In the calibration module, the management of calibration data is also its core function. It mainly includes the following aspects: calibration data loading, calibration data exporting, calibration data brushing, and supporting application brushing. These functions are described in detail below.<\/h4>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

This operation is equivalent to the operation of loading a (hex,s19) file with the calibration software.

1\u3001Whether to select the application data<\/b><\/p>\n

Configuration 2 (Enable Application File) allows the user to choose whether to download the application data at the same time. Under normal circumstances, the ECU application data only needs to be reloaded after a new version is released, and the user only needs to download the calibration data separately after the calibration data has been modified.<\/span><\/span><\/p>\n

When the developer has released a new version of the application data, you need to check on configuration 2 and load the application data into the configuration, so that the application data and calibration data can be downloaded to the ECU at the same time when the download is done through the XCP protocol.<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

2\u3001Download speed difference<\/b><\/p>

The actual test of the controller of an East China host manufacturer revealed the following differences:<\/span><\/span><\/p>

When the App application is ready in the ECU, the download mode is non-Block download mode, i.e., a one-question-and-answer download;<\/span><\/p>

When the APP in ECU is erased, the download mode is Block download mode at this time.<\/span><\/span><\/p>

The difference in speed between these two download modes can be as much as 5-10 times different. Therefore, TSMaster specifically provides an erase mode to clear the internal APP program from the ECU. This is shown below:<\/span><\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Erase the ECU internal data first.<\/p>

2. Execute the download process again.<\/p>

With this approach, the swipe will be much faster than the direct execution of the download process, and the 0x3C0000 (2359296) bytes of data can be downloaded in less than 1 minute.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

1\u3001The ECU does not run properly after downloading<\/b><\/p>\n

\u27a2 Description of the phenomenon:<\/p>\n

The customer found that the ECU was not operating properly after the calibration data and application data were downloaded to the ECU. By comparing the messages, it was confirmed that all the data was downloaded to the correct address of the ECU, but the ECU was still working abnormally after starting.<\/p>\n

\u27a2 Cause Analysis:<\/p>\n

After troubleshooting, I found that the check type was not checked in the download module. The ECU's download process requires an internal check to confirm that the data file is correct after downloading the data. If there is no internal verification, the ECU will not dare to start without it, which means that the data inside the ECU is invalid.<\/p>\n

Solutions:<\/p>

Check the calibration option for the ECU, as follows:<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

2\u3001Slow connection speed<\/b><\/p>

\u27a2 Description of the phenomenon:<\/p>

When using the calibration module, some users have complained about the slow connection speed, such as taking more than a minute to complete an ECU connection.<\/p>

\u27a2 Cause Analysis:<\/p>

This is because when the calibration module connects to the ECU, it will first check whether the calibration data inside the ECU matches the calibration data in the calibration software. If it does not match, the data in the calibration software needs to be synchronized to the ECU, or the data in the ECU needs to be synchronized to the calibration software, as shown in the following figure:<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\n\t\t\t\t\t\t\t

In more extreme cases, the calibration file is not loaded in the calibration software at all, so the calibration data from the ECU needs to be read into the calibration software when the connection is made. When there is a lot of calibration data, this reading process is time consuming, which is why the connection process is slow.<\/p>

Solutions:<\/span><\/p>

Therefore, the solution is to load the calibration data file into the memory impression before connecting. When the ECU is connected and the calibration data in the ECU is monitored to match the calibration data in the software, there is no synchronization of the data and the ECU connection process is completed very quickly (measured in s).<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
