Flash Programmer Mode
As flash writer at main unit, flash programmer mode is an S5U1C17001H operating mode for using it as a
standalone Flash programmer. This section describes the preparation and operations for using the Flash
programmer mode.
It is not used when debugging programs.
This operation is used only when the S5U1C17001H is used as a Flash programmer without a host computer for
mass production etc.
6.1
Preparation for Using Flash Programmer Mode
The S5U1C17001H is capable of programming data such as programs saved to the internal Flash memory
directly to the target system.
First save the Flash erasing/programming program (FLS program) and user program to the S5U1C17001H
internal memory as described below.
(1) Start up the S5U1C17001H in ICD mode.
Refer to "5.2 Activation in ICD Mode."
(2) Start up the debugger.
Refer to "5.3 Starting Up the Debugger."
(3) Save the FLS program corresponding to the target system (S1C processor) or external Flash memory to
the S5U1C17001H internal memory using the debugger (gdb) "fwlp" command.
(4) Load the data to be written to the target Flash memory to the S5U1C17001H using the "fwld" command.
(5) Quit the debugger.
For details of debugger (gdb) start/end procedures and how to create saf format files, refer to the
S5U1C17001C Manual (S1C17 Family C Compiler Package) or the S5U1C33001C Manual (S1C33
Family C Compiler Package).
6.1.1
fwlp Command
The debugger (gdb) "fwlp" command is used to save FLS programs for the target system (S1C processor) or
external flash memory in the S5U1C17001H internal memory.
