I need rpmsg_env_specific.h to user rpmsg-lite (new version) with Yocto Kirkstone and Zephyr upstream

[neuberfran]

Hi,

Realy I stay searching for "rpmsg_env_specific.h" because I can't found in https://github.com/nxp-mcuxpresso/rpmsg-lite/tree/main/lib/include Or in anywhere

[Hadatko]

Hello you need add include based on your target system: https://github.com/nxp-mcuxpresso/rpmsg-lite/tree/main/lib/include/environment

[neuberfran]

@Hadatko undefined reference to `z_impl_k_event_init'

I have other project(which is a copy of this) here(with old rpmsg_lite version) https://github.com/zephyrproject-rtos/zephyr/discussions/66669#discussioncomment-7908788 with errors in execution moment (not appear /dev/ttyRPMSG) But I can generate zephyr.bin at least

But in this project, I have one issue. Pls help-me I need test my project with new rpmsg_lite

Hi, if you mean linking error, then google is providing answer like this: https://stackoverflow.com/questions/74132932/zephyr-project-event-handling

[neuberfran]

@Hadatko Ok. But not Solved yet. Everytime stop in waiting for master....

[neuberfran]

@Hadatko I have all sorts of code with zephyr upstream, without success

printk("Waiting for Master.\r\n");
    // while (!rpmsg_lite_is_link_up(rl_instance)) {
    // }
    while (!rpmsg_lite_wait_for_link_up(rl_instance, 1000)) {       
    } 

    rl_queue = rpmsg_queue_create(rl_instance);
    rl_endpoint = rpmsg_lite_create_ept(rl_instance, LOCAL_EPT_ADDR,
                       rpmsg_queue_rx_cb, rl_queue);

But With Zephyr 1.13 (Original project transpose from warp7 device to imx7d-pico device) It's works

[neuberfran]

@Hadatko Pls help-me. I need rpmsg-lite in zephyr upstream https://github.com/zephyrproject-rtos/zephyr/discussions/66669#discussioncomment-7908788

[TomasGalbickaNXP]

Hello, @neuberfran Let me just try to point out what needs to happen to get out of "Waiting for Master.":

At Zephyr side you need to receive IRQ Callback from IPM from Linux side. https://github.com/neuberfran/diegosueiro/blob/main/rpmsg-lite/lib/rpmsg_lite/porting/platform/imx7d_m4/rpmsg_platform_zephyr_ipm.c#L20C6-L20C27

This call back has to go to env_isr https://github.com/neuberfran/diegosueiro/blob/main/rpmsg-lite/lib/rpmsg_lite/porting/environment/rpmsg_env_zephyr.c#L509

isr_table is set in function here: https://github.com/neuberfran/diegosueiro/blob/main/rpmsg-lite/lib/rpmsg_lite/porting/environment/rpmsg_env_zephyr.c#L426

And isr registration is done here: https://github.com/neuberfran/diegosueiro/blob/main/rpmsg-lite/lib/rpmsg_lite/porting/platform/imx7d_m4/rpmsg_platform_zephyr_ipm.c#L43 and here for remote TX side: https://github.com/neuberfran/diegosueiro/blob/main/rpmsg-lite/lib/rpmsg_lite/rpmsg_lite.c#L1107

And at the End this will trigger this tx callback which will get out rpsmg-lite remote out of waiting for master: https://github.com/neuberfran/diegosueiro/blob/main/rpmsg-lite/lib/rpmsg_lite/rpmsg_lite.c#L166

That means that the Linux side has to trigger this IRQ via IPM with correct link_id so it goes to above callback.

I recommend to try to debug this if you are getting at least IRQ from Linux side to Zephyr. That means if at lease this IRQ is triggered: https://github.com/neuberfran/diegosueiro/blob/main/rpmsg-lite/lib/rpmsg_lite/porting/platform/imx7d_m4/rpmsg_platform_zephyr_ipm.c#L20 If not something is not correct on Linux side. Where I cannot at the moment assist much.

Or even if you are getting any IRQ on IPM size with are maybe not propagated correctly here: https://github.com/neuberfran/diegosueiro/blob/main/rpmsg-lite/zephyr/samples/driver/ipm/ipm_imx.c#L36

If you boot Zephyr first via uboot it will stays at rpmsg_lite_wait_for_link_up and then its Linux time to sent it correct IRQ so it would be good to try focus here if IRQ from Linux is propagated here.

[neuberfran]

@TomasGalbickaNXP Thank you very much for the details friend. But, I don't think the problem is on the Linux side, because with the same Linux image (kernel=5.15, Kirkstone) I uploaded this project using Zephyr 1.13 (https://youtu.be/E34apiomZO4?si=e8YZgYdrSspPHPWo )(photos above) But the Zephyr upstream doesn't work. It may be that I find an error in Zephyr's CMakeLists.txt that is calling the wrong ipm_imx.

Second observation: My imx7d-pico board does not have a debug port.
