What sw tools do i need for a bare-metal design?

As the title says.

For compiling i may want to use the "arm-none-eabi" cross toolchain with newlib.

Could i do some useful debugging with openocd&gcc via the byteblaster?

Is there a example startup.S or can i adapt parts of the preloader sources?

    In SoC EDS is present many examples of startup.S (c:/altera/14.0/embedded/ds-5/examples) for many boards.

    Also in this last version baremetal compiler utilites is renamed to arm-altera-eabi-*.

    If you will find free good soft for developing non-Linux apps on Altera boards, please describe here in detail with direct links !

    Recommended DS-5 Altera Edition is very crude and not free.

    I think that ByteBlaster may be used with appropriate connector to JTAGs, only will be slow speed.

    I just installed Q14 Web and don't have the "embedded" folder.

    Is this from ARM-DS or the subscription edition?

    Seems one has to spend quite some money to be able to do a simple bare metal C-V SoC design and also will not be able to use his "good old" known arm-gnu toolchain with openocd.

    I think about using separate devices mcu + fpga for flexibility and cost again, because i think the FPGA companies still need some time to get "SoC" easy and low cost to work with.

    Dowload and read ug_soc_eds.pdf from Altera site all from top to bottom !

    DS-5-AE from SoC EDS may be used free for onboard Linux developing, and 30-days license for B-M may be free.

    All files in folders may be readed absolutely free after install... :)
