load sketch into SPI flash

5 posts in this topic

Is it possible to load the sketch into SPI flash, along with the .bit file in designlab? (It is possible for microblaze in ISE).

regards.

The sketch is loaded into SPI flash. Once you load a sketch and power cycle the sketch is still in effect.

Interesting...  Thank you jack.

So the bootloader automatically looks into SPI flash in the boot time and loads the software code into the RAM?

Yes, that is how it works for ZPUino. For a regular bit file the FPGA boots from the SPI flash directly.

To be more precise, the FPGA boots the initial ZPUino from SPI flash [FPGA design], it starts, waits for 1 second for serial/usb commands and then loads the user code from SPI flash and executes it.
