#define FOR_ADDRESS for( address.p8 = (uint8 *) BYPASS_DATA_CACHE( SRAM_BASE ); address.p8 < (uint8 *) BYPASS_DATA_CACHE( SRAM_BASE ) + SRAM_SPAN; address.p8++ )
#define DATA (address.byte[2] + address.byte[1] + address.byte[0])
static void fail( void );
///////////////////////////////////////////////////////////////////////////////
void self_test( void )
{
u32_t address;
FOR_ADDRESS
*address.p8 = DATA;
FOR_ADDRESS
if( *address.p8 != (uint8) DATA )
fail();
. . .
The first for loop completes. The Nios II Eclipse debugger "Resume", "Step Into", "Step Over", and "Step Return" buttons stop being selectable when I single step through the first iteration of the second for loop. The Nios II exhibits the same behavior when executing without the debugger.
I haven't skipped the selftest to see if the rest of the program executes successfully since the program after selftest is loaded to that portion of sram and jumped to. I'll try that.
Would installing the patch described in Article ID: 000080509, "FATAL: Cannot generate IP in a Windows environment!" (Bug ID: 14010725090) fix my issue?
