I'm using Linux 6.6.94
On my dmesg I have this message
[ 3286.891586] virtio_rpmsg_bus virtio0: msg received with no recipient
and I have this extract on my firmware code

int32_t status = ipc_lib_init(callback);
#if MCU_SUPPORT_DEBUG
DebugP_log("[APP] IPC initialized. Sending welcome message to A53...\r\n");
#endif
const char* welcome_message = "Hello from MCU! IPC is ready.";
// Send welcome message
ipc_lib_send(A53_MAIN_CORE_ID,
A53_CHRDEV_ENDPOINT,
welcome_message,

#if MCU_SUPPORT_DEBUG
DebugP_log("[APP] Welcome message sent. Entering main polling loop.\r\n");
