FreeRTOS + TCP example for IMX RT 1170 EVK

shrinivasnh — Wed, 03 May 2023 07:24:27 GMT

I need to use network stack on my project, but due to some reasons similar to one listed as below link

Using NonCached Memory on i.MXRT - NXP Community

Even after following the solution listed, we are facing similar issues

Can you help me in following

1. FreeRTOS has its own TCP/IP stack

2. Need some demo example which can help me to run Frtos with tcp on USB-RNDIS interface

I was able to get lwip+frtos, but i need frtos+tcp example

Kindly suggest

Hi @shrinivasnh

I understand that you are willing to implement FreeRTOS open source TCP/IP stack instead of LWIP stack, as our lwip_dhcp_usb SDK examples do. Is this correct? If yes:

Available information that I know it may help is in the FreeRTOS documentation ( link from above) and from our AN13940 Connect i.MX RT1060 to USB 4G Module (RNDIS Mode)

Regarding the link you shared Using NonCached Memory on i.MXRT - NXP Community and the issues you mention to face. Are they related to MPU settings? Are the issues the reason why you are looking for a different stack for TCP/IP?

Please kindly correct me if needed and if you got more details on your application let me know.

All the best,

Diego
