Flash Memory
The Pico
The Flash ROM’s address bus can be controlled by either the TurboLoader or the FPGA (but not both). During
The Flash ROM has a simple, open file system which allows the user to store FPGA images, ELF binary files, or other data. The primary image is used to boot the FPGA initially, and the backup image is only invoked if the primary image fails to load correctly. Executable files are in ELF format and are loaded by a loader within the secondary image. The primary image will either load the secondary image or pause for the PC to access and manage the file system.
