6. Firmware Upgrade

To improve the device maintainability, CANFDCOM-100IE provides the IAP firmware

upgrade function. In the upgrade, use the RS232 port for firmware upgrade. There are two

upgrade methods:

Method 1: Upgrade from the configuration mode of the application. The method is the

most simple and convenient. The upgrade can be completed by simply pressing a few

buttons on the host computer software, but you need to ensure that the application

program can run properly; otherwise, only method 2 can be used.

First, connect the RS232 port, and set the configuration switch to "CFG" to enter the

configuration mode. In configuration mode, the configuration indicator is always on. The

upgrade can be completed by sending the firmware bin file by using the host computer

configuration tool. The procedure is as follows:

Step 1: Click the firmware upgrade button below the host computer configuration tool.

The firmware upgrade window appears, as shown in Figure 6.1;

Step 2: Select the path of the firmware file to be upgraded;

Step 3: Click the upgrade button. The configuration indicator will flash rapidly, indicate

that the firmware is being upgraded. At the same time, the COM indicator is solid on,

indicating that the data is transmitted properly. After the progress bar reaches 100% and

the upgrade completion confirmation box is displayed, the upgrade is completed. At this

time, the configuration indicator changes from fast flashing to steady light, indicating that

the upgrade is successful. If the actual situation is none of the preceding symptoms, the

upgrade is abnormal. Check whether the communication interface is normal and whether

the selected firmware bin file path is correct. If the upgrade exception damages the

application, method 1, which is simple, can no longer be used, and only method 2 can be

used.
