Other Parts Discussed in Thread: SYSBIOS

Dear experts,

Is there any demo code to use CPSW2G from MCU R5F SYSBIOS? I am using PSDKRA 7.0.

If no, could you please give some idea which code to start with, and which code to refer?

Thanks & Best Regards!

Hi ZM,

Is this PDK or MCAL you are looking for?

Karan,

In fact, my customer wants to run a TCP stack on MCU R5F using CPSW2G.

From my understanding, he should start from a CPSW2G demo application on MCU R5F, then call NDK apis.

But I cannot find any demo application to use CPSW2G from MCU R5F. And also it is hard to find a guide to call NDK API.

They also tried PDK unit test, but failed on MCU R5F. Do you know which case is validated on MCU R5F with CPSW2G?

Thanks & Best Regards!

ZM,

Please refer to http://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/latest/exports/docs/psdk_rtos_auto/docs/user_guide/developer_notes_ethfw.html?highlight=cpsw2g#developing-ethernet-based-applications-with-linux-rtos for guidance on the CPSW2G Ethernet software for RTOS

CPSW LLD is low level driver residing in the PDK. It supports CPSW2G and CPSW9G IPs and provides HAL layer for higher level stacks. EthFw uses CPSW LLD for CPSW9G switch configuration. NIMU (Network Interface Management Unit) is TI NDK abstraction layer connecting CPSW LLD to NDK stack. NIMU library is part of CPSW LLD and enables using CPSW2G and CPSW9G with TI NDK TCP/IP applications

Documentation and source code links are provided on this page.

Specifically for NDK:

pdk/packages/ti/drv/cpsw/examples/cpsw_nimu_example includes an NDK integration example for CPSW2G/9G. Supported core (mcu2_0, mcu1_0, mpu1_0, mcu2_1).

Best regards,

Dave
