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.

Windows System‌

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.

1) Download Tera Term software and the newest version of the firmware.

2) Connect Rotrics DexArm to your PC with the USB A-C cable‌

3) Launch Tera Term software, selectSerial, choose the corresponding COM port, click OK

You can also click​ File -> New Connection​ to connect DexArm

‌4) Send command​ M2002 ​to start preparing mode, send ​M2003 ​to enter Boot Loader mode.

‌The software won't display the commands during inputting, just type in and hit enter.

‌5) Send ​5​, check the hardware version, it should be V3.1 or V3.2, send ​1​ to enter firmware uploading mode.

6) Click​ File - Transfer -> YMODEN -> Send​, select the ​corresponding firmware​ and click ​Open​

❗Warning: Make sure you've selected the corresponding firmware version, check your hardware version and select the correct firmware: if your ​hardware version is V3.1​, select the ​Firmware_V2.1.x_For_Hardware_V3.1_xx. The ​Firmware_V2.1.x_For_Hardware_V3.2_xx ​is for​ hardware version V3.2.

​‌7) Wait for the firmware burning process to finish

After finished, you will get a successful message as below.

Try again and again until you get the successful message output.

You will get the Main Menu output once DexArm has been rebooted.

8) Send ​3​, start the program of the newest firmware version.

9) Close Tera Term software, open Rotrics Studio to start using your Rotrics Arm.‌

Mac OS System‌

Watch the tutorial video to upgrade Rotrics's firmware on Mac

Or follow the step-by-step instructions below:‌

1) Download the Serial 2 software and Rotrics Firmware‌

Click ​Try Free​

2) Connect Rotrics Arm to your Mac with the USB A to C cable and power on‌

3) Launch​Serial 2​, click ​USB ​to select Rotrics Arm and click ​Open​

4) Send command​ M2002 to start preparing mode, send​ M2003​ to enter Boot Loader mode.‌

💡Tips: Jump to Step 5 if you see a blinking LED in port 1.

💡Tips: The Serial 2 software will discount with Rotrics after sending M2003. We need to re-open the Serial 2 software.

‌5) Send ​5​, check the hardware version, it should be V3.1 or V3.2, send ​1​ to enter firmware uploading mode‌

💡Tips: After reconnecting, the screen will be blank, send 5 and it will show the hardware info.

‌6) Click File - Send File, select the corresponding firmware and click ​Send File​

❗Warning: Make sure you've selected the corresponding firmware version, check your hardware version and select the correct firmware: if your ​hardware version is V3.1​, select the ​Firmware_V2.1.x_For_Hardware_V3.1_xx​. The ​Firmware_V2.1.x_For_Hardware_V3.2_xxx ​is for​ hardware version V3.2.

​‌7) Select ​YMODEM ​transfer protocol, click send and wait for the firmware burning process finish

‌❗Notice: Serial 2 won't show the successful message after burning. Under our test, it's 100% successful.‌

8) Send ​3​, start the program of the newest firmware version.

9) Reconnect DexArm and send M2010 to check the firmware has been updated.

10) If success, close ​Serial 2 ​software, open Rotrics Studio to start using your Rotrics Arm.

‌‌

Tips: Jump to Step 5 if you see a blinking LED in port 1 at the back of DexArm.

Tips: If fail(the progress bar disappears before 100%), send ​a​ to cancel burning and send 1 to re-enter firmware uploading mode and repeat steps 5) and 6).‌

Tips: If Tera Term outputs "Verification failed!", shown as below, please send 4 to disable the write protection and the system will restart.

Tips: If ​Tera Term​ outputs ​Invalid Number​ and ​Start program execution ​show as below, please reboot the machine and repeat Step 5 and the rest.

No need to close Tera Term.
