Hi,

I am porting the CC3000 to LPC4337, everything is working if I disable the debugging or I remove all the DEBUGOUT macro from the code otherwise I am getting a HardFault. I am using FREERTOS. What can be the problem.

I don't know what DEBUGOUT does. However, I would start by looking at your stack usage. If you are using FreeRTOS, every task will have a stack, and maybe the use of this macro increases the stack usage, so that it blows the stack on starts overwriting other memory.

A FAQ was just added - minutes ago - for DEBUG* function support in LPCOpen (this is LPCOpen?). http://www.lpcware.com/content/faq/lpcopen-debug-inputoutput-support

I would guess your trying to use the DEBUGOUT function and the UART or device used in that function is not correctly setup. You may need to call DEBUGINIT() if you aren't calling Board_Init().
I hope the FAQ will help.

There was a problem with the stack size, after I increased it is working
