This is PC software to program RL78 microcontrollers via serial bootloader. This version can not set any security mode. Only S-record image files are accepted as input files. RL78/G10 parts can programmed only in 1-wire mode, other RL78 parts support both 1-wire and 2-wire modes. Reset signal is controlled by DTR or RTS signal.
$ rl78flash -viva /dev/ttyUSB0 R5F100SL.mot
See also output from $ rl78flash -h
If RESET pin of MCU is acting as GPIO it is no longer possible to enter bootloader mode without additional user actions. To enter bootloader mode it nessesary to power up MCU with RESET pin tied to ground.
Procedute to rewrite such microcontrollers:
- power down MCU
- start rl78flash tool with -d argument $ rl78flash -diva /dev/ttyUSB0 firmware.mot
- wait till message "Turn MCU's power on and press any key..."
- power up MCU
- press any key
- done.
