TMS570LS3137: How BANK7 flash writes data with offset

Part Number: TMS570LS3137

Hi team,

Here's an issue from the customer may need your help:

Normal fee erase, read and write is all good.  The customer would like to know how to write with offsets. The flash function is described in the manual as writing data from the start address of block.

If each block defines 64 bytes, how do customer write 128 bytes of data and write from this address at offset 0x100?

Could you help check this case? Thanks.

Best Regards,

Cherry

    Hi Cherry,

    If the block size is 64 bytes, only the first 64 bytes of data of your data array (128 bytes) are written to the block. The starting address of the block is calculated by the FEE driver. 

    The FEE data write APIs don't accept the address offset.
