Embodiment Construction

[0013] 1. Write the CCP creation and start-up program according to the needs; initialize the CAN module according to the requirements of CAN2.0 A / B and the requirements of the CAN module chip data; at the same time complete the check of the RAM to be used; write the corresponding .c and . h file;

[0014] 2 Write the corresponding MAKE file and LINK file according to the needs of chip memory management and allocation;

[0015] 3 Compiling under the Unix system will generate the .S12 file and write it into the FLASH first, and the generated .A21 and .Hex files will be used as subsequent INCA configuration files;

[0016] 4 Connect the INCA card with the transfer adapter and then connect it to the CAN line, and communicate with the controller as a node on the CAN line;

[0017] 5 With the help of INCA, use CCP's PROGRAM, PROGRAM_6 command to write the program that needs to run on the controller into FLASH.

[0018] 6 Check whether MAGIC_NUMBER appears at the end of the command...

Abstract

A burning method for hybrid motor vehicle controlling FLASH burning by referring to INCA and CAN, comprises compiling CCP creation and start off program and the corresponding . c and . h documents, and corresponding MAKE and LINK documents, generating . S12 document under Unix system with writing to FLASH first, connecting the INCA card and adapter to the CAN cable and controller communication, writing to FLASH referring to INCA using CCP PROGRAM and PROGRAM-6. If it occurs with MAGIC-NUMBER, it shows a successful burning, otherwise, it needs to rework. The advantage is that the controller software update, diagnostic and re-burning is very convenient, cutting off the BDM interface from the controller hardware, reducing hardware design difficulty, and reducing the size of the controller.

Description

Technical field: [0001] The invention relates to a method for performing FLASH programming on a controller of a hybrid electric vehicle. Background technique: [0002] Today, with the rapid development of automobile technology, the application of control technology in automobiles is becoming more and more extensive, and it is often necessary to re-refresh, diagnose and update the controller software. In the past, the controller of the car needs to use the BDM to program the FLASH, so it is necessary to reserve a large space for the controller BDM interface when it is arranged; for a very compact car, this undoubtedly increases the layout. Difficulty; and once the controller is improperly arranged, when there is a problem with the software in the controller on the car or when the software needs to be updated, the controller is removed from the car and reprogrammed. After the programming is completed, the controller Installed, it is very difficult to update the controller sof...
