Programming a development board EPLD
This chapter describes the host utility
epldprog
that enables electronically programmable
logic devices (EPLDs) to be programmed. ST development boards may have several EPLDs
and these can be updated or programmed remotely.
6.1
Connection for EPLD programming
Note:
Many ST development platforms consist of more than one board, for example, a core
processor board and a peripheral board. The ST Micro Connect 2
must
connect to the
physical board on which the EPLDs reside. This information is given in the board datasheet.
There are two different methods of connecting the ST Micro Connect 2 to a board when
programming the EPLDs. One uses a direct LVDS connection (not Type F) on the relevant
board, the other uses the STMC Type A or Type H I/O convertor. (See the
ST
system-on-chip (SoC) debug interfaces technical note
(8339250) for details of the
connectors.)
Figure 4
and
Figure 5
use the HD_GEN_MB
peripheral
board as an example
to show connectivity.
epldprog
is provided for both Windows and Linux hosts and supports both methods of
programming EPLDs. It operates on Altera Jam byte-code (
.jbc
) files and provides
information, program and verify operations. The
epldprog
command line is described in
Section 6.2 on page 34
.
Direct connection
The ST Micro Connect 2 is connected directly to the LVDS port on the board by using an
LVDS cable, see
Figure 4
.
