Detailed Description

Transfers a complete segment to the ECU as fast as possible

To reprogram an ECU, the data to be flashed must first be determined from the MVCI server via Flash.GetDownloadData and then sent to the ECU in blocks via DiagCom.ExecuteDiagService. This requires the data to be transferred from the MVCI server to the OTX runtime and back to the MVCI server. Depending on the implementation, this can be done across multiple software layers. Due to the generally large amount of flash data, this can take a long time. With the Action TransferSegment, the implementation can be optimized in such a way that the data no longer runs through all software layers, thus achieving a significant increase in performance. The term Flash.GetDownloadData and the action DiagCom.ExecuteDiagService no longer have to be used for flashing.

Syntax: FlashPlus.TransferSegment(ComChannelTerm comChannel, FlashSessionTerm session, NumericTerm blockIndex, NumericTerm segmentIndex, NumericTerm transferBlockSize, IntegerVariable transferredBytes);

Examples: // Local Declarations

DiagCom.ComChannel ComChannel1;

DiagCom.DiagService DiagService1;

Flash.FlashSession FlashSession1;

List<String> flashSessionNames;

Integer transferredBytesVar;

Boolean Result = false;

// Flow

// using DB 992_14_x_Flash.FULL, 992_CAN

ComChannel1 = DiagCom.GetComChannel("LL_GatewUDS", NULL, false);

DiagService1 = DiagCom.CreateDiagServiceByName(ComChannel1, "DiagnServi_ReadDataByIdentVWSparePartNumbe");

DiagCom.ExecuteDiagService(DiagService1);

flashSessionNames = Flash.GetListOfValidFlashSessions(ComChannel1, NULL, @Directions:DOWNLOAD);

FlashSession1 = Flash.GetFlashSession(flashSessionNames[0]);

FlashPlus.TransferSegment(ComChannel1, FlashSession1, 2, 0, 255, transferredBytesVar);

Result = transferredBytesVar == 4456208;
