Data Loader




Data Loading Framework

Present within Accord is design and development experience for ARINC 615A compliant data loader used to load ARINC 665 compliant software parts on target LRUs via Ethernet. Support was added on PowerPC Platform LRU to support A615A dataloading and also for the download of Maintenance Data.

The design used the TFTP Application Layer Protocol with a lower level UDP-IP stack. This data loader was implemented with a modular architecture so that most functionality can be re-used as a library package.

On a recent project, an upgrade was performed to an existing Dataloading interface to change the underlying FAT-16 File System to a FAT-32 File System.

Accord has extensive experience working on different layers of the Dataloading Framework. Dataloading onto Flash Memories and Factory Loading of LRUs have also been taken up by Accord with good success.
