Hello
At input of a symbol $ restart redboot.
I add debugging messages in
ecos-trunk-full-060604\ecos\packages\redboot\current\src\main.c(383)
============
#ifdef CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS
if (res == _GETS_GDB) {
int dbgchan;
hal_virtual_comm_table_t *__chan;
int i;
// Special case of '$' - need to start GDB protocol
gdb_active = true;
// Mask interrupts on all channels
diag_printf("CYGNUM_HAL_VIRTUAL_VECTOR_NUM_CHANNELS =
%d\n",CYGNUM_HAL_VIRTUAL_VECTOR_NUM_CHANNELS);
diag_printf("Mask interrupts on all channels:\n");
for (i = 0; i < CYGNUM_HAL_VIRTUAL_VECTOR_NUM_CHANNELS;
i++) {
//
diag_printf("- channel %d\n",i);
//
CYGACC_CALL_IF_SET_CONSOLE_COMM(i);
__chan = CYGACC_CALL_IF_CONSOLE_PROCS();
CYGACC_COMM_IF_CONTROL( *__chan,
__COMMCTL_IRQ_DISABLE );
}
==============
At input of a symbol $ I receive:
CYGNUM_HAL_VIRTUAL_VECTOR_NUM_CHANNELS = 3
Mask interrupts on all channels:
- channel 0
- channel 1

What can it mean?
The '$' character is used to break into GDB - RedBoot is doing the right
thing, it's just silent about it.
If you need to type a '$' to RedBoot, precede it with \, e.g. \$
