TDA4VM: EthFw Server and Remote Client can not ping each other

Hi,

I found that i can't ping Remote Client(MCU2_1) in A72 Core

Because that would mean that you are trying to ping internally through the SoC, it's not supported right now. It would require A72, R5F to act as independent MAC entities.

But when i try to ping A72 Core and MCU2_1 through MAC Port 3, i can access both of them

Yes, as explained above, an external entity would be able to reach these MAC addresses.

When would it be supported?  i want to use socket to achieve the communication between  R5F cores and  A72. Is it possible to put Remote Client to MCU3_0 and MCU3_1? Currently i only place the Remote Client to MCU2_1.

Thanks,

I will check and get back to you.

Yes, it's possible but the application would require changes. Here is a list of steps 

1. EthFw – update autosarEthDriverRemoteCoreId in EthFw_initRemoteConfig()

2. Update own proc ID

3. Edit MPU configuration to add mcu3_0 IPC region

Can you use MCUSW virtual client application ? The steps for migration are more detailed there

Thanks for your suggestion, i will check the MCUSW virtual client.

I want to double check that can i put the Remote Client to the cores at the same time ( MCU2_1 & MCU3_0 & MCU3_1)?

When i try to add to both MCU2_1 and MCU3_0 and i got the following error log:

[MCU2_0] 4.138668 s: Function:CpswProxyServer_attachExtHandlerCb,HostId:4,CpswType:6

Could you help me?

Support for inter-core communication will be enabled in SDK 8.1 (end of 2021)

For porting MCUSW app to another core, can you check this thread ?

Hi Vineet,

The Max CPSW9G's DMA TX count is 8 and the code is shown below:

./pdk_jacinto_07_01_05_14/packages/ti/drv/enet/soc/j7x/j721e/enet_soc.c line: 507

.txChCount = CSL_PSILCFG_NAVSS_MAIN_CPSW9_PSILD_THREAD_CNT,

But the MCU2_0's core has consumed 4 TX channel and the code is shown below:

Thanks,

hutian
