Firmware update failure after updating to Ubuntu 20.04

Ask
1

Hi all, I just updated our Stretch RE1 to Ubuntu 20.04. When trying to update the firmware, it fails at the wheels. I tried the fix here, but it was unsuccessful for me.

Any help would be appreciated!

$ REx_firmware_updater.py --install

Hi @lstegner, sorry to hear you’re experiencing this issue with the firmware updater! The firmware updater tool has the complicated job leading 6 Arduinos through a multistep firmware flash. The process is brittle since each step can fail in ways not caught or handleable by the tool. There’s definitely some work to be done with making this tool more robust! In the meantime, we’d still like to get your robot back up and running with the newest and safest firmware.

Here are some debugging steps that will give us the information we need to know:

  1. Reboot the robot (instructions here)
  2. Open a terminal and run:
    ll /dev/hello*
ll /dev/ttyACM*
  3. We’ll decide how to proceed based on the output we get from step 2.

Totally understand the complication. I really appreciate your support to get it running.

Here are the outputs:

$ ll /dev/hello*
lrwxrwxrwx 1 root root  7 Nov  4 10:53 /dev/hello-dynamixel-head -> ttyUSB1
lrwxrwxrwx 1 root root  7 Nov  4 10:53 /dev/hello-dynamixel-wrist -> ttyUSB2
lrwxrwxrwx 1 root root  7 Nov  4 10:53 /dev/hello-lrf -> ttyUSB0
lrwxrwxrwx 1 root root  7 Nov  4 10:53 /dev/hello-motor-arm -> ttyACM4
lrwxrwxrwx 1 root root  7 Nov  4 10:53 /dev/hello-motor-left-wheel -> ttyACM0
lrwxrwxrwx 1 root root  7 Nov  4 10:53 /dev/hello-motor-lift -> ttyACM1

crw-rw-rw- 1 root dialout 166, 1 Nov  4 10:53 /dev/ttyACM1

crw-rw-rw- 1 root dialout 166, 4 Nov  4 10:53 /dev/ttyACM4
crw-rw-rw- 1 root dialout 166, 5 Nov  4 10:53 /dev/ttyACM5

Thanks, looks like all of your robot’s USB devices still alias to hello-* correctly (e.g. ll /dev/hello* shows /dev/hello-motor-right-wheel -> ttyACM2), which is good news! In total, there are 10 hello-* aliases, and 6 Arduinos (which show up as ttyACM[0-9]).

After the right wheel failed to flash initially, the hello-pimu, hello-wacc, and hello-motor-lift devices didn’t get updated, so let’s update them individually now:

REx_firmware_updater.py --install --pimu
REx_firmware_updater.py --install --wacc
REx_firmware_updater.py --install --lift

The next step will depend on if these 3 flash successfully.

I believe it all ran successfully! The only thing was that all three outputted the same message about post firmware updates:

Great, I believe we can ignore the usb.core parse errors for now since both steps of the firmware flash completed successfully for these 3 devices. I plan to investigate the errors later.

Let’s continue by reflashing the remaining 3 devices, including the wheels, to confirm that both steps of the firmware flash complete successfully.

REx_firmware_updater.py --install --arm
REx_firmware_updater.py --install --left_wheel
REx_firmware_updater.py --install --right_wheel

Afterwards, let’s confirm all 6 devices are at the latest using:

REx_firmware_updater.py --current

We’ll decide what to do next based on what the above commands return.

Great! Looks like all 6 boards are happily upgraded. Let’s reboot the robot and run the following two commands to home and system check the robot:

stretch_robot_home.py
stretch_robot_system_check.py

If both execute without failure, then you’re all set! The final post-install step would be to configure the Dex Wrist if you’re using it.

Thank you so much! The homing and system check ran as expected :slight_smile:
No dex wrist to set up, so I guess everything should be working now.
