mir toolset not working

[petex]

hello,
did a bog standard install of toolset from fcupdeluxe. Get error compiling project1.

Just for me to understand:

You tried to compile the empty default project that opens up when you have built & installed a fresh copy of fpcupdeluxe?

Or did you open one of your projects and that one failed?

please provide a copy of the lpi file you used...

[petex]

i installed a fresh instance of lazarus,fpc and embedded compiler. I then tried to build a working project using the existing compiler i have been using for embedded and I got the error.
I then created a new project, changed the target to embedded with no compiler switches and i got the same error.

Am i using the correct combination in fcup ? I am using the toolset to build STM32 projects and I thought I would keep up with latest changes, especially with the pico.

[MiR]

only setting embedded is not enough you have to tell the system to use arm, subarch and put in a correct -Wp.

Please clone the pico repository and open an lpi provided there and try compile.

Sharing your lpi will make helping you a lot easier, my magic glass spere is a litty cloudy atm, I cannot see what you actually tried to do...

Also it is important to have the correct subarch compiler, please check the doku on the wiki....

What folders did you install the new and old instances into?

You will need to provide more info to get good troubleshooting assistance...

Toolset was installed to "C:\fpcupdeluxe-mir"

[MiR]

The relevant entries are in, did you compile a cross compiler for armv7m?
If that is the case then try a full clean before build.

Minor thing:

-dbluepill is not needed anymore unless you need it for yourself.

I just now realized this entry:

Verbose: PPU Loading C:\fpcupdeluxe-mir\fpc\units\arm-embedded\system.ppu

and that is likely the cause of the issues.

This directory should be C:\fpcupdeluxe-mir\fpc\units\arm-embedded\armv7m/eabi/rtl/system.ppu

Not sure how this happened, can you please put your fpcupdeluxe binary in an empty directory, then delete fpcupdeluxe-mir and start fpcupdeluxe from the empty directory?

Then select sgain the  C:\fpcupdeluxe-mir directory and build fpc+lazarus and then build the compiler for arm-embedded armv7m.

Do not modify the settings in the subarch dialog, only select the subarch you would like to use and close the dialog

OK, have re-installed as directed.
Now get "Fatal: Can't find unit lnfodwrf used by project1" - had this before, can't remember how it was corrected though.

Sorry, no idea, I think I had this once when I compiled code with -dDEBUG but I may be totally wrong here.

Can you please clone pico code (and install armv6m crosscompiler) or compile some mbf projects to find out if it is your project or a general problem?

[DonAlfredo]

Disable line-info in debug options or disable debug as a whole.

[petex]

ok, all is well, can compile my existing projects and the pico blinky project. The pico bootloader runs the blinky.uf2 file ok.

I have been using a Raspberry PI to run the openocd remote gdb debugger with the STM32. I now want to use the same configuration with the pico. (I do not have a second pico which looks like the easy option) I cannot find the 2040 configuration for it. Any ideas on how to get this working. (I am upgrading openocd on the PI at the moment-but it takes a long time)

[MiR]

https://datasheets.raspberrypi.org/pico/getting-started-with-pico.pdf

has you covered. Google would also been able to tell you so.

[petex]

Well, i looked at the docu and re-installed openocd using the recommended script.
Got the debugger working with the pico blinky build with a gdb server on the rpi. Great!!

My original STM32 setup however has been prevented from working. It initially complained about the target speed not set, so i added "adapter speed 1000" to prevent that error but the GDB server doesn't start..... There's also confusion about whether it should be "adapter_khz 1000"

Seems that openocd has been changed and is not backwards compatible. At least i won't need a haircut.

You could try to recompile your old version again and install it in another directory (or use it from the directory where you compiled it)

[petex]

luckily i have put the source and compilations in two separate folders.(these took a very long time to do) So at the moment i can re-install the required version with

sudo make install

That doesn't take long. I am not enough of a unix wizard to simplify the job.
