Error flashing HY32 Board

Yep, first time running again:

Reading data from espruino_1v41_hystm32_32_vc.bin
Bootloader version 0x22
Traceback (most recent call last):
  File "stm32loader.py", line 493, in 
    chip_id = cmd.cmdGetID()
  File "stm32loader.py", line 163, in cmdGetID
    if self.cmdGeneric(0x02):
  File "stm32loader.py", line 136, in cmdGeneric
    return self._wait_for_ack(hex(cmd))
  File "stm32loader.py", line 97, in _wait_for_ack
    raise CmdException("Chip replied with a NACK during %s" % info)
__main__.CmdException: Chip replied with a NACK during 0x2

Running it again:

Reading data from espruino_1v41_hystm32_32_vc.bin
Bootloader version 0x22
Chip id 0x414, STM32F1, performance, high-density
Traceback (most recent call last):
  File "stm32loader.py", line 508, in 
    cmd.cmdEraseMemory()
  File "stm32loader.py", line 242, in cmdEraseMemory
    self._wait_for_ack("0x43 erasing failed")
  File "stm32loader.py", line 87, in _wait_for_ack
    raise CmdException("No response to %s" % info)
__main__.CmdException: No response to 0x43 erasing failed

running it a third time puts it back to the first message Chip replied with a NACK during 0x43
