FAQ

• Error: "Failed to open /dev/ttyACM0: Permission denied"

  Run NANDO as root or add following udev rule for permanent configuration:
  /etc/udev/rules.d/50-nando.rules

  SUBSYSTEMS=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="5740", MODE:="0666"

• Error: "Failed to open /dev/ttyACM0: Device or resource busy"

  Modem manager tries to detect USB device. Wait a minute or stop Modem manager:

  sudo service ModemManager stop

• Read ID shows 0xFF 0xFF..., 0xFE 0xFE... or other pattern

  The chip is not properly connected to the board. The problem can be one of the following:
  - TSOP-48 socket does not provide reliable connection for unsoldered NAND because pins are not flat. Try to use a "soldering adapter" or adjust NAND in the socket.
  - No connection between MCU and adapter/NAND. Try to check connections by tester.
  - Stray capacitance. Make sure no flux leftovers after soldering.
  - Chip is not supported. Check pinout and voltage are supported.
  - Wrong configuration. If a new chip was added make sure configuration is correct.
  

• Which MCUs project supports?

  Currently only one MCU STM32F103VCT6 is supported. The project can be ported to MCU which contains FSMC and SPI interfaces, 256MB flash and 64 SRAM.
