Hi
We opened Arduino through Mblock(v.1.6.5) and tried to upload Firmware_for_MegaPi onto our MegaPi board, but got this error:
avrdude: ser_open(): can’t open device “/dev/ttyUSB0”: Permission denied
ioctl(“TIOCMGET”): Inappropriate ioctl for device
ioctl(“TIOCMGET”): Inappropriate ioctl for device
avrdude: ser_send(): write error: Bad file descriptor
Problem uploading to board.
Can you explain why? Also how to resolve this problem?
Additional info:
Tried upload with both board on and off
Board option: Arduino/Genuino Mega or Mega2560
Processor option: ATmega2560(Mega 2560)
Port: Connected
