Hi iBond,
Thanks for writing to the forum.
Just wanted to add a few more things.
FreeRTOS-Plus-TCP is a scalable, open source and thread safe TCP/IP stack for FreeRTOS maintained by Amazon Web Services.
The stack is misra compliant, unit tested, CBMC proofed and Protocol Tested for IPv4 using the Maxwell Pro Tester.
You can refer to a similar discussion in this thread FreeRTOS-plus-tcp-vs-lwip
We do have a driver for NXP1060. You can use this as reference for 1170 driver and we will be more than happy to guide you in the same.
