Linux 问题：Virtio rpmsg 总线 virtio0：收到的 msg 没有收件人 在 Yocto Hardknott imx7dpico

我正确地生成了Yocto Hardnott Technesion的图像:

$ mkdir tn-imx-yocto
$ cd tn-imx-yocto
$ repo init -u https://github.com/TechNexion/tn-imx-yocto-manifest.git -b hardknott_5.10.y-next -m imx-5.10.52-2.1.0.xml
$ repo sync -j8
$ DISTRO=fsl-imx-x11 MACHINE=pico-imx7 BASEBOARD=pi source tn-setup-release.sh -b build-x11-pico-imx7
$ bitbake core-image-base

在我运行modprobe imx_rpmsg_tty之后，我遇到了一个问题:virtio_rpmsg_bus virtio0: msg received with no recipient

我试过这个:https://community.toradex.com/t/rpmsg-error-virtio-rpmsg-bus-virtio0-msg-received-with-no-recipient/12701

当我将第83行和第102行从src改为dst时，我得到了下面的错误(也请看最后一张照片):

/home/neuberfran/freertos-tn/examples/imx7d_pico_m4/demo_apps/rpmsg/str_echo_freertos/str_echo_freertos.c: In function 'StrEchoTask':

The error is being printed on line 761: https://elixir.bootlin.com/linux/latest/source/drivers/rpmsg/virtio_rpmsg_bus.c#L761

如何解决？

编辑:我认为问题可以留在Vring[0]Vring1.链接如下.因为我可以

#define VRING0_BASE     0xBFFF0000
#define VRING1_BASE     0xBFFF8000 

在平台信息中.c但是我不能在imx_rpmsg中进行更改.C
