NiosV FreeRtos TCP/IP stack

[ser1]

Nios-V Processor Software Developer Handbook mentions support for FreeRTOS.

Is there also some TCP/IP stack ported to FreeRTOS and Tripple Speed Ethernet IP?

Hi,

Greetings and welcome to Intel's forum.

Yes, The Nios V processor tools contains the µC/OS-II RTOS and the µC/TCP-IP software component with the information here for your reference: https://www.intel.com/programmable/technical-pdfs/726952.pdf (Section 5. Nios V Processor - Using the MicroC/TCP-IP Stack)

The design example is also available for the MicroC/TCP-IP porting to Triple Speed Ethernet for the Arria10 device with the steps here: https://www.intel.com/programmable/technical-pdfs/726952.pdf (Section 5.4. MicroC/TCP-IP Example Designs). You may also use your own devkit by following the steps above to obtain the hardware Triple Speed Ethernet design example.

Hope this clear your doubts.

Thank you.

Hi Kelly!

Thanks for the links on the µC/OS-II RTOS and the µC/TCP-IP.

My question is about FreeRTOS. What stack should be used with FreeRTOS?

HI,

The stack to use with RTOS will be the MicroC/TCP-IP stack.

Here are some information and steps on the MicroC/TCP-IP stack: https://www.intel.com/content/www/us/en/docs/programmable/726952/23-1/introduction-03876.html

Hope this clarifies your doubts.

Thank you.

Ok,

So, I guess, there is no TCP/IP stack ported for Nios-V + TSE + FreeRTOS combination.

I think links below might be useful to anyone seeking answer to the same question:

- There is uC TCP/IP stack for uC-OS (Nios-II and Nios-V + TSE): https://github.com/weston-embedded/uC-TCP-IP/tree/develop , unfortunately, looks like development has stopped for uC-OS and uC-TCP-IP, great example for adding TSE support to other stacks.

- There are example designs with niche stack (Nios-II + TSE). At least now, these can be found https://www.intel.com/content/www/us/en/support/programmable/support-resources/design-examples/horizontal/exm-tse-sgdma.html . Niche-stack itself is not recommended by Intel.

- There are some relatively old lwip ports to FreeRTOS (Nios II + TSE), lwip is not recommended by intel:
