<p><b>New page</b></p><div>=== What do the Switches on the SMT101 do? ===<br />
<br />
'''SW1''':<br />
<br />
ON/OFF<br />
<br />
1: Hard/soft reset<br />
<br />
2: BYTE_MODE<br />
<br />
3: FLASH / USB configuration<br />
<br />
4: pxie_rst_n, not used in the code<br />
<br />
<br />
<br />
'''SW2''':<br />
<br />
ON/OFF<br />
<br />
1: PCIS1<br />
<br />
2: PCIS0<br />
<br />
3: bitstream position0/position1<br />
<br />
4: link PCI(e)/USB<br />
<br />
<br />
On the SMT101, the same functionality has been kept as for the SMT100 for switches SW1 and SW2.<br />
<br />
It means that to access the flash from the USB (board being powered through the external power supply connector or the PC104 connector - as the flash section on the board is not powered through the USB link), SW1 and SW2 should be set as follows:<br />
SW1=ON|ON|ON |OFF and<br />
SW2=ON|ON|OFF|OFF.<br />
Two FPGA bitstreams can be stored into the on-board flash memory.<br />
<br />
<br />
Once a bitstream has been stored into flash (implementing a PCI Express interface), the board can boot from the Express bus after a reset. In order to do so, SW1 and SW2 have to be changed as follows:<br />
SW1=ON|ON|ON |OFF and<br />
SW2=ON|ON|ON |ON. (Bitstream 0)<br />
Or<br />
SW1=ON|ON|ON |OFF and<br />
SW2=ON|ON|OFF|ON. (Bitstream 1)<br />
<br />
Note that in the case where only one bitstream is stored into flash, the bitstream selection switch could be ON or OFF.<br />
<br />
<br />
=== What is this bit of the SMT100 / SMT101? ===<br />
<br />
If you have an SMT100 or SMT101, and are wondering what or where a certain part is, you can use the helpful interactive images on the pci104.biz website.<br />
<br />
The images can be found on [http://www.pci104.biz/pci104_ident.php this page]<br />
<br />
=== What is the pin out of the external power connector (JP1)? ===<br />
<br />
The external Power connector (JP1) on the Non-FPGA side of the SMT101 has the following pin out:<br />
<br />
'''Pin 1: +12V''' (nearest the edge of the board)<br />
<br />
'''Pin 2: +5V'''<br />
<br />
'''Pin 3: +3.3V'''<br />
<br />
'''Pin 4: GROUND'''<br />
<br />
'''Pin 5: -12V''' (nearest the edge of the MicroSD socket)<br />
<br />
<br />
The mating connector we use at Sundance is made from:<br />
<br />
'''ERNI 254827''' (Housing)<br />
<br />
'''ERNI 284071''' (Crimps)<br />
<br />
