FPGA Multiboot - When updating Multiboot image, what erase/program ordering is recommended?


When I try to update the Multiboot image, should I erase/program from the beginning or from the end?


Xilinx recommends avoiding loading Sync words where the follow-up data is corrupt.

When Erasing, the sync words sector must be erased first.
The recommended order is to erase from the beginning to the end of the bitstream.
When programming, the sync words sector must be programmed last.
The recommended order is to program from end to beginning.
