Keil and Secondary JTAG Problems (LPC2106)

2006-03-21 by Richard

I am using the secondary JTAG interface of the 2106 in a design.  I am
using the Keil tools (uVision and Ulink).  When connecting via the
Ulink I get an error, "Couldn't stop ARM Device!"  
I notice that if I disable either the PLL or MAM then the problem goes
away.
I am running a 14.7456 Mhz xtal with Pll settings such that I get a
CCLK of 58.9824 Mhz.
I have experimented with different MAMTIM values to no avail.

Perhaps I could add a long delay at startup before the PLL is enabled,
right now it is enabled in startup.s.
