MIMXRT1040 - lwip example remapping RAM issue

Hi,

I'm working on the lwip_ipv4_ipv6_echo_freertos example for my MIMXRT1040 EVK, I'm trying to implement a TCP server on my final application.

Looking at the RAM occupation, the example takes a large amount of RAM_DTC that is the main ram region.

In my final application I'll use the RAM_OC as main one, therefore I tried to exchange the RAM_DTC with the RAM_OC in this example. This is how I set up the example:

After this, the RAM_DTC is empty and the RAM_OC is busy as expected:

My problem is here, if I launch the application it stucks (I'm not able to locate where) or during the socket creation or just after that.

So, what am I missing on it? What's wrong on this?

Thank you in advance

Riccardo
