Error information
If writing is interrupted due to cable disconnection during FPGA download, check for messages on the windows of the FPGA
design software and FPGA module configuration tool, and the communication environment, such as the cable connection
status, and then perform the writing operation again.
Precautions
• Be sure to turn off the power to the FPGA module before connecting the JTAG cable. If connected while the power is ON, it
may cause malfunction or failure.
• Write via JTAG in an environment that is not affected by noise. Using it in an environment affected by noise may cause
malfunction or failure.
• When downloading configuration data in JIC format or RPD format, the total number of downloads should be 100000 or
fewer.
• Do not execute FPGA download via JTAG and FPGA download via Ethernet at the same time.
• In CC-Link IE TSN communication mode, an FPGA module that has never been data linked with the master station
operates with the default IP address and subnet mask. Note that this is different from the IP address (1st to 3rd octets) and
subnet mask of the master station, so be careful when setting the connection destination with the FPGA module
configuration tool. ( Page 54 IP address/station number setting switch setting)
• For safety reasons, before starting an FPGA download, assure that the FPGA module is stopped under FPGA control, the
power supply of the external I/O connection partner device is turned off, and the Ethernet connection partner device is
stopped from accessing the FPGA module via SLMP communication.
