Failed to upgrade Rotrics DexArm's Firmware
If the upgrade failed, the machine will be stuck in the bootloader and could execute the loaded application. You can see there is a green LED blinking inside the 12-pin port aka Port 1.
In that case, we need to use third-party software to upgrade the firmware. Please follow the instruction to updated the firmware.
Before going through the firmware update, make sure your DexArm has connected to your computer and open Device Manager to check the COM port.
It should be an STM Virtual COM Port. If couldn't find it, make sure the cable is physically connected.
