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.
