Hi,

We saw a major issue on calling wiced_tcp_disconnect with tis context that will lead to system crash.. This can be very easily reproduced on the demo code snip.https_client sample in the SDK.

Best Regards,

Aaron Lee

This has been root caused to a bug in gcc producing an invalid instruction sequence under some circumstances.

Recommended fix is to modify the wiced_toolchain_ARM_GNU.mk and change line 102/103 from "-O3" to "-Os"

Can you please do a test for me - can you build and run in debug mode and see if the issue still happens or not? add "-debug" to the makefile command

Hi,

Enabling the debug on snip.https_client will help but still crashes if you loop the https get. It will crash after few loop.

Was this fixed in 3.1.1? If not what parameter (and line number if possible) needs to fixed in:

wiced_toolchain_ARM_GNU.mk


COMPILER_SPECIFIC_RELEASE_CFLAGS?

Hi

Is this problem solved in SDK 3.1.1? 

I had similar problem in SDK 3.1.1. Web access seem not to be valid.

so if connection is done , and try get another page then it takes long time.

Test env : SDK 3.1.1 + FreeRTOS+LwIP

I changed OS from FreeRTOS to ThreadX, Web access is working well and no problem occured.

So I thought that this is driven from

  - memory usage(management ) difference is from each OS, so some of malloc fail happen.

  - socket count management in http server

  - socket connection timeout

Test env : SDK 3.1.1 + ThreadX+NetX

With changing to ThreadX, all works fine.

Additionally,  ThreadX has some other issues in different function.

Hi Alex,

We use SDK 3.1.1 + ThreadX+NetX setup and so far is working alright.  I suggest to post another thread specific for 3.1.1 with your setup and see how Broadcom response.

Hi  aaron

   it is good to hear that you are all right.

   With 4390, I am doing test with 4390 module  and you can see our module's web.

  It is working well with ThreadX

   http://damosys.com:9990

   It is 4390's EVB and our web in module.

   We are planing our own module with good antenna design.
