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.
