bdiGDB for GNU Debugger, BDI2000 (ARM11/Cortex-A8)

User Manual 28

STARTUP mode [runtime]This parameter selects the target startup mode. The following modes are supported:

 

HALT

This default mode tries to forces the target to debug

 

 

mode immediately out of reset. If successful, no code is

 

 

executed after reset.

 

STOP

In this mode, the BDI lets the target execute code for

 

 

"runtime" milliseconds after reset. This mode is useful

 

 

when monitor code should initialize the target system.

 

RUN

After reset, the target executes code until stopped by the

 

 

Telnet "halt" command. The init list is not processed in

 

 

this mode.

 

Example:

STARTUP STOP 3000 ; let the CPU run for 3 seconds

WAKEUP time

This entry in the init list allows to define a delay time (in ms) the BDI inserts

 

between releasing the reset line and starting communicating with the tar-

 

get. This delay is necessary when a target needs some wake-up time after

 

a reset.

 

 

time

the delay time in milliseconds

 

Example:

WAKEUP 3000 ; insert 3sec wake-up time

BDIMODE mode param

This parameter selects the BDI debugging mode.The following modes are

 

supported:

 

 

LOADONLY

Loads and starts the application code. No debugging via

 

 

JTAG interface.

 

AGENT

The debug agent runs within the BDI. There is no need

 

 

for any debug software on the target.This mode accepts

 

 

a second parameter. If RUN is entered as a second pa-

 

 

rameter, the loaded application will be started immedi-

 

 

ately, otherwise only the PC is set and BDI waits for GDB

 

 

requests.

 

Example:

BDIMODE AGENT RUN

ENDIAN format

This entry defines the endiannes of the memory system.

 

format

The endiannes of the target memory:

 

 

LITTLE (default)

 

 

BIG

 

Example:

ENDIAN LITTLE

VECTOR CATCH mask

When this line is present, the BDI catches exceptions. The mask is used

 

to setup the ARM Vector catch register.

 

mask

selects the exceptions to catch

 

Example:

VECTOR CATCH 0x1B ;catch Abort, Undef, Reset
