We have a custom board using a T4240. CodeWarrior is giving us the error message "JTAG chain does not contain any debuggable cores" when we attempt JTAG communication. Not sure if it is in any way related but we also noticed the JTAG IDCODE is 0x1022001D. The documentation says the ID should be 0x0022001D, and that upper 1 is reserved.
Additional information on what might cause either of these two problems or any recommendations one what to focus would be appreciated.
