xfwr
(xilinx fpga data write)
Function
This command writes peripheral circuit data to the FPGA on the standard peripheral circuit board
inserted in the ICE.
Format
>xfwr <file name> ;{H | S} [;N]
↵
(direct input mode)
<file name>: FPGA data file (.mot: Motorola S, .mcs: Intel HEX)
H:
Load Intel HEX file
S:
Load Motorola S file
N:
Skip erasing before writing data
Examples
>xfwr ..\ice\fpga\c88xxx.mot ;S
↵
>
In this example, the main FPGA is erased and then data in the c88xxx.mot file (Motorola S format) is
written to it.
>xfwr ..\ice\fpga\c88xxx.mot ;S ;N
↵
>
In this example, erasing before writing is skipped. However, the main FPGA must be erased before-
hand.
Notes
• Use the file provided by Seiko Epson as the data to be written without modifying the contents. Also
the file extension cannot be changed as it is .mot (Motorola S) or .mcs (Intel HEX). Specifying an
illegal file results in an error and data cannot be written.
• The N option can be specified when the FPGA has been erased completely using the xfer command.
When writing data to the FPGA that has not been erased, do not specify the N option.
• A dialog box appears to show the progress while executing. To abort execution, click the [Cancel]
button on the dialog box or press the [ESC] key. In this case, the standard peripheral circuit board
cannot be used until the FPGA is erased and reprogrammed.
• Process time including erase is about TBD minutes (max.).
