TM4C1294NCPDT: LWIP porting with CMSIS-RTOS

Part Number: TM4C1294NCPDT

Hello all,

Micro-controller : TM4C1294NCPDT

IP stack : LWIP (1.4.1)

I have used lwip raw api to send tcp and udp packets and it was successfull.

Now I want to write an application which sends UDP packets from different threads using CMSIS-RTOS with lwip(socket API).

So, I was configuring the lwipopts.h, and i enabled NO_SYS as 0, LWIP_SOCKETS as 1 and LWIP_NETCONN as 1.

Enabling this gave a lot of errors from sys.h and sys_arch.h.

I have searched about the use of lwip with OS and i could get only information about lwip being used with FREErtos.

Have anyone tried using Lwip with CMSIS-RTOS. Can anyone give an idea about porting CMSIS-RTOS to be used with lwip?

I know that raw api is meant to be used without an OS, but is there a way that i can make it thread safe?

Thanks in advance.

Hello Sreya,

Unfortunately we have no experience with that RTOS, I personally haven't even heard of it before. If you are looking to use an RTOS, I would recommend using TI-RTOS. That would allow you receive support for this application.

We aren't in position to support 3rd party RTOS solutions, sorry.

Thanks for your response.
So does that mean lwip doesn't support every RTOS?

Hello Sreya,

That's not what I was saying. I imagine LwIP can work with any RTOS, but LwIP is a third party solution and not made by TI, so we cannot offer more than basic support for LwIP, and we cannot help with an RTOS that isn't TI-RTOS even if our MCU is being used. Sorry that we aren't able to help more, but ultimately we are experts of our devices and not necessarily all use cases for them.

FYI there is a wiki for LwIP, maybe you can find something useful there: lwip.wikia.com/.../LwIP_Wiki
