XC3SPROG(1) General Commands Manual XC3SPROG(1) NAME xc3sprog - JTAG programming utility for Xilinx FPGAs and PROMs SYNOPSIS xc3sprog -c cable [options] file1spec [file2spec ...] xc3sprog -c cable [options] -j DESCRIPTION xc3sprog is a command-line tool for programming FPGAs, microcontrollers and PROMs via JTAG. In a typical application, xc3sprog reads a .BIT file generated by an FPGA design tool, and programs it into the PROM chip on an FPGA board for per- sistent storage or the configuration RAM of a FPGA for temporary storage. For other use cases, see the section EXAMPLES below. As its name indicates, xc3sprog was originally designed for Xilinx Spar- tan-3 FPGAs. However, it has been extended to handle several other types of devices including Xilinx FPGAs, CPLDs, XCF flash PROMs, Atmel AVRs and SPI flash chips. xc3sprog supports several JTAG cables, including parallel port cables and USB programmers. OPTIONS -c cable Specify the type of JTAG cable. The specified type, cable refers to a label in the cable database. Common cable types are pp (parallel port cable), xpc (Xilinx USB programmer), and ftdi (FTDI-based USB programmer). -j Detect the JTAG chain and print a list of attached devices. This is the default if no other action is specified. -p val[,val,...] Use device at JTAG chain position val, default is position 0, the device connected to the TDO pin of the JTAG cable. Use this option to select a device from a multi-device JTAG chain. If multiple chain positions are specified, the data file will be split, programming the first part of the file into the first speci- fied device and so on. This is useful for boards which a chain of multiple XCF chips to configure a single FPGA. -Tn Test the JTAG chain n times. When running in ISF mode, test the SPI connection. If n is not specified, the default is to test 10000 times. If n = 0, keep testing forever. -J freq Run at the specified JTAG clock frequency (freq in Hz). If not specified, or if freq = 0, the default is to run at the maximum fre- quency supported by the cable. Currently only supported for FTDI-based cables. -e Erase the entire device. -I[file] Work in ISF mode to program an internal serial flash memory. The flash memory is attached to the primary JTAG target, but not di- rectly accessible via the JTAG chain. The primary JTAG target is used as a proxy to forward SPI transactions to the flash memory. If file is specified, start by programming the specified bitfile into the primary JTAG target (typically an FPGA). -R Send a reconfiguration command to the target device (XCV, XCF, XCFP for reconfiguration of the connected FPGA device or XC3S, XC6S, XC2V direct) -m mapdir Search for XC2C map files in the specified directory. Map files are required to handle JEDEC files during CPLD programming. If not specified, defaults to the value of $XC_MAPDIR. -d /dev/parportN Specify the parallel port device to be used. If not specified, de- faults to the value of $XCPORT or /dev/parport0. Only used for cable type pp. -s serialnum Use the USB device with the specified serial number string. Needed if several adapters of the same type are connected at the same time. -L Use libFTD2XX instead of libftdi to access FTDI-based cables. -D Dump the device database and cable database to files devlist.txt and cablelist.txt in the current directory. If a file already exists, xc3sprog tries to generate a unique name by appending an increasing number. -X opt[,opt...] Set configuration mode for XCFnnP PROM devices. Configuration from XCFnnP PROM may be done in several modes, depending on the wiring between XCFnnP and FPGA. By default, xc3sprog prepares XCFnnP de- vices for slave serial mode (FPGA running in master serial mode). To override the defaults, specify a comma-separated list of options. The following options are accepted: master XCFnnP is master (FPGA is slave) slave XCFnnP is slave (FPGA is master, this is default) parallel Parallel configuration data bus serial Serial configuration data line (default) extclk Use external clock in master mode intclk Use internal clock in master mode fastclk Use fast internal clock slowclk Use slow internal clock -v Enable verbose output. -h Print a help text. ACTION SPECIFICATION One or more programming actions may be specified. Each action consists of a filename, optionally followed by attributes in the form <filename:ac- tion:offset:style:length>. filename The file to be written to the device, or the file in which to store data after reading from the device. On windows systems, a colon on po- sition 2 is considered as filename part and not as an action separator. action One letter indicating whether to write, read, or verify the device. If not specified, the default action is 'w'. w Erase, then write data from file to device and verify. W Write with auto-sector erase, then verify. v Verify device against file. r Read from device and write to file (no overwriting). R Read from device and write to file, overwriting existing files. offset The byte offset inside the device where programming/reading should start. Only supported for SPI, XCFnnS devices and XMEGA. style The format of the specified file. BIT Xilinx .BIT file format. Default for FPGA, XCF and SPI devices. BIN Raw binary file. BPI Raw binary file not bit reversed. MCS Xilinx .MCS