    I've recently posted the sources to p1load to github. p1load is a command line program for loading Spin binaries. It also includes a module called ploader.c that implements the Propeller ROM loader protocol and can interface to any serial driver that can provide an appropriate interface. This interface currently consists of a tx() function to transmit a buffer of bytes, an rx_timeout() function that receives a buffer of bytes with a timeout, and a reset() function that resets the Propeller, usually by toggling the DTR signal.

    p1load can be built for Mac OS X, Linux, or Windows.

    p1load - a simple loader for the propeller - version 0.009, 2014-08-10
    usage: p1load
             [ -b baud ]               baud rate (default is 115200)
             [ -p port ]               serial port (default is to auto-detect the port)
             [ -e ]                    write a bootable image to EEPROM
             [ -P ]                    list available serial ports
             [ -r ]                    run the program after loading
             [ -t ]                    enter terminal mode after running the program
             [ -T ]                    enter PST-compatible terminal mode
             [ -v ]                    verbose output
             [ -? ]                    display a usage message and exit
             file[,addr]...            files to load
    

    So if I write the rx_timeout(), tx(), and reset() functions ploader.c should compile into a stand alone command line aplication with out any problem on RISC OS?

    That seems easy enough, cool.

    Maybe. But p1load assumes Posix terminal functions to configure its simple terminal emulator.

    That is OK, a terminal emulator is something that can be whipped up fairly quickly.

    As long as I can get the propeller to load I am good.
  • Can I use p1load with the Propeller without any external component (no eeprom), just by having the chip and plugging RX TX and RESET? Or I need at least a crystal? This will load directly to RAM if I don't use the -e option, right?

    Yes, you should be able to use it without an EEPROM or crystal.
