Troubleshooting

In case of any issue with an Autopilot 1x located in Autopilot 4x, read the Troubleshooting section of the 1x PDI Builder user manual . Otherwise, in case of any issue with the Management Board, read the Troubleshooting section of the 4x PDI Builder user manual .

Warning

Select your version before reading any user manual for software. The following image shows where to select a version from any Embention user manual.

Maintenance mode

Maintenance mode is the main troubleshooting tool that Veronte devices have at the user disposal. While in maintenance mode, all communication channels are enabled by default, so it is possible to connect with them through any of its configuration interfaces, no matter its current configuration.

The main use of maintanance mode is to solve issues related to the current configuration, mainly related with communication or memory writting issues.

The maintenance mode allows to perform actions such as force the load of a new configuration file or to format the SD card.

If at some point the communication with an inner autopilot 1x or the Management Board is lost, it is possible to use the maintenance mode to restore a previous state of the configuration (as long as it was exported previously), format the SD card to start over or update the unit’s firmware.

Tip

It is strongly recommended to always use maintenance mode to load a new configuration that is very different from the current one.

How to enter in maintenance mode

There are three ways to enter in maintenance mode: using software, power supply or I2C pins.

Using software to enter in maintenance mode

To establish the state of an inner Autopilot 1x as maintenance mode with software, read the Maintenance Mode - Troubleshooting section of the 1x PDI Builder user manual.

To use the maintenance mode for the Management Board with software, read the Maintenance Mode - Troubleshooting section of the 4x PDI Builder user manual.

Using the power supply to enter in maintenance mode

When communication with the Autopilot 1x or the Management Board is lost, it is possible to active maintenance mode using the power supply input.

In order to active maintenance mode, power cycle the Veronte Autopilot 1x or the Management Board repetively with a period of 1 second. After 30 cycles, the device will enter in maintenance mode.

How to power cycle an autopilot

Autopilot 1x and Management Board might enter in maintenance mode if a problem with the power supply is detected upon boot up (voltage or current is out of range).

Using the I2C pins to enter in maintenance mode

To use a Management Board with maintenance mode employing I2C, connect both I2C pins each other, then power up the Management Board and the three inner autopilots. Both pins are SCL_A_OUT_ARB (number 39) and SDA_A_OUT_ARB (number 40) according to the Arbiter Connector pinout.

Note

It is possible to enter in maintenance mode using I2C pins with an inner autopilot; however, it requires to connect both I2C pins and select the desired autopilot with the Management Board. This method is not recommended for inner autopilots, since the software and power supply methods are easier.
