Troubleshooting¶

In case of any issue with software, read the Troubleshooting section of the 1x PDI Builder user manual.

Maintenance mode¶

Maintenance mode is the main troubleshooting tool that Veronte Autopilot 1x puts at the user disposal. While in maintenance mode, all communication channels are enabled by default, so it is possible to connect with Autopilot 1x 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.

While in maintenance mode, it is possible to perform actions such as force the load of a new configuration file or format the SD card.

If at some point the communication with Autopilot 1x is lost, it is possible to use maintenance mode to go back to 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 heavily 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 two ways to enter in maintenance mode: using software or forcing it.

Using software to enter in maintenance mode¶

To enter in maintenance mode using software, read the Maintenance Mode - Troubleshooting section of the 1x PDI Builder user manual.

Forcing maintenance mode¶

There are two ways to force the maintenance mode: using power supply or using the I2C pins.

Power supply¶

When communication with the unit is lost, it is possible to active maintenance mode by power input.

In order to active maintenance mode, power cycle the Veronte Autopilot 1x repetively with periods of 700 ms (with a margin range between 380 and 965 ms). After 30 cycles, the autopilot will enter in maintenance mode.

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

I2C pins¶

To enter in maintenance mode with I2C, unplug Veronte Autopilot 1x, connect both I2C pins each other, then power up Autopilot 1x, finally disconnect both pins. Both pins are I2C_CLK (number 31) and I2C_DATA (number 32) according to the pinout.

Note

Veronte Autopilots: Dev Harness 1x 4.8 (Embention reference P007043) has already included a button with this 2 pins to easily enter maintenance mode.

The procedure is the same as for the pins, but instead of connecting and disconnecting the pins, press and release the button.

Half-duplex servo does not respond¶

Any servo with half duplex RS-485 should communicate with Autopilot 1x following the connection diagram:

../_images/halfduplex.png — **Normal connection between 1x and servo**¶

Sometimes this connection does not work, because the servo has not enough transmission power. In this case, a couple of 10 \(\Omega\) resistors may solve the problem. Both resistors have to be placed at the trasmission line of the Autopilot 1x.

If the couple of resistors does not solve the issue, the user should contact the support team (create a ticket in the customer’s Joint Collaboration Framework; for more information, see Tickets section of the JCF manual).
