5.6.2. JTAG Chain Control DIP Switch
The JTAG chain control DIP switch (SW3) either removes or includes devices in the active JTAG chain.
The SW3 switch select controls the JTAG master/slave select. The DIP switch MSTR switches control the master select. The other 5 pins are bypass pins for the various available JTAG slaves. The following slaves are available and can be bypassed by moving the corresponding bypass switch to the 'ON' position.
Switch 3 Bit | Board Label | Function |
---|---|---|
1 | Arria 10 | ON- Arria10 JTAG Bypass OFF- Arria10 JTAG Enable |
2 | I/O MAX V | ON- MAXV JTAG Bypass OFF- MAXV JTAG Enable |
3 | FMCA | ON- FMCA JTAG Bypass OFF- FMCA JTAG Enable |
4 | FMCB | ON- FMCB JTAG Bypass OFF- FMCB JTAG Enable |
5 | PCIe | ON- PCIe JTAG Bypass OFF- PCIe JTAG Enable |
6 | MSTR[0] | Refer to Table 25 |
7 | MSTR[1] | Refer to Table 25 |
8 | MSTR[2] | Refer to Table 25 |
The MSTR switch settings and their meanings can be seen in the table below.
MSTR2 | MSTR1 | MSTR0 | Modes |
---|---|---|---|
ON | ON | ON | BOOT |
OFF | ON | ON | FMCA JTAG Master |
ON | OFF | ON | FMCB JTAG Master |
ON | ON | OFF | FTRACE JTAG Master |
OFF | OFF | OFF | On-Board USB-Blaster II JTAG Master |
ON | OFF | OFF | System Configuration Mode |
OFF | ON | OFF | GUI Test Mode |
OFF | OFF | ON | Reserved |
The bypass switch settings dictate which slaves are in/out of the chain, but see below for the order if all were enabled in the chain.
- Arria 10
- IO_MAXV
- PCIe
- FMCA
- FMCB
