns a single-device chain with the
correct id value.

Btw. have you tried UrJTAG and the discovery command - it helps
finding such registers on unknown
Hi everyone,
Ah, I should have added that voltage was the very first thing I
checked. On the S5PC100 the JTAG runs at VDD_EXT which has a valid
operating range from below 1.8V to above 3.3V, and the board I'm
trying to bring up has VDD_EXT set to 3.3V (as designed, measured to
~3.25V), so
I imagine the problem is voltage, actually. The OMAP3530 and other similar
devices run their JTAG ports at 1.8V, and the ARM-USB-OCD doesn't like working
below 3V.

True, and important. Thought I'm not sure
quite what you mean by Similar. Don't
the Sitara chips run at 3V3
