Tool/software:
Hello,
we want to implement a shared ethernet connection between R0 (FreeRTOS) and A53 (Linux) on the AM6442.
ICSSG Port is used for ethernet netif. The intercommunication interface is initialized. The two netifs function as ports of the bridge.
icmp.c is fixed that the bridge is able to answer on pings. This works already.
Bootflow / Behavior:
R0 starts R1..3 and Linux.
We wait for Linux to be booted equivalent to the mcu+ (version 11.00.00.15) and industrial (version 11.00.00.08) SDKs examples with the function: RPMessage_waitForLinuxReady()
In the bootprocess of Linux, this function of R0 Core is returned with success.
After that, we register a Callback and send the announcement with:
#define LINUX_CHANNEL_ENDPT_ID 13
#define IPC_RPMESSAGE_SERVICE_PING "ti.icve"
RPMessage_announce(CSL_CORE_ID_A53SS0_0, LINUX_CHANNEL_ENDPT_ID, IPC_RPMESSAGE_SERVICE_PING);
Problem:
At the Moment, we have to send the announcemessage in a 2 second interval in a while loop until we receive a message!
Linux does not register the rpmsg channel immediately nor correctly. It registers the announce message between 15 to 300 seconds after boot, very undeterministic. When linux registers the answer, it does not create the rpmsg channel. An ethernet interface is created. The rpmsg response from linux is registered in the R0 by the callback but is not the request for shared memory information, what we would expect.
Assumption:
The described behavior causes most likely a faulty or no configuration of the shared ethernet....
There could be a problem in the device tree regarding the mbox mode, where we are unsure. Is the following configuration valid, when communicating rpmsg between R0 and A53?
Any other ideas are welcome!
Device Tree:
&mailbox0_cluster2 {
status = "okay";
mbox_main_r5fss0_core0: mbox-main-r5fss0-core0 {
ti,mbox-rx = <0 0 2>;
ti,mbox-tx = <1 0 2>;
};
};
/* Cluster mode for remoteproc driver set to single-CPU mode */
&main_r5fss0 {
ti,cluster-mode = <2>;
};
&main_r5fss0_core0 {
mboxes = <&mailbox0_cluster2>, <&mbox_main_r5fss0_core0>;
memory-region = <&main_r5fss0_core0_dma_memory_region>,
<&main_r5fss0_core0_memory_region>,
<&main_r5fss0_core0_memory_region_shm>;
};
Information:
At the moment, we are using:
MCU+ SDK Version 09.01.00 (for ti lwip stack)
Industrial SDK Version 09.02.00 (currently not in use)
