Hi  grsr

After apply the patch from below link

https://community.cypress.com/thread/35745

I have chance to get EAP-TLS work.

But I found the join_ent fails after leave_ent.

It seems not reliable...

Can you check the issue?

With FreeRTOS build:

> join_ent LAB-WPA2-ENT eap_tls bob hello eap mschapv2 wpa2

Joining : LAB-WPA2-ENT

Successfully joined : LAB-WPA2-ENT

IPv4 Network ready IP: 192.168.1.111

Successfully retrieved the session information 0

> leave_ent

leave test: ok

> join_ent LAB-WPA2-ENT eap_tls bob hello eap mschapv2 wpa2

Joining : LAB-WPA2-ENT

There seems to be an imbalance in memory allocation and deallocation after each join_ent and leave_ent. The net total allocated space would increase after each join_ent-leave_ent. It probably could cause a memory leak which means that even join is not expected to work after the error. We will check further to find the issue.

If this statement is true, it means memory leak.

However, I feel it's not related to memory leak...

It looks like if join_ent fails it will not work any more until reboot the device.

Maybe you can write a simple test code to repeat testing

join_ent && join_leave to ensure it is stable for use.
