Compiler/TMS570LS0432: FEE example in HalCoGen could not change registers of FEE

Hello Xinyu,

Please use memory browser in CCS to check the data in FEE. The starting address of FEE (bank 7) is 0xf0200000.

The HALCoGen provides a example code to read/write the FEE. The example write 1 block data (8 bytes: 01,02,03,04,05,06,07) to FEE.

The first 24 bytes (8 bytes*3) are virtual sector header, the next 8 bytes (0xF0200018, and 0xF020001C) are reserved.

The following 24 bytes (0xF0200020...0xF0200034) are data block header. The block data is just after the data block header: 0xF0200038, 0xF020003C.

Hi Xinyu,

The test Writes, Reads and then Formats at last hence you cannot see any data if you look after Format function has been executed..

I would recommend you to keep breakpoint at TI_Fee_InvalidateBlock(BlockNumber); ( Before executing this function). And then look at the memory window.

    /* Read the block with unknown length */
     BlockOffset = 0;
     Length = 0xFFFF;
     oResult=TI_Fee_Read(BlockNumber,BlockOffset,Read_Ptr,Length);
     do
     {
         TI_Fee_MainFunction();
         delay();
         Status=TI_Fee_GetStatus(0);
     }
    while(Status!=IDLE);

    /* Invalidate a written block  */
    TI_Fee_InvalidateBlock(BlockNumber); --> KEEP BREAKPOINT HERE
    do
    {
        TI_Fee_MainFunction();
        delay();
        Status=TI_Fee_GetStatus(0);
    }
    while(Status!=IDLE);

    /* Format bank 7 */
    TI_Fee_Format(0xA5A5A5A5U);

    while(1);
