FPGA Download Function

Writes the created configuration data to the FPGA module.
There are two writing methods, as follows.
• How to write via JTAG ( Page 302 How to write via JTAG)
• How to write via Ethernet ( Page 305 How to write via Ethernet)
Configuration data
Configuration data created in advance with FPGA design software is required to perform an FPGA download.
The file format of the configuration data differs depending on the download method. ( Page 302 How to write via JTAG,
 Page 305 How to write via Ethernet) For how to create configuration data, refer to the following.
Page 140 FPGA Development Procedures
For the procedure for converting from SOF format to JIC format or RPD format, refer to the following.
Page 309 Procedure for conversion from SOF format to JIC format and RPD format
Design security
FPGAs have a design security function as a means of enhancing security.
The design security function encrypts the data using any desired key when generating configuration data.
During configuration when the power is turned on, the configuration data encrypted by the decryption key (AES key) already
written to the FPGA is decrypted and configured.

Operation
■LED status
The status of the FPGA download can be checked by viewing the LED of the FPGA module.
Status of FPGA module
Normal operation
During FPGA download
FPGA download completed
*1 After the FPGA CONF. LED starts flashing due to the download operation, even if the writing is interrupted, such as when the cable has
been disconnected, the FPGA CONF. LED will continue flashing. Even while in the flashing state, the download operation can be
repeated using the FPGA design software or FPGA Module Configuration Tool.
*2 If an error is detected in accessing the configuration ROM during an FPGA download via Ethernet, the ERR.LED lights up. At this time,
a configuration ROM access error (error code: 3A20H) will occur.
*3 If the FPGA download method uses the configuration ROM as the write destination, the FPGA module performs FPGA configuration
after the writing to the configuration ROM is completed. If an error occurs in the FPGA configuration, the FPGA CONF. LED turns off. At
this time, an FPGA configuration error (error code: 3C01H) occurs and the ERR.LED lights up.
■Remote input signals
When the FPGA download starts and the FPGA CONF. LED starts flashing, remote READY (RXB) turns off.
Remote READY (RXB) turns ON when the FPGA configuration is complete.
