I try to use lwip_mpc5748g demo_app to new a project.The S32 design studio version is 2017.R1. The steps is as follow:
1.Create S32DS Project from lwip_mpc5748g
2.use default parameters to generate PE code;
3.compile the project.
Then there are some compile errors:
1.'configMINIMAL_STACK_SIZE' undeclared (first use in this function) test.c /lwip_mpc5748g/Sources line 400 C/C++ Problem
2.Description Resource Path Location Type

What's the problem?hope for some advice.Thanks.
That error comes from FreeRTOS.
Normally, lwip_mpc5748g comes with FreeRTOS enabled by default.
Could you please check your example from which SDK version?
Hello,
which operating system are you using? I tried the lwip example - and got only couple warnings - no error.
