Porting the FreeRTOS-Plus-TCP library to MCU nRF52840 "nRF52840 + bg96"

[Lora]

Hello ,

I am working on a project an nRF52840 + quectel BG96 modem. I am porting the freeRTOS cellular interface library for the Nordic platform and mainly the FreeRTOS-Plus-TCP library.

https://www.freertos.org/FreeRTOS-Plus/FreeRTOS_Plus_TCP/Embedded_Ethernet_Porting.html#xNetworkInterfaceInitialise

https://github.com/sifive/Amazon-FreeRTOS/tree/master/libraries/freertos_plus/standard/freertos_plus_tcp/source/portable/NetworkInterface

I would like to know if anyone has managed to port the FreeRTOS-Plus-TCP library to MCU nordic ( nRF5280 kit ) especially the MAC Ethernet driver part, otherwise I tried to look for an ethernet driver for initialization of the ethernet MAC layer. My question: is there a MAC ethernet driver on the nRF52 SDK, if not can I use the lwip library on the sdk_nRF16? I'm a bit lost, any ideas are appreciated. Could you help me please .

Thank you and best regards,

We have not done any efforts to port this on our FreeRTOS port. I cannot see if anyone else have done this before either. Seems like you need to do this yourself if you want to make this port work on nRF.

Hi Nuguru,

Thank you for your feedback.

can I use the lwip driver on the sdk_nRF52 for ethernet hardware initialization to get a network link.

Do you have any advice plz, as I'm a bit lost.

Thank you and best regards,

you can ofcourse use the lwip port we have in the external modules but we have not tested this with freertos, just that you know.

But on the other hand the lwip driver it uses a layer of Nordic's 6lowpan interface to send data to a remote TCP port and that's not really what I'm looking for

yes, unfortunately, that seems true.
