ARM DUI 0137A

37

This section describes all error messages you might receive when connecting to, or 
using, RMHost. 

 Error messages can be generated by both the debugger and the JTAG unit you are using. 
Errors that come from the JTAG unit (such as Multi-ICE) are prefixed in the debugger 
by the string 

(JTAG)

. For a description of these errors, see the documentation that 

accompanies the JTAG unit you are using.

Errors from the RDI Module Server are prefixed with the string 

(MSVR)

 if you have 

enabled the module server when configuring RMHost (see Procedure for connecting to 
RMHost using AXD on page 22).

The error messages are as follows:

Cannot use RMHost as JTAG controller

This is displayed if you attempt to select 

RealMonitor.dll

 as the JTAG 

controller.

Configured JTAG controller DLL not compatible with RMHost

The configured JTAG controller DLL loaded successfully, and 
implements RDI, but it does not support a sufficient level of RDI to be 
used by RMHost. In this case, you must upgrade your JTAG controller 
software to be RDI 1.5.1rt-compliant.

Configured JTAG controller does not support RT extensions

JTAG controllers used by RMHost must support the real-time (rt) 
extensions to RDI. In this case, you must upgrade your JTAG controller 
software to be RDI 1.5.1rt-compliant.

Configured JTAG controller is not a valid RDI target

The DLL you have chosen for the JTAG controller does not implement 
RDI.

Data link timeout error

A link timeout typically occurs when the target is either not responding, 
or is responding very slowly. If the target is not responding at all, there is 
an error in the target. In this case, it is recommended that you either stop 
the target and examine its state directly using JTAG debugging, or reset 
the target.
