Anyone know the specifics of how FoUSB loads the monitor?

From the broken English in the FoUSB manual, it appears that the FoUSB downloads the monitor program into the 30626, but I haven't found any mention of how this is done. I assume it's documented somewhere, but has anyone found it? I've looked through the serial port section in the hardware manual without any luck.

Are there any third party or open-source alternatives to the FoUSB?

Thanks,

Bob

There is a section in the manual under: Running FoUSB (Flash-over-USBTM) Programmer.

I m not sure if its clear but if you open FoUSB and click on the Select MCU button and select your MCU's model.

It should reprogram the board. Does this answer your question?

Sorry, is this still valid?
Do you want to use FoUSB only for programming the device, or for debugging your code with KD30 or the HEW debugger?

If you use it only for programming FoUSB does not download anything except your software. The device has a bootloader programmed and FoUSB uses this to write the code.
For flash programming in UART mode you can also use the Renesas Flash Starter software (called M3A-0806) (http://www.renesas.com/fmwk.jsp?cnt=m3a_0806.jsp&fp=/products/tools/flash_prom_programming/flash_programmers/m3a_0806/) or use M16C-Flasher (http://www.m16c-flasher.de/).

If you use it for debugging FoUSB downloads the debug monitor software to 0xFF900 - 0xFFE80. This monitor software is programmed every time you download your application software. This download is also done using the bootloader software flash programming.
