When using the New Project wizard with IDE 10.3 and SDK 2.5 the LWIP and FATFS are not available in the middleware section.
Ironically wolfSSL is there, which is kinda hard to use without lwip...
Is this a bug or a management decision?
I saw this comment in another thread
Unfortunately NXP does not have a plan to add the snmp demo into SDK due to the maintenance reasons.
I would suggest you implement it by yourself, please refer to below link.
This is not a bug in the new project wizard. The IDE uses data supplied by the SDK to populate these options, and there appears to be a problem with this the data in the current SDK 2.5 release. I believe an SDK update is being investigated to resolve this.

This is a bug in new project wizard, will be fixed in future release.
The recommended approach if such components are required is to import an example including the component and modify as required.
