  Amazing, after all that troubleshooting to get make working, I failed to realize I should probably set the board to bootloader mode. That command worked great @Gordon, thanks much!

  I'm getting all the more excited about the Espruino project and its potential after seeing your dedication to it. I didn't quite expect a forum reply that late at night. :)

  I've cloned the Espruino repository with the intention of contributing to the JavaScript implementation (in as far as I can wrap my head around C). I've got an Espruino board, so I'm running make with ESPRUINO_1V3=1.

  I am on commit e4677650181132e9f883df9fbfeb4d4d3d60d3e9 when I'm doing all this. My machine is running Ubuntu 12.04 and I've installed all the compiler bits as far as I'm aware. (gcc, arm-none-eabi-gcc, and another one which name escapes me right now.)

  My full make command:

  ESPRUINO_1V3=1 BOARDNAME=1 make
  

  I haven't exported any other env variables prior to running make.

  Make exits with these last few lines, and an exit code of 0 (I think):

  LD espruino_1v54_espruino_1r3.elf
  GEN espruino_1v54_espruino_1r3.lst
  GEN espruino_1v54_espruino_1r3.bin
  bash scripts/check_size.sh espruino_1v54_espruino_1r3.bin
  PASS - size of 214252 is under 215040 bytes 
  

  Here's a full dump of make's output.

  Then, I'm running the loader:

  BOOT0=1 BOOT1=0 python scripts/stm32loader.py -k -p /dev/ttyACM0 -evw espruino_1v54_espruino_1r3.bin
  

  Which outputs:

  Reading data from espruino_1v54_espruino_1r3.bin
  Traceback (most recent call last):
    File "scripts/stm32loader.py", line 525, in <module>
      bootversion = cmd.cmdGet()
    File "scripts/stm32loader.py", line 140, in cmdGet
      if self.cmdGeneric(0x00):
    File "scripts/stm32loader.py", line 137, in cmdGeneric
      return self._wait_for_ack(hex(cmd))
    File "scripts/stm32loader.py", line 101, in _wait_for_ack
      raise CmdException("Unrecognised response 0x%x to %s" % (ask, info))
  __main__.CmdException: Unrecognised response 0x72 to 0x0
  

  Is there something wrong with the build, or the problem purely in loading it onto the board? I'd appreciate any pointers.
