Overview of RMHost

The RMHost controller converts RDI function calls into RealMonitor protocol packets, and uses the chosen JTAG unit to send these over the Debug Communications Channel (DCC) of the ARM processor. Additionally, RMHost uses the signals generated by the JTAG unit to control operation of RMTarget. For these reasons, the software that drives the JTAG unit must comply with RDI 1.5.1rt.

You must configure the RMHost controller when you first request connection to the target, which must already be running. You must then choose the supported JTAG unit to be used to communicate with, and control, the target. For complete details on the procedure for selecting and configuring the RMHost controller, see Procedure for connecting to RMHost using AXD on page 22.
