Re: Combinable task with port select causes ET_ILLEGAL_PC

Hi MyKeys,

I'm not able to reproduce this exception on my machine with the given code.
What version of the tools (xTimeComposer) are you using?

Re: FreeRTOS and xCORE-200 eXplorerKIT

Hi Tobias,

In your port you define the byte alignment as 4 here.

If you change this to 8, it might resolve this issue.

Kind Regards,
Jake

Although many of our products are focused on audio applications, the xCore itself is a general purpose microcontroller.

Re: lwIP issue with remote close of persistent TCP connection

Hi akp, I have been able to reproduce your issue. It comes from our lib_xtcp wrapper around LWIP. We are not correctly handling a LWIP_EVENT_RECV event with a NULL pbuffer. This should be treated as a disconnect event, and forwarded to the application as a XTCP_CLOSED event. This will be corrected i...
