Setting Up the AT91EB01 Evaluation Board
AT91EB01 Evaluation Board User Manual 3-9
6. Click on “Configure...”
7. If you are using both serial and parallel cables, select “Serial/Parallel from
Remote Connection”. If you are using only a serial cable, select “Serial”.
8. Select the serial and parallel communication ports, and the serial line speed.
(The AT91 Evaluation Board operates at up to 38400 bps.)
9. Click on “OK”.
10. To select little-endian mode, click on the Debugger tab, and click on “Little” in the
Endian selection.
11. Click on “OK”.
The debugger is restarted. The Restarting dialog box is displayed. Rapidly changing
numbers are shown, indicating reading and writing to the target.
Note: If the target board does not respond (the numbers in the Restarting dialog box
do not change), ADP times out within approximately five seconds and defaults
back to ARMulator.
When the configuration has completed successfully, a message similar to the following
is displayed in your host console window:
EmbeddedICE Manager (ADP ARM7TDI) 2.01 (Advanced RISC Machines)
When you start EmbeddedICE, it automatically defaults to a particular configuration
according to which version of the interface software is installed:
■
versions up to 1.03 default to ARM7DI
■
versions after this default to ARM7TDI
If any of the following messages are displayed when you start up the debugger or reload
an image, you must reconfigure the EmbeddedICE:
Error during initialization:
Recoverable error in RDI initialization
Target processor not stopped
Note: Ensure that the selected configuration is correct, otherwise problems may arise
when you run a program.
To configure the EmbeddedICE interface:
1. Choose “Configure EmbeddedICE” from the Options menu.
2. Do one of the following:
- Choose the name from the list and type in the version. You can usually type any
for the version. Click on “Select”.
- Load a new agent: click on “Load Agent...”, select the required agent file (usually
found in
ARM21x\Angel\Images\iceagent ), and then click on “Open”.
- Load a new configuration file: click on “Load Config...”, select the required configu-
ration file, and then click on “Open”. The required configuration data is usually
contained within the agent itself, so this option is seldom used.
3. Click on “OK”.
When the debugger closes down, the remote debugging option settings are stored in
memory. Thus at the next use of the debugger, the options may be recalled
automatically.
3.8.3 Configuring the
armsd Debugger to
Use EmbeddedICE When initializing armsd using EmbeddedICE, it is necessary to tell armsd the endian-
ness of the target. This contrasts with running Angel, or using ARMulator, where there is
a default endianness (little-endian).
To configure for a little-endian target using EmbeddedICE version 2.0 or later, the stan-
dard serial and parallel ports, and the default linespeed (9600 bps), enter:
armsd -li -adp -port s,p
To use serial port 2 (rather than serial port 1), and line speed of 38400, enter:
