Step 4 - PropPlug Headers

The Propeller Platform SD comes programmed with a bootloader. You can copy a binary to an SD card & it will run that binary;

1 - name the binary 'run.bin' and copy to the root directory on your microSD. Insert it and flip the Prop Platform SD on. It will load run.bin to RAM and delete the run.bin file off the SD card.

2 - if you put a file alongside run.bin called 'nodelete.txt', the Propeller will load up run.bin, but won't delete it off the SD card

3 - if you call the file update.pgm, the propeller will load that binary to the top half of EEPROM. If you reset the Prop without an SD card, it will start running the program in the upper half of EEPROM.

4 - Finally, you can update the bootloader - copy the binary to SD card with the filename 'loader.pgm', and the Propeller will boot up and copy that binary to the lower half of EEPROM, overwriting the bootloader.

 

If you're using a PropClip, you won't need to add headers, connections are right on the edge. Also, there's a 5th hole marked 'V33'. This is for advanced users that want to power the Propeller directly from a programming plug, or have their programming plug receive 3.3V from the Propeller Platform SD.
