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. Rich
