S32K388 lwip with DCache enabled problem

Good Afternoon,

I'm working on a lwip project whose purpose is to run a web server. For this, I'm using FreeRTOS as OS and the MCU S32K388. The RTD version used is S32K3_S32M27x Real-Time Drivers ASR R21-11 Version 5.0.0, the FreeRTOS version used is S32K3 FreeRTOS 11.1.0 version 5.0.0 CD01 and the TCPIP Stack version is S32K3 TCPIP STACK 2.0.0.

The project works as expected but some days ago I decided to emulate an EEPROM in order to save some information inside the NVM, using the Fee module. The thing is that to emulate the EEPROM, I have to initialize the DCache and when I do it, the web server does not works.

I tried to follow step by step this post Re: S32K344/S32K324 TCPIP_STACK Intergration - NXP Community but still not working.

Any help would be appreciated!

Thanks in advance!
