Hello Team
May I ask about LWIP with Freertos based on K5?
When I use Baremetal with LWIP, it is working well.
However, Freertos with LWIP, it is showing like below. I have attached Wireshark log also.
The below is my IDE information and it is showing same result both DS and DP cases with freertos.
Could you check this case?
Thank you.

Hello @lyxye
May I ask about the progress?
Thank you.
Hello @lyxye
Thanks for your supporting.
When I did the test, I saw some abnormal behavior with PBUF...
I'm not sure, but could this be related?
Thank you.
hi Luke_Chun,
We discovered that TX buffers leaked due to race condition between TX thread and ISR in FreeRTOS
Solution: Wrapped EthIf_Transmit() with sys_arch_protect/unprotect to prevent preemption
A patch will be provided in an upcoming release. You can use the following workaround in the meantime.
Best Regards,
