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.

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