Programming SPI flash with FlashAndBootUtils_2.40

Hi Sebastien,

The error seems to be you have wrongly modified the SFH tool source code and please check & review.

Have you modified appropriate SPI bus not and CS signal in SFH tool source code ?

I hope you have correctly , that why you are able to flash successfully without any errors (ie you able to access the SPI 

Could you please list the changes and files name.

Did you modified other than mentioned in below TI wiki ?

http://processors.wiki.ti.com/index.php/Serial_Boot_and_Flash_Loading_Utility_for_OMAP-L138#Modifications_for_Custom_Boards

I changed structure hDEVICE_SPI_config with different manner.

Please explain bit or provide your changes.

No, about spi flash, I've just modified device_spi.c on stucture DEVICE_SPI_params (not DEVICE_SPI_config : sorry I made an errror) like this :

const SPI_MEM_ParamsObj DEVICE_SPI_MEM_params =
{
  SPI_MEM_TYPE_FLASH,
  24,                     // addrWidth
  256,                    // pageSize
  #ifdef AM1810
  4096,                   // sectorSize
  #else
  0,                   // sectorSize
  #endif
  64*1024,                // blockSize
  4*1024*1024 /*8*1024*1024 */            // memorySize          
};

Hi Sebastien,

Please ensure that you have referred the SPI data sheet and applied appropriate changes (width & size) "device_spi.c"

Could you revert back the changes in this file and try it.

Hi,

In fact, I receive 0xFF (from SPIBUF register) after each writing byte (to SPIDAT1 register) to flash.

But I don't know why?

See :

Uint32 SPI_xferBytes(SPI_InfoHandle hSPIInfo, Uint32 numBytes, Uint8 *spiBuf )
{
  VUint32 *spiTxReg;
  Uint32  i;
 
  DEVICE_SPIRegs *SPI = (DEVICE_SPIRegs *) hSPIInfo->regs;

  spiTxReg = &(SPI->SPIDAT[DEVICE_SPI_DATOFFSET]);

  // Clear any overrun conditions
  if (SPI->SPIFLG & SPI_SPIFLG_OVRNINTFLG)
  {
    spiBuf[0] = (SPI->SPIBUF);
    SPI->SPIFLG &= SPI_SPIFLG_OVRNINTFLG;  
  }
 
  // Write output data
  for (i=0; i< numBytes; i++)
  {
    // Wait for transmit ready
    while (!(SPI->SPIFLG & SPI_SPIFLG_TXINTFLAG));  
 
    // Transmit data
    *spiTxReg = spiBuf[i];
    
    while (!(SPI->SPIFLG & SPI_SPIFLG_RXINTFLAG));
    
    spiBuf[i] = (SPI->SPIBUF);
  }

  return E_PASS;
}
