web_net_server_nvm_mpfs演示中的错误

我使用的是和声V2.05、XC32 1.44和MPLAB X 4.05，带有Microchip启动器套件、PIC32 MZ（EF）和密码。我可以在没有HTTP和HTTPS版本的HW加速器的情况下编译和执行和声演示（WebSythNETServer NVMMMPFS）。在该演示中使用了WOLFSSL第三方库。当我在MHC中选择HW加速器（2个位置）并运行HTTPS服务器时，程序运行5-10秒，然后挂起。来自Firefox的消息显示“执行TLS握手到192.168100.115…”。这个bug最有可能的地方是WOLFSSL库，以及它是如何与硬件加密进行交互的。我已经询问WOLFSSL帮助找到这个bug，如果他们发现了什么，我会在这里发布他们的发现。还有其他的可能性——bug可能是和谐的，或者是HW加速器本身。所有这些可能性对于我来说都是非常困难的，因为我不知道在框架中去哪里——可能在表示层，但是在哪里？由于在演示示例中存在错误，也许Microchip可以找到bug。我已经联系了WOLSL，并且他们在这个问题上提供了极好的支持。稍后我会在这个帖子上重新发布回复。

    I am using HARMony v2.05, XC32 1.44 and MPLAB X 4.05 with a Microchip starter kit, PIC32MZ (EF) with Crypto.

I can compile and execute the Harmony demo (web_net_server_nvm_mpfs) without the HW accelerator for both the http and https versions. The wolfSSL third party library is used in that demo. When I select the HW accelerator in MHC (2 places) and run the https server, the program runs for 5-10 sec and then hangs. A message from Firefox shows “Performing a TLS handshake to 192.168.100.115…”.

The most likely place for this bug is the wolfSSL library and how it interacts with the hardware crypto. I have asked wolfSSL for help finding this bug and I will post their findings here if they find something.

There are other possibilities -- the bug could be in Harmony or in the HW accelerator itself. All of these possibilities are extremely difficult for me to debug because I have no idea where to look in the framework -- probably in the presentation layer, but where? Since the error exists in the demo example, maybe Microchip could find the bug.

I have contacted wolSSL and they have provided excellent support on this issue.  I will repost the responses later on this thread.
