Welcome to or1k-tcltools ! ========================== 1) Introduction --------------- or1k-tcltools provides a series of Tcl scripts working together with the OpenRISC processor used on Altera platforms using the Virtual JTAP TAP and the Advanced Debug Interface. The Quartus II graphical user interface provides the Tcl Console, which allows you to control the Quartus II software with Tcl commands and scripts. Each of the Quartus II executables— quartus_sh, quartus_map, quartus_fit, quartus_sta, and others— also functions as a Tcl interpreter. Depending on wich executable is used, different packages are loaded into memory. The JTAG package is only available with quartus_stp. The JTAG package provides a set of Tcl functions for controlling the JTAG chain using Altera programming hardware: close_device device_dr_shift device_ir_shift device_lock device_run_test_idle device_unlock device_virtual_dr_shift device_virtual_ir_shift get_device_names get_hardware_names open_device Thus, the Virutal JTAG instance controlling our Advanced Debug Interface can be controled from the Tcl script. 2) Provided files ----------------- defines.tcl --> Defines for debug interface controled functions.tcl --> Helper functions loader.tcl --> Low level control of the JTAG / debug interfaces download.tcl --> Download and run ELF executables (or1krun function) or1k-download.bat --> Start or1krun from a Windows command line run.tcl --> Startup script used by the or1k-download.bat file 3) Usage -------- * From a Windows/Linux command shell: or1k-download "yourfile.elf" * From a Tcl console: source download.tcl or1krun "yourfile.elf" Using the Tcl console you also have access to the "registers" command. This command shows you the registers values.
