I think I remember somebody had experimented with OpenOCD, and there was
some problem related to the initial reset of the CPU. Something
regarding the PLL setup, perhaps? But apart from that, it seemed to be
(of course only on those phones that expose JTAG, which specifically is
_not_ the C123 we have seen, but only C115, C117 and C155).
I don't remember who did that, though. Let's hope they still read this
list and respond separately.
We didn't really make use of it as most people have C123, and also we
have not really needed it during our development of the existing code.
