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.
