# About This is a Linux module/driver for USB to Serial converter built using Renesas μPD78F0730 microcontroller. This converter can be found on YRPBRL78G14 board and other development boards produced by NEC Electronics and Renesas Electronics. Using this driver you can program the board mentioned above with rl78flash, or communicate with main MCU through serial port with any terminal program you like. The driver is part of the Linux kernel since v4.11. # Build make # Install sudo make install You can verify that driver is registed by examining modules.alias file cat /lib/modules/$(uname -r)/modules.alias | grep upd78f0730 # YRPBRL78G14 notes Board can be used in 2 modes (selectable by jumpers CN6, CN7, CN8 and CN11): * OCD/programming (converter is connected to pin TOOL0 through one wire in half duplex mode, RTS is connected to RESET) * Virtual UART (converter is connected to UART0 in full duplex mode, RESET is not connected) Example: get information about target microcontroller (in OCD mode) rl78flash -inm3 /dev/ttyUSB0 # Copying/License Renesas Electronics uPD78F0730 USB to serial converter driver Copyright (C) 2014,2016 Maksim Salau <maksim.salau@gmail.com> This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation.
