MicroROS not running as expected

[eden-desta]

Hello! So this is super new -- and kind of strange. My setup runs through the expected build process of what we need to do in order to build the firmware, flash it etc and then run the agent.

However, when i run the agent its stuck:

[1612884194.563610] info     | TermiosAgentLinux.cpp | init                     | running...             | fd: 3
[1612884194.563954] info     | Root.cpp           | set_verbose_level        | logger setup           | verbose_level: 6

I thought perhaps, i broke something in my own code (i was running using custom application). So i built another microros environment and tried to run the int32 publisher and the board was still stuck.

Is there anything that could be doing this? I just repulled the micro_ros_setup this morning and had not updated in over a month please let me know what your thoughts are!

Thank you!

Hello @edesta-be just this morning we have been updating critical sections of the codebase...

Could you retry the micro-ROS installation from scratch with the current state of the repos? If it does not work, could you please share with us some steps for replicating your situation?

[eden-desta]

For sure! I'll do so right now!

For a completely blank start:

source /opt/ros/foxy/setup.bash
mkdir microros_ws
cd microros_ws
git clone -b foxy https://github.com/micro-ROS/micro_ros_setup.git src/micro_ros_setup

sudo apt update && rosdep update
rosdep install --from-path src --ignore-src -y

colcon build
. install/setup.bash

ros2 run micro_ros_setup create_firmware_ws.sh zephyr nucleo_f746zg

ros2 run micro_ros_setup configure_firmware.sh int32_publisher --transport serial --dev 3

ros2 run micro_ros_setup build_firmware.sh
ros2 run micro_ros_setup flash_firmware.sh

ros2 run micro_ros_setup create_agent_ws.sh
ros2 run micro_ros_setup build_agent.sh
. install/setup.bash

ros2 run micro_ros_agent micro_ros_agent serial --dev /dev/serial/by-id/usb-STMicroelectronics_STM32_STLink_066FFF343039564157223210-if02 -v6

So same thing happens when i do this:

[1612885643.066215] info     | TermiosAgentLinux.cpp | init                     | running...             | fd: 4
[1612885643.066430] info     | Root.cpp           | set_verbose_level        | logger setup           | verbose_level: 6

It doesnt move past this point. I have pressed the RESET button on the board and tried flashing again. It doesnt work. This is for the int32_publisher using nucleo_f746zg. But I imagine if you dont have this board the same problem likely exists with the olimex.

I can try this again with another f7 board and see if it is potentially a hardware problem

[eden-desta]

Yes, so new board -- i didnt go through the entire build process because that would have been unnecessary just flashed it and tried running the agent again

ros2 run micro_ros_setup flash_firmware.sh
ros2 run micro_ros_agent micro_ros_agent serial --dev /dev/serial/by-id/usb-STMicroelectronics_STM32_STLink_066CFF343937424257252920-if02 -v6

It is definitely flashing it because i see the LED going off but the agent is still stuck on the startup two messages.

Try to use UART0 or change this, we have refactored the transports and I forgot to take into account the micro_ros_setup configuration...

Tomorrow I will check this again, let me know if this solution works.

[eden-desta]

Nice! I changed the extension to 3 and it worked! Nice

Thank you! Feel free to close this but in case you need it open to track i will leave it up to you! Thank you.

Let me know if you need me to test with your updates as well will be happy to help anyway I can!

[eden-desta]

It actually still exists with the custom application -- I'm going to revert my changes to the state of the software I previously had running and test it with a clean build

Hello @edesta-be, I'm closing this. Feel free to reopen if you have further problems!
