I will be using Lauterbach Trace32 that supports both JTAG and Trace debugging. This debugger uses an ARM MIPI-38 to connect to the trace/JTAG lines or it can use both a MIPI-38 and separate JTAG connector for debugging and tracing.
My question is on the following debug lines:
I am not sure how these should be connected in hardware. The documentation is not clear on what is needed. I see some implementations where JTAG_DE_B is connected to the debugger DBGRQ pin and some were JTAG_DE_B is permanently pulled high. What is the recommended practice?
Also, do ARM_EVENTI and ARM_EVENTO need to be connected? Pulled high, low, left floating?
