AM6442: 'git apply NoRTOS_ICSSG0_patch.patch' patch failed, why?

Hi Song Zhijian,

Thanks for your query.

May be because you are working on mcu_plus_sdk_am64x_08_06_00_43 not mcu_plus_sdk_am64x_08_06_00_45?

Some permission issues?

Are you able to create any other patch and apply on your local setup?

Regards

Hi Ashwani,

    Thanks for your reply.   

    I could not find the version of SDK8.6.0.45 from CCS.

    Actually, I am finding a demo of ICSSG0 on AM6442, any other SDK version will be OK. Maybe you can help me solve another problem about ICSSG0.

    My board use ICSSG0-1/ISCCG0-2/ICSSG1-1/CPSW-RGMII2 on A53 core with freeRTOS system， and the CPSW and ICSSG1-1 have been

successfully pinged OK, but ICSSG0-1 and ICSSG0-2 are pinged failed.

    And I find a Application Note "Five Ethernet Port Enablement on AM64x and AM243x"（spradh8.pdf) .

    Chapter 4.1 in spradh8.pdf, refer to github.com/.../ README.md, under ubuntu22.04 , I download mcu_plus_sdk and generate AM64x libs successfully.

     However, when building make -s -C test/networking/lwip/enet_icssg_tcpserver/am64x-evm/system_cpsw_icssg, an error is reported.

For this, you can refer AM243x MCU+ SDK: Ethernet PRU_ICSSG instance-0 (PRU_ICSSG0) USAGE GUIDE (ti.com)

Currently, we have not added ethernet support for A53(RTOS).

ICSSG0-1/ISCCG0-2/ICSSG1-1/CPSW-RGMII2

All 4 ports are in RGMII mode?

Please use SysConfig (ti.com) tool to check the feasibility.

Can you try importing example with CCS?

1. For this, you can refer AM243x MCU+ SDK: Ethernet PRU_ICSSG instance-0 (PRU_ICSSG0) USAGE GUIDE (ti.com)
The AM64x EVM do not use ICSSG0, so I can not check if it works.  And I porting the codes to my board，but ping failed.

2. Currently, we have not added ethernet support for A53(RTOS).
I have porting the ICSSG & CPSW driver from R5 to A53, but ICSSG0 ping failed.

3. All 4 ports are in RGMII mode?

Yes, the  4 ports can works on another kind of  RTOS, I am trying to porting it to freeRTOS, the hardware is OK.

I am wondering if some resources of ICSSG0/ICSSG1 and CPSW are conflicting, such as PKTDMA configuration, but I have not found the specific problem. That is why I am trying to build the "Five Ethernet Port Enablement on AM64x and AM243x" demo.

4. Can you try importing example with CCS?

I have tried this method, it failes too.

It seems that the error reported using CCS is the same as the error reported using makefile.
