Hi everyone, MiSoC (http://m-labs.hk/gateware.html) now supports the mor1kx CPU in addition to the original LM32. You can choose mor1kx at compile time by adding "-Ot cpu_type or1k" on the make.py command line, e.g. ./make.py -Ot cpu_type or1k all ./make.py -Ot cpu_type or1k -p m1 -s FramebufferSoC all
...and that's all, make.py also configures the software build environment to use the selected CPU. For a demonstration of the functionalities of MiSoC on a simple design, have a look at this example: https://github.com/m-labs/blinkie (You can use mor1kx with blinkie, just as well as LM32, by using the same command-line option) All that SoC targets which support or1k need to do is pass the cpu_type argument to the GenSoC constructor. The recommended way to do it is to pass any supplementary keyword arguments to the parent SoC classes using **kwargs. NB: BIOS execute-in-place from the flash on the Papilio Pro does not work with or1k for some reason - I suspect it is reset timing related, as it also breaks on LM32 when loading the bitstream to SRAM via xc3sprog. It works fine on Mixxeo, or when using IntegratedBIOS. Sébastien _______________________________________________ OpenRISC mailing list [email protected] http://lists.openrisc.net/listinfo/openrisc
