Hi
I want to boot c28 by using "C-Boot ROM MTOC IPC Commands" referenced form "Concerto F28M35x TRM - 6.6.9 "
So I make code m3 side that below add.
----------------------------------------------------------------------------------------------------------------------------------------------------------
... some intialize code first
// Define Local Variables
unsigned short ErrorCount = 0;
unsigned short usWWord16;
unsigned short *pWord16;
unsigned long ulWWord32;
unsigned long *pWord32;
unsigned short usRWord16;
unsigned long ulRWord32;
unsigned long *pulMsgRam;
unsigned long ulAddress=0;
unsigned int i,j,k,m,n;
unsigned char *pc;
ErrorFlag = 0;
usWWord16 = 0x1234;
ulWWord32 = 0xABCD5678;
usRWord16 = 0;
ulRWord32 = 0;
//-------------------------------------------------------------------------------------------------------
RAMControlInitM1MsgRam();// defined ram.h
RAMControlInitL0L3Ram();
//-------------------------------------------------------------------------------------------------------
UART_printf("sizeof(bootloader_c28)= %d\n\n",sizeof(bootloader_c28));
ulAddress=0x00;
for(i=0,k=0; i<(sizeof(bootloader_c28)/2); ++i,++ulAddress, k+=2)
{
pWord16=&bootloader_c28[k];
IPCLiteMtoCDataWrite(IPC_FLAG1, ulAddress,(unsigned long)(*pWord16), IPC_LENGTH_16_BITS, IPC_FLAG32);
UART_printf("IPCLiteMtoCDataWrite: 0x%x = \t0x%x\n",ulAddress,(*pWord16));
//SimpleDelay();
while (IPCLiteMtoCGetResult(&usRWord16, IPC_LENGTH_16_BITS, IPC_FLAG32) != STATUS_PASS)
{
}
if ((*pWord16) != usRWord16)
{
ErrorCount++;
UART_printf("\tError #1\n");
}
UART_printf("\tIPCLiteMtoCGetResult: \t0x%x\n",usRWord16);
usRWord16 = 0;
UART_printf("IPCLiteMtoCDataRead: 0x%x\n",ulAddress);
while (IPCLiteMtoCDataRead(IPC_FLAG1, ulAddress, IPC_LENGTH_16_BITS, IPC_FLAG32) != STATUS_PASS)
{
}
// Result of Read will be read into usRWord16 variable.
while (IPCLiteMtoCGetResult(&usRWord16,IPC_LENGTH_16_BITS, IPC_FLAG32) != STATUS_PASS)
{
}
if ((*pWord16) != usRWord16)
{
ErrorCount++;
UART_printf("\tError #2\n");
}
UART_printf("\tIPCLiteMtoCGetResult: \t0x%x\n\n",usRWord16);
SimpleDelay();
}

Question
1. Why the writed value is different at adress 0x04, 0x06, 0x07 ?
My code is really wirte c28 ram adress 0x00000 ?
2. Why reboot at adress 0x2e ?
Thank you for reading and i really need your help!
