Hi,
I have SEED-OMAP L137 board , and the omap L137 's ROM ID is D800K001,it boot from 8bits nandflash.Now, I designed a new board ,It's ROM ID is D800K003, I download Aisgen for D800K003,but the board doesn't work,there is no message from UART2. My new board pass all the test under CCS3.3(NAND,SDRAM etc).Could somebody tell me , why?Is there anything new about D800K003? Hardware has no error.
My boot mode is 8 NANDFlash , not the UART2, so I think 230.4 Kbaud to 115.2kBaud doesn't matter.
I download uboot to SEED-OMAPL137(ROM ID is D800K001) like this(refer to the seed Manual);
1.compile uboot , get u-boot.bin under linux.
2.use raw2coff under AisGEN for D800K001 to convert u-boot.bin. command line is: raw2coff u-boot.out 0xc10800000 u-boot.bin
3. then,open AISgen for D800K001,conver .out to .bin
4.Last, open nandwriter ,download the uboot.
5.power on the board again, uart2 send start message.
the following codes are part of SEED board 's nandwriter .
static Uint32 nandwriter()
{
Uint32 numPagesUBL;
NANDWRITER_Boot gNandBoot;
NAND_InfoHandle hNandInfo;
FILE *fPtr;
Uint8 *ublPtr;
Int32 ublFileSize = 0,ublAllocSize = 0;
Int8 fileName[256];
Int32 i=0;
Int32 uiHeaderLen = 0;//sizeof(NANDWRITER_Boot);
printf( "Starting OMAPL137 NANDWriter.\r\n" );
// Initialize NAND Flash
hNandInfo = NAND_open((Uint32)&NANDStart);
// hNandInfo = NAND_open(0x62000000);
if (hNandInfo == NULL)
{
DEBUG_printString( "\tERROR: NAND Initialization failed.\r\n" );
return E_FAIL;
}
// Read the file from host
fwrite("Enter the AIS binary file Name",1,sizeof("Enter the AIS binary file Name"),stdout);
fflush(stdout);
scanf("%s", fileName);
fflush(stdin);
if (strcmp(fileName,"none") != 0)
{
// Open an File from the hard drive
fPtr = fopen(fileName, "rb");
if(fPtr == NULL)
{
DEBUG_printString("\tERROR: File ");
DEBUG_printString(fileName);
DEBUG_printString(" open failed.\r\n");
return E_FAIL;
}
// Read file size
fseek(fPtr,0,SEEK_END);
//happydog
ublFileSize = ftell(fPtr);
if(ublFileSize == 0)
{
DEBUG_printString("\tERROR: File read failed.. Closing program.\r\n");
fclose (fPtr);
return E_FAIL;
}
ublFileSize += uiHeaderLen;
numPagesUBL = 0;
while ( (numPagesUBL * hNandInfo->dataBytesPerPage) < ublFileSize )
{
numPagesUBL++;
}
//We want to allocate an even number of pages.
ublAllocSize = numPagesUBL * hNandInfo->dataBytesPerPage;
// Setup pointer in RAM
ublPtr = (Uint8 *) UTIL_allocMem(ublAllocSize);
if(ublPtr == NULL) {
DEBUG_printString("\tERROR: Unable to allocate memory sized %d bytes for file read\n", ublAllocSize);
return E_FAIL;
}
for (i=0; i<ublAllocSize; i++)
ublPtr[i]=0x00;
fseek(fPtr,0,SEEK_SET);
if ((ublFileSize-uiHeaderLen) != fread(ublPtr + uiHeaderLen, 1, ublFileSize-uiHeaderLen, fPtr))
{
DEBUG_printString("\tWARNING: File Size mismatch.\r\n");
}
fclose (fPtr);
gNandBoot.magicNum = UBL_MAGIC_SAFE;
gNandBoot.block = DEVICE_NAND_RBL_SEARCH_START_BLOCK;
gNandBoot.page = 0;
gNandBoot.numPage = numPagesUBL;
gNandBoot.entryPoint = 0x800066c0; // This fixed entry point will work with the UBLs
gNandBoot.ldAddress = 0; // This doesn't matter for the UBL
memcpy(ublPtr,(void*)&gNandBoot,uiHeaderLen);
if (LOCAL_writeHeaderAndData(hNandInfo,&gNandBoot,ublPtr) != E_PASS)
{
printf("\tERROR: Write failed.\r\n");
return E_FAIL;
}
}
return E_PASS;
}
now my board's omapl137,its ROM ID is D800K003, How will I do?By the way ,I saw many documents said that , flash dspubl,armubl and uboot, but the SEED omapL137 only flash the uboot, is it OK?
