I am testing a TM4C129 connected to an CY7C1010DV33 sram. I am using ccs6.01, Stellars ICDI.
I write the code listed below:
#define ERAM(x) HWREG(SRAM16_MAPPING_ADDRESS+SRAM16_SECTOR_ADDRESS+x)
for ( i=0; i< 0x10000; i++ )
{
// ERAM(i*4) = i;
}
//check
for ( i=0; i< 0x10000; i++ )
{
data = ERAM(i*4);
if ( data != (unsigned int)i )
{
LED1_ON;
//break;
}
}
I tested in ICDI debug mode and stand alone mode, the result are all sucsess.
I write another code.
add the code below in .cmd file.
ERAM (RWX) : origin = 0x60080000, length = 0x00040000
esram : > ERAM
the code is in main.c file
#pragma DATA_SECTION(eram_data, "esram");
unsigned int eram_data[0x10000];
#define SIZE 0x100
for ( i=0; i< SIZE; i++ )
{
eram_data[i] = i+1;
}
//check
for ( i=0; i< SIZE; i++ )
{
data = eram_data[i];
if ( data != i+1 )
{
LED1_ON; //ON
break;
}
}
I run it in ICDI debug mode, the MCU run into FaultISR(),The hard fault handler.
Who can help me? Thanks very much!
