Two jumpers on the 3-pin connectors, J16 and J17 define reset configuration of the board and the way
status reset signals are driven.
Status reset signals are:
DONE_FPGA: the CONF_DONE FPGA configuration status signal
DONE_FPGA_CAP9: indicates the FPGA configuration status to the AT91CAP9 microcontroller (PIO
2.4.1.14 F14: Programming and Configuration
2.4.1.14.1JTAG Programming
Two different JTAG programming chains are implemented on the board:
Stand-alone JTAG chains (default)
Each programmable device (microcontroller and FPGA) has it's own JTAG programming chain. (
“EI11: JTAG and Serial Configuration Interfaces” on page 2-7.
)
– ICE-JTAG chain for AT91CAP9 JTAG programming
– USB-Blaster chain for FPGA JTAG programming
ICE-only JTAG daisy chain
It's possible to use only the ICE-JTAG interface to program microcontroller and FPGA on a unique JTAG
daisy chain. AT91CAP9 is the first device in the daisy chain, FPGA is the second one.
Configuration of the jumper positions must be as shown in the table that follows.
2.4.1.14.2Serial Device Configuration
Three ways can be used to program the FPGA EPCS16 serial device.
Serial device configuration port
The FPGA EPCS16 serial device configuration can be programmed via the EI11 serial device configura-
tion port with Altera USB Blaster probe.
