Chapter 6: Solving Problems

Solving Target System Problems

Solving Target System Problems

This section describes how to determine whether your target system is
causing problems with the operation of the emulation module.

What to check first

1

Try some basic built-in commands (using the Command Line
window or a serial or telnet connection):

U>rst
R>

This should reset the target and display an “R>” prompt.

R>b
M>

This should stop the target and display an “M>” prompt.

M>reg r1

reg r1=00000000

M>

This should read the value of the r1 register (the value will probably be
different on your target system).

M>m 0..

00000000 7c3043a6 7c2802a6 7c3143a6 4bf04111
00000010 00000000 00000000 00000000 00000000

00000040 00000000 00000000 00000000 00000000
00000050 00000000 00000000 00000000 00000000
00000060 00000000 00000000 00000000 00000000
00000070 00000000 00000000 00000000 00000000

M>

This should display memory values starting at address 0.

M>s

This should execute one instruction at the current program counter.
