Generate SB file for FlexSPI NAND image programming

For FlexSPI NAND boot, the IVT offset is always 0x400. However, to reduce effort in calculating the start address for each firmware region, the Flashloader supports programming the FlexSPI NAND boot image to corresponding firmware region in block granularity. So, the bootable image without “_nopadding” suffix will be used.

Generate SB file for FlexSPI NAND image programming

In general, a BD file for FlexSPI NAND image programming consists of 4 steps.

1. The bootable image file path is provided in sources block.

2. Enable FlexSPI NAND access using FlexSPI NAND Configuration Option block.

3. Erase SPI NAND device as needed.

4. Program boot image binary into Serial NAND via FlexSPI module.
