8 byte alignment

Working with real view compiler for ARM (used by Keil) I ran into a need for 8 byte alignment of the stack. (sprintf with float values did not work otherwise.) To achive this I had to add the following lines in heap_1.c: #if portBYTE_ALIGNMENT == 8     #define heapBYTE_ALIGNMENT_MASK    ( ( size_t ) 0x0007 ) #endif I also made some changes to my port of the OS. In port.c, pxPortInitialiseStack, first lines:     /* Setup the initial stack of the task.  The stack is set exactly as     expected by the portRESTORE_CONTEXT() macro.     8 byte alignment: */     pxTopOfStack = (portSTACK_TYPE *)((long)pxTopOfStack & 0xfffffff8); In portmacro.h: #define portBYTE_ALIGNMENT            8 I’ll send the changes to Richard.

8 byte alignment

Thought that was in there already or was that just 4 byte alilgnmebt?

8 byte alignment

Correct, there was 1, 2 and 4 byte alignment already. No big change! Jokke
