I have tested the whole process with your board, here you have my session: https://asciinema.org/a/Vpcvaj7wgAqTRv8Y3Gbs8hoHp

The final error is that the board has not enough memory (this SoC has 24 kB? this will be challenging)... In any case, you can check this tutorial for tunning the micro-ROS memory usage.

Nice, I'm closing. Feel free to open another issue if you have further problems.

You should be able to use this component as it is with your boards if it is supported by Zephyr.

Did you have any problem?

Hi @pablogs9,

I first tried the following tutorial, but obviously my board is not in the supported ones, and so I cloned this repo, and executed the west build as follow:

and it gives me the above errors.
It's my first time with micro-ROS, any advice is really appreciated!

Ok definitely this SoC is not powerful enough, I will upgrade to the next version "ubx_bmd380eval_nrf52840". Following your video and compiling for this new board, it gives me no error! So when the board will arrive I think the flashing will be okay, I will let you know.

Thank you very much for your precious help!

Hi @pablogs9, the board is arrived and I flashed the built image, but it remains stuck in this function (as far as I can see with gdb):

(gdb) c
Continuing.
^C
Program received signal SIGTRAP, Trace/breakpoint trap.
0x000018de in main () at ../src/main.c:54
54		RCCHECK(rclc_support_init_with_options(&support, 0, NULL, &init_options, &allocator));

and on the agent side:

(base) manucar@D311:~$ docker run -it --rm -v /dev:/dev --privileged --net=host microros/micro-ros-agent:humble serial --dev /dev/ttyACM1 -v6
[1654605220.329402] info     | TermiosAgentLinux.cpp | init                     | running...             | fd: 3

I compiled the example on this repo with the same steps of your video (for the actual board: ubx_bmd380eval_nrf52840).
Do you think anything I can try?

Thanks!

Make sure that your board is reaching the PC via /dev/ttyACM1. Make sure that your serial ports are working ok before using it for micro-ROS client transport.

Manucar commented on May 28, 2024

Hi @pablogs9, okay after some debugging I find out that for some reason in this function for opening the transport layer:

bool zephyr_transport_open(struct uxrCustomTransport * transport){
    zephyr_transport_params_t * params = (zephyr_transport_params_t*) transport->args;

    char uart_descriptor[8];
    sprintf(uart_descriptor,"UART_%d", params->fd);
    params->uart_dev = device_get_binding(uart_descriptor);
    if (!params->uart_dev) {
        printk("Serial device not found\n");
        return false;
    }
...

the params->fd field was set to 1, so it was opening the UART_1, changing it to 0 -> UART_0 make it works.
