I am using Spectrum digital EVMDM6446 (DaVinci EVM) and Spectrum digital XDS560v2 LC Traveller Emulator and Code Composer Studio 5..5.0 and using SanDisk compact flash ultra II (4.0 GB). I am trying to run the spectrum sample code "cf" which is given in spectrum digital Inc website support page (http://c6000.spectrumdigital.com/davincievm/revf/files/davincievm.zip ). do I need to make any changes in the code? card is detecting in function Int16 cf_card_detect( ).
I am trying to read the device ID in :
ATA_readId( ( Uint32 )id );
/* Check for valid identifier */
printf( " CF Identifier: 0x%x\n", ( id[0] << 8 ) + id[1] );
if ( ! ( ( id[0] == 0x8A ) && ( id[1] == 0x84 ) ) )
{
printf( " Invalid CF identifier found\n" );
return 1;
}
and reading only 0x84 and instead 0x8A I am reading 0x00. Not able to run ata_addr32() test too. in address test when I read PRI_ATA_DATA16 value I am getting DDR address (ie in the range 0x08000000). I have mot made any change in the sample code. whats wrong?
Refer Code: Sample code attached, same code and supporting files are given in davincievm.zip folder.
download davincievm.zip folder from http://c6000.spectrumdigital.com/davincievm/revf/)
