Hello everyone, I am Mirko, and today we see how to do the firmware update of the CL Racing F4 flight controller First we download the RC driver fixer impulse, you can find the link in the description. We start the software and connect the flight controller to the PC The drivers are installed automatically and at the end of the procedure the program closes. Now we press the boot button, connect the usb cable and start betaflight. As you can see we are in DFU mode which allows us to do the firmware update. Let’s click on FIRMWARE FLASHER In this menu we choose the taget, we select CLRACINGF4 Here we choose the firmware version, I recommend that you always use the latest version available. We enable FULL CHIP EREASE and click LOAD FIRMWARE ONLINE After we click Flash Firmware Once the process is finished the new firmware is installed, so we can connect. Now we can configure the board according to the components we have installed in our build. This was my tutorial on how to update the firmware of CL Racing F4.
