lwip documentation for i.MXRT

[nsiegel]

Hi,

I'm looking for the lwip documentation.  I didn't find it in either the SDK or the SDK documentation package.  I'm most interested in the lwip version included with SDK v2.9.0 for iMXRT1170.

Thanks!

Hi, 

you can find the lwip version in the \middleware\lwip\ChangeLogKSDK.txt . There is specified exact branch and SHA which was used for given release. 

e.g :  

2.2.0_rev3
- Ported lwIP 2.2.0.dev (2020-07-07, branch: master, SHA-1: c385f31076b27efb8ee37f00cb5568783a58f299) to KSDK 2.0.0.

see:

Thank you for the link to the other post.  I noticed that post is from 2019, and refers to SDK v2.6.  Which version of lwip is included in SDK v2.9.0 for i.MXRT1170? 

What I'm really after is high level documentation of what's supported by the SDK.   Are there any release notes?  Are TLS, SSL, NTP, RTP/RTSP  supported?

Thanks

Hi,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
To provide the fastest possible support, I'd highly recommend you refer to the post to learn the LwIP stack in the SDK library.
Have a great day,
TIC
