Installation
The minimum system requirements needed to run a SMT358 on a PC is a C4x TIM-
based carrier board and a C4x or C6x TIM with at least a Transmit Comm-Port
(Comm-Port 0,1 or 2) at Reset.
The goal is to connect one of the processors Comm-Port to Comm-Port 3 of the
SMT358.
Follow these steps to install the SMT358 module on a Host system:
1. Remove the carrier board from the host system.
2. Place the SMT358 module into one of the TIM sites on the carrier board.
3. Make sure the that the board is firmly seated, then provide the 3.3V to the board
by screwing the SMT358 on the two main mounting holes with the bolts and
screws provided with the board.
4. Fit the processor-based board on the carrier board. To do so, please follow the
installation procedure of that specific board. In the case of a SMT320 carrier
board, the C4x or C6x board MUST be placed on the first TIM slot (TIM slot 0) of
the SMT320.
5. Connect at least Comm-Port 3 of the SMT358 to one of the transmit Comm-Port
(at Reset) available on the Processor-based board.
6. Connect the SDB links as well if required by your application.
7. Replace the carrier board in the host system.
Configuration
The FPGA configuration is done by a software routine running on a host, ‘C6x or
‘C4x processor that downloads a bitstream to the Virtex/E via the CPLD using
Comm-Port 3(on the SMT358). After configuration, the CPLD gives the hand to the
FPGA, which becomes the owner of Comm-Port 3.
The CPLD does the handshake with the Comm-Port and communicates with the
FPGA as well.
The following description is referring to Figure 7.
Hardware Sequence of events
At power-up.
1) The CPLD polls Comm-Port 3 until it receives the keyword 0xBCBCBCBC.
