Indirect programming of SPI serial flash PROMs

Posted: 28 Nov 2008     Print Version  Bookmark and Share

Keywords:M25Pxx  PROM  Spartan-3A 

This application note by Xilinx describes the hardware setup, file generation flow, and software flow for programming an STMicroelectronics M25Pxx SPI configuration PROM through the JTAG interface of a Spartan-3A FPGA using iMPACT 9.1.01i. The software flows, including PROM file generation, are also covered.

Similar to the traditional configuration memories, SPI serial flash memories must be loaded with the configuration data. SPI serial flash memories have a single interface for programming, but there are multiple methods to deliver the data to this interface.
