Hello!

I’m trying to add FreeRTOS’s TCP/IP source files into a project that uses the Cerebot Mx7ck board with the PIC32MX795F512L chip. I looked through the demos and wasn’t able to find anything related to the PIC32 family of microcontrollers, so I’ve been trying to port FreeRTOS+TCP by following the process described on the FreeRTOS website: https://www.freertos.org/FreeRTOS-Plus/FreeRTOS_Plus_TCP/Embedded_Ethernet_Porting.html#NetworkBufferDescriptor_t

I was wondering if anyone has successfully done this before? So far the project builds with all the TCP/IP files included, but I’m struggling to figure out all the pieces needed to get the Ethernet MAC driver setup and I’d appreciate any pointers.

Thanks!

Yes sure there is a driver for FreeRTOS+TCP for the PIC32, in the official repo of AWS/FreeRTOS.

Here is a demo

It uses this +TCP driver, which runs on a PIC32MZEF board. I don’t now how compatible that is with your Cerebot Mx7ck board. Also look at the type of PHY used.

If you want to use the LAN, please define PIC32_USE_ETHERNET globally. If not defined, the WiFi driver will be included.

If you have more questions, feel free to ask in this post.

Hi,
'm using freeRTOS+tcp/ip on pic32mzef
im trying to implement the ethernet module with LAN8720A
my actual problem is when i send a data on the client, i can’t find it on the server.
im using simple client and server tasks.
