RL78 - DIY programmer

Note for Windows users:

Since rl78flash is a linux tools that heavily relies on POSIX syscalls (ioctl, etc.) it cann't be directly used under Windows OS.

But it can be used through Cygwin library. Precompiled binary for windows is available in downloads section: https://github.com/msalov/rl78flash/downloads

Cygwin library is included. If you have cygwin already installed and it is accessable with PATH, you don't need cygwin1.dll from archive.

Example (read information about device, use single-wire connection through COM10, reset is generated by DTR pin):

rl78flash.exe -m1 -vvi /dev/ttyS9

Small update.

I've made board " with buffers and USB power/data connectivity" :)

Here is schematic (click to view full-size image)

Host software is the same: https://github.com/msalov/rl78flash

Support for Windows OS has been added already. Native precompiled version for Windows (no cygwin, or other POSIX emulation layer) can be downloaded here: https://sites.google.com/site/eemaxfiles/rl78flash

@Maxim, I've got the RL78 cross compiler built, built up DJs flash util, but am having a bit of a time getting your source to compile under OSX. I keep getting errors in serial.c from what looks like issues with one of the includes but can't seem to figure out which one it's missing.  I've added term.h to reference TCFLSH which seams to be giving me problems but still has issues.  which environment were you building it under on GCC?

Maxim Salov:

I'd like to read-write RL78 / G13

made to the hardware by your scheme

I have to have the axis of software that can run rl78flash software in Win XP?

thank you

Hi to all. Am newer to the renesas controller. I am using R5F102AAA. am having Windows 10 OS. am installed Cygwin.  Am confused for the next stage. if any one available then kindly given the details for serial programming. Am already prepared the hardware based on the given circuit. thanks in advance

You can use the hardware and software to write RL78/G13, but you cannot read the memory.
In fact, there's no way you can read the memory, just compare a file with the memory data is possible.

Thank you,

Andre

Hi Uva,

Did you download the windows tools from here?

https://github.com/msalau/rl78flash/releases/download/v0.7.0/rl78flash-0.7.0-win64.zip

The usage examples are very clear too:
