Setting Up the AT91EB01 Evaluation Board

AT91EB01 Evaluation Board User Manual
3.10.1
Serial Host
Connection
Connect the host computer to the Serial A port USART on the AT91 Evaluation Board
using a 9-pin RS-232 cable. Power up the board (see “Powering Up the Board” on page
3-2).
3.10.2
Configuring the
ARM Debugger for
Windows to Use
Angel
To configure the ARM Debugger for Windows (ADW) to access Angel rather than the
ARMulator:
1.
Start the ADW (not via the ARM Project Manager). In its default state, a mes-
sage similar to the following is displayed:
ARMULATOR 2.0 [Jan 6 1997]ARM7DTMI, 15.0MHz, 4Gb, Dummy MMU, Soft Angel
1.4,[Angel SWIs, Demon SWIs],FPE, Profiler, Tracer, Little endian
2.
Choose “Configure Debugger...” from the Options menu.
3.
Click on the “Target” tab.
4.
Select “Remote_A”.
5.
Click on “Configure...” and select “Serial”.
6.
Select the serial communication port and line speed. (The AT91 Development
Board operates at up to 57600 bps).
7.
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 mes-
sage similar to the following is displayed in the host console window:
Angel Debug Monitor (serial) 1.04 (Advanced RISC Machines SDT 2.11a) for
AT91EB0x(1.01)
Angel Debug Monitor rebuilt on Sep. 14 1998 at 14:52:22
Serial Rate: 38400
3.10.3
Configuring the
armsd Debugger to
Use Angel
To operate armsd with Angel using a serial connection, type:
armsd -li -adp -port s=1 -linespeed 38400
where:
-li
is the little endian switch
-adp
is the switch to allow communication using ARM Debug
Protocol required by Angel
-port s=1
indicates that the serial port is port 1 on the host com-
puter.Type the serial port number (1 or 2) or the host device
name
-linespeed 38400
sets the baud rate for serial communications between the
host computer and the Development System
When this command is entered, the host displays the debugger's opening banner, which
will be similar to:
A.R.M. Source-level Debugger vsn 4.46 (Advanced RISC Machines SDT2.10) [Dec
13 1996] Angel Debug Monitor for AT91 (serial) 1.04 (Advanced RISC Machines
SDT 2.11a)
Note:
The options available for armsd can be viewed by typing armsd -h at the com-
mand line.
3.11
Using Angel
Angel has been ported on the AT91EB01 so that the majority of features of the
AT91M40400 are available to the application. The Angel Debug Monitor is intrusive.
Therefore, this implies some limitations on the use of the resources:
■
USART 0 is reserved for communications with the debugger.
