Semihosting STM32F407 under Win8, gnu...

[mik00]

Have YOU made semihosting work on the STM32F407?
Please send me a: "Yes!", or a "No, I failed too"

I'm using a [b]PC (Win8) and the gnu toolchain[/b], [b]cross tools[/b], and the [b]STMF4xx example program[/b] that blinks an LED. I'm not sure I have everything set up correctly, but I can't find a definitive document describing the current configuration process.

I can compile, and even debug the semihosted example program, but it simply halts at the first trace statement. Other people have given up, so I don't want to dig into this unless there is evidence that it works.

[list][]Can you point me at the definitive configuration document?
[]What are the correct configuration settings?
[*]What is the right ST-LINK firmware? I upgraded to V2.J19.S0 and it chokes somewhere during the flashing process. Downgrading to V2.[b]J15[/b].S0 worked OK. Any confirms on that? Has the protocol changed in J19?[/list]

If it can be made to work I'll write a guide document.

Semihosting is not supported by stlink project tools (currently). You have to use OpenOCD for this.

Support for ARM semihosting was added to st-util in Release v1.3.0.
