I am having problems to the 2106 using the secondary JTAG, this is on a prototype board. Keil gives me the message: "Couldn't stop the ARM device. Check the JTAG cable" The particulars: Keil IDE DBGSEL is pulled low. RTCK is pulled low TRST, TDI, TDO, and TMS are pulled high TCK is pulled low 14.7456 MHz Xtal I have used this setup in two ther designs without problems. I configure PINSEL2 to 0x55400000 as I always have. I have slow the JTAG as slow as it will go. I can see all the signals active on the logic analyser. Ideas? Thanks Rich
