2.6.5 Using the Disk-on-Chip configure utility program
The command interpreter in
doc_configure.axf
accepts user commands from the
debugger console window and carries out actions to complete the commands on the
Disk-on-Chip subsystem.
Table 2-8 lists the commands for the Configure utility.
2.6.6 Redirecting character output to hardware devices
The redirection of character I/O is carried out within the Boot Monitor platform library
routines in
retarget.c
and
boot.s
. During startup, the platform library executes a
SoftWare Interrupt instruction (SWI). If the image is being executed without a debugger
(or the debugger is not capturing semihosting calls) the value returned by this SWI is
–1, otherwise the value returned is positive. The platform library uses the return value
to determine the hardware device used for outputting from the C library I/O functions.
(Redirection is through a SWI to the debugger console or directly to a hardware device)
