Many new programmable devices contain a JTAG interface that is standardized. You can use it for programming any JTAG devices even when they are not listed in the device list. The data to program must be available in SVF (Serial Vector Format), XSVF, or JAM format. Data in other formats can be programmed using the OpenOCD software.
Programming with XSVF and JAM files works the same way as for SVF-files; XSVF– Xilinx binary format of SVF, JAM - SVF-like script files with more complex content.
Select Device/SPECIAL/JTAG/SVF_PLAY for running SVF-files through JTAG. A SVF interpreter generates the JTAG control signals on Galep4 or Galep5 pins. The SVF-file (*.svf) has to be generated by the user. It contains the required actions such as erasing, programming, verifying or testing the device.
The JTAG target has to be connected as described below.
Load SVF file to buffer. ( selected data type is *.*, with load as „svf“ in file type selection).
Select the target digital logic level in JTAG-Options menu.
Execute the SVF file with PROGRAM F3 action. Other actions will not work.
Only one JTAG device connection is supported. Device chains with additional header and trailing JTAG-devices are not supported. The SVF commands HIR ,HDR, TIR and TDR are ignored (bit number is set to 0 preliminary).
The SVF-commands „PIOMAP“ and „PIO“ are not implemented and will be ignored.
Set FREQUENCY to 500000 for SVF compiler. GALEP provides a maximal TCK frequency of 500KHz.
It is not possible to read back any device contents.
You do not necessarily need to use the ISP adapter. Connect only the related Galep4- or Galep5 Pins and GND to your target JTAG port:

Galep5 Pin No. |

Some programming interfaces require a power supply by the target. This pin is not connected to Galep power supply and not supported by Galep. |
