Error codes

Should something go wrong during the execution of your program, an error code will be displayed. If you have a device with more program memory (like the Arduino Mega), build Octoduino with the build options CRASH_MSG_DETAIL and CORE_STACK to see more detailed error messages along with a descriptive app stack dump.

By default, when an error is encountered, the system will display an error message and then halt. If you build Octoduino with the build option CRASH_REBOOT, the system will restart upon a crash (may cause an infinite crash loop if error lies in program code).

Ex001

Error initializing Serial output channel.

Causes:

  • Waiting for PC serial connection loop timed out.

Possible fixes:

  • Make sure you have a Serial console open when the device is booted.
  • Build without the option IO_LOG_SERIAL.

Ex002

Error initializing SD log output channel.

Causes:

  • SD card is not fully inserted.
  • SD card is corrupted.
  • Another device or IO channel is using the required SS/data pins.
  • Your shield does not use pin 4 for data.
  • Your shield is incorrectly seated.

Possible fixes:

  • Format the SD card to FAT16 or FAT32.
  • Use a different SD card.
  • Make sure the card is not marked as read-only.
  • Verify that your shield uses pins 4/10. If not, use the GUI builder to change it.
  • Make sure that your shield is fully inserted.
  • Make sure that any non-shield device is using pins 4 and 10.

Ex003

Error initializing LCD output channel.

Causes:

  • The LCD library could not interface with the LCD device.

Possible fixes:

  • Make sure that your wiring is correct.
  • Check your LCD device for damage.
  • Ensure that no other devices are using the data lines.

Ex004

Error writing to log on SD card.

Causes:

  • SD card is not fully inserted.
  • SD card is corrupted.
  • Another device or IO channel is using the required SS/data pins.
  • Your shield does not use pin 4 for data.
  • Your shield is incorrectly seated.

Possible fixes:

  • Format the SD card to FAT16 or FAT32.
  • Use a different SD card.
  • Make sure the card is not marked as read-only.
  • Verify that your shield uses pins 4/10. If not, use the GUI builder to change it.
  • Make sure that your shield is fully inserted.
  • Make sure that any non-shield device is using pins 4 and 10.
