compile and download to flash

Hi,
Thank you for your reply.

• I tried both make serialflash and stm32loader.py
ESPRUINO_1V3=1 RELEASE=1 make serialflash
sudo python scripts/stm32loader.py -a 0x8002800 -ew -k -p /dev/ttyACM0 espruino_1v81.26_espruino_1r3.bin
  
• ./scripts/create_espruino_image_1v3.sh
  this will create the bin with bootloader
  so I tried sudo python scripts/stm32loader.py -a 0x8000000 -ew -k -p /dev/ttyACM0 espruino_full.bin
  
  

still unknown device
