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
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.
