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.

RUNAfter 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
