Amforth has a kind of bootloader built-in, since it constantly flashes new words defined. I am doing so-called in-line serial programming with two Arduinos (cheap AVR development board with USB - http://www.arduino.cc/) connected to each other. One runs the flasher (not yet in Forth, but soon!) and the other one is being flashed. I don't even have a programmer here. Actually we have a project with 4 AVRs connected to another one (a master) via the SPI interface, and we will probably try to test re-programming them on the fly via SPI (exciting possibility of a really self-replicating, self-deploying distributed programming). There is also possibility to flash the Arduino board completely in-line via the FTDI chip that is on-board there, but one needs to solder a small 4-pin header to the board and it's kind of slow, but works great in emergency. //Marcin ------------------------------------------------------------------------------ Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev _______________________________________________ Amforth-devel mailing list Amforth-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/amforth-devel
