## NAME

m16c-flash - Flash programmer for Renesas M16C and R8C microcontrollers

## SYNOPSIS

**m16c-flash** \[**COM\_DEV**\] \[**CPU\_TYPE**\] \[**FILE**\] \[**ID1:...:ID7**\] \[**OPTIONS**\]

## DESCRIPTION

**m16c-flash** is a flash programmer for the Renesas M16C and R8C microcontrollers which operates in asynchronous mode.

## OPTIONS

**COM\_DEV** The serial device to use for flashing, e.g. /dev/ttyS0 or /dev/ttyUSB0.

**CPU\_TYPE** The CPU type you want to flash to (currently M16C or R8C).

**FILE** The filename of the binary you want to flash.

**ID1:...:ID7** The device ID.

**--help** Show a help text and exit.

**--version** Show version information and exit.

## EXAMPLES

Flash the simple.s file onto an M16C microcontroller via the first serial port (/dev/ttyS0) using 0:0:0:0:0:0:0 as the device ID:\
 **m16c-flash /dev/ttyS0 M16C simple.s 0:0:0:0:0:0:0**

Flash the test.mot file onto an R8C microcontroller via the USB serial device /dev/ttyUSB0, and using ff:ff:ff:ff:ff:ff:ff as device ID:\
 **m16c-flash /dev/ttyUSB0 R8C test.mot ff:ff:ff:ff:ff:ff:ff**
