Error Handling during Software Updates

The AE300-Wizard uses several methods to ensure successful completion of the update pro-

cess or to guide the maintenance technician through situations of unsuccessful attempts or

aborts.

10.5.1

Pre-Flash Conditions

As indicated in chapter “10.2 Overview of the Software Update Process” on page 76, a set of

parameters (“pre-flash conditions”) will be checked by the AE300-Wizard to match the load-
ed flash container with the engine it is connected to. If a mismatch is detected, the AE300-

Wizard will report the type of mismatch (e.g. wrong engine type or revision incompatibilities)

and will abort the attempted update session. For example, trying to flash E4-B software onto

E4-A engine:

Another set of conditions is used to check the general situation of the engine (e.g. engine

stopped, aircraft on ground, battery voltage high enough, etc.) before commencing or abort-

ing the update session. For example, battery voltage is too low:

10.5.2

Automatic Retries

A hierarchy of retries has been implemented to ensure robustness for the connection to the

EECU, the data transfers and the programming of the ECU flash memory. If the retries re-

main unsuccessful, the update process will be aborted, the maintenance technician informed

about the reason of the abort and a restart of the update process will be suggested.

In case of loss or disruption of the CAN connection, automatic retries attempt to re-

establish the physical and/or logical connection (“Connect ECU”) to the EECU.

If the loss of connection lasts too long and a time-out occurs, manual reconnection by

the maintenance technician is required. After a manual reconnect, the AE300-Wizard will

then continue or restart the update process depending on the given situation.

In case of data transfer failures (e.g. due to electrical interference, cabling or connector

problems) up to 3 attempts to resend the data will be performed before an abort.

For flash memory erasure or programming problems, up to 3 retries will be attempted.