file format. IHEX Intel HEX format. Also used by Xilinx PROMGEN when writing MCS files. Default for XMEGA devices. HEXRAW Raw sequence of hexadecimal digits. JEDEC Default for CPLD devices. length The number of bytes to program/read. Only supported for SPI, XCFnnS and XMEGA devices. DEVICE DATABASE The device database contains a list of supported JTAG devices. When xc3sprog starts, it scans the JTAG chain to discover all attached devices. A device database is used to map the 32-bit ID codes of the devices to de- scriptive names and get basic knowledge how to handle the part, at minimum how to skip it. A default device database is compiled into the xc3sprog executable. The database is tried to be loaded from a file at run time. If the environment variable $XCDB is defined, it specifies the name of the device database file, otherwise the file devlist.txt is read from the current directory. If a database file is not found at all, the internal compile-time database will be used. If a device is not yet know, the builtin list can be dumped, the informa- tion on the unknown part added and on the next run the new list will be read and used. CABLE DATABASE The cable database contains a list of supported JTAG cables. Each cable type is identified by a short label, such as pp, ftdijtag, or xpc. The database maps the label to parameters to be used to access the hardware of the cable. A default cable database is compiled into the xc3sprog executable. The database is tried to be loaded from a file at run time. If the environment variable $CABLEDB is defined, it specifies the name of the cable database file, otherwise the file cablelist.txt is read from the current directory. If a database file is not found at all, the internal compile-time database will be used. If a cable subtype (e.g. different VID/PID) is not yet know, the builtin list can be dumped, the information on the new cable added and on the next run the new list will be read and used. The database contains a line for each nown cable. The line consists of the alias for that cable to used with the -c option, the basic type of the ca- ble, the maximum allowed JTAG frequency of the cable and an optional option string. For FTDI devices the option string contains the USB vendor ID (VID), USB product ID (PID), the USB device description string, the FTDI channel of the JTAG interface and eventual commands for setting other pins beside the JTAG pins. e.g. to switch on some buffers. If the JTAG device uses a FTDI default VID/PID, the USB device description string is important to destin- guish your JTAG device from other eventual connected FTDI devices with the same VID/PID EXAMPLES xc3sprog -c pp -j Show a list of JTAG devices attached to the parallel port JTAG cable. xc3sprog -c ftdijtag -v -p 0 design.bit Program the specified bitfile into the first device (position 0) in the JTAG chain. Use an FTDI-based USB JTAG cable. Show detailed progress information. xc3sprog -c ftidjtag -T Test the integrity of the JTAG chain. xc3sprog -c xpc -p 1 dump.bit:r Read the contents from the JTAG device in position 1 in the chain, and write the data as a Xilinx .BIT file. Use a Xilinx USB programmer. xc3sprog -c cable -Ibscan_spi/xc3s50an.bit design.bit Load xc3s50an.bit into the FPGA in position 0 in the JTAG chain. Then, program design.bit into the ISF memory in the FPGA. xc3sprog -c cable -I image.bit:w:0x10000 Program the image file into the SPI memory attached to the FPGA, start- ing at byte offset 0x10000. An appropriate bscan_spi file must already be loaded in the FPGA, so that it will act as a bridge between the JTAG cable and SPI bus. ENVIRONMENT XCDB Name of the file to use as device database. The default is de- vlist.txt in the current directory. CABLEDB Name of the file to use as cable database. The default is ca- blelist.txt in the current directory. XCPORT Parallel port device to be used for JTAG cable type pp. The default is /dev/parport0. This setting may be overridden by command-line option -d. XC_MAPDIR Default directory to search for XC2C map files. This setting may be overridden by command-line option -m. JTAG_DEBUG If specified, a log of JTAG operations is written to a file with this name. FTDI_DEBUG If specified, a log of interactions with the FTDI device is written to a file with this name. Only used for FTDI-based cable types. XPC_DEBUG If specified, a log of interactions with the XPC programmer is writ- ten to a file with this name. Only used for XPC-based cable types. SPI_DEBUG If specified, a log of SPI operations is written to a file with this name. Only used in ISF mode. PDI_DEBUG If specified, a log of PDI operations is written to a file with this name. Only used when programming an Atmel XMega device. FILES devlist.txt The device database, containing a list of known JTAG target devices. This file is read from the current directory by default, or from the location indicated by the XCDB environment variable. If not found, an internal compile-time version of the device database is used. cablelist.txt The cable database, containing a list of known JTAG cable types. This file is read from the current directory by default, or from the location indicated by the CABLEDB environment variable. If not found, an internal compile-time version of the cable database is used.
