This document introduces the Altera® Serial FlashLoader (SFL) as the first in-system programming solution for Altera serial configuration devices using the JTAG interface. The SFL solution is available with Quartus® II software version 4.1 SP1 and later.
The document describes the Altera Serial FlashLoader (SFL) solution, which allows programming of serial configuration devices (such as EPCS1, EPCS4, EPCS16, EPCS64, and EPCS128) in-system using the JTAG interface. This method uses an FPGA as a bridge between the JTAG interface and the active serial memory interface block.
The SFL solution is available with the Quartus II software version 4.1 SP1 and later, while the SFL megafunction is available with version 6.0 and later.
The document refers to Altera EPCS1, EPCS4, EPCS16, EPCS64, and EPCS128 devices when using the term 'serial configuration device'.
