Nucleo-F439ZI FreeRTOS + TCP always returns a byte count of 0xfffffff4

Hi @sensor_guru,
The value 0xfffffff4 represents -pdFREERTOS_ERRNO_ENOMEM , which prvRECVWait returns when unable to allocate memory for the TCP stream buffer. For helpful advice on this issue, please see: FreeRTOS TCP/IP pdFREERTOS_ERRNO_ENOMEM (Nucleo-F767Zi).

Thank you.
