how void avoid multiple definition of `file__404_html';

[zhangzhixing]

when i compiling the S32K366 programm wiht LWIP，there are errors. It appears that the following codes caused the errors.

#define HTTPD_FSDATA_FILE "fsdata.c" 

........

#include HTTPD_FSDATA_FILE

how to void the errors.

the S32DS 3.6 broblem message as below：

Hello @zhangzhixing,

Thanks for reaching out to us. Checking the release notes for the lwip package we offer, I notice that the S32K366 is not in the supported product list, therefore we cannot help you much in the porting, please consider that doing it by yourself can be quite time a consuming and difficult task, and we cannot ensure it works.

If you are searching for a low cost alternative solution to use lwip I can recommend you the FRDM-MCXN947, if you require an automotive chip, please consider the S32K148EVB.

I apologize for the inconveniences.

Best regards

I'm currently using the S32K396 MCU with a raw TCP client implementation, which works fine. However, my module supplier requires me to switch to lwIP with FreeRTOS.

After importing the 'lwip_FreeRTOS_s32k396' example project and flashing it to my K396 board, the program enters the vPortEnterCritical() function when executing prvPortStartFirstTask(). How can I resolve this issue

Hello @zhangzhixing,

Please open a create post  in the S32K community. Since you already selected an accepted solution I won't receive proper notification on the updates in this post.

Please include the following in your new post:

S32DS version

RTD version

lwip version

FreeRTOS version

NXP board name or specify that you are using a custom board.

If you have done any modifications to the example.

For now, it would seems as if you are entering the vPortEnterCritical() function from an interrupt, and you should be using vPortEnterCritical_FromISR() instead. If you are not entering from an interrupt, please specify that in your new post.

Thanks!
