Hello,
'am not sure where to post this.
I've been searching for a good while now,
but can't seem to get a hit, or most likely I'm
not using the right keyword.
I'm attempting to port this github.com/Wireb/PICnc-5axis
to an stm32f4 (micro). I think I got the handle on the micro side,
I'm testing it with a tinkerboard-s (got it a year ago but drivers wasn't good back then).
I've tested spi communication with my tinkerboard and the micro and
it seems to be working as expected.
So I got LinuxCNC (lcnc) pre2.9 uspace running on my board
with Slackwarearm on it with minimal Xfce 5.4.54 kernel PREEMPT_RT
The sim works fine so I'm off to the next stage.
I'm not exactly sure how to build the module.
How does one compile a module?
My limited search hit lead me to halcompile.
I tried:and after correcting mistakes I managed to get
the_module.so and copied it to rtlib directory.
Now trying to run lcnc with example ini and hal
modified to fit the_module name in the C codes.
I get:and not really much information in the logfile.
I thought maybe I should be compiling withnow I get these:highlighting the string constant "GPL",
same goes to the rest of code with MODULE_ in it.
So how to properly write/compile a module?
Any pointers, docs to read, encouragedment/discouragement
is welcome.
tinkering...
Edit:
...wrote too soon, back to square one.
Edit last:
Darn I'm so dumb (probably too harsh, maybe blind), there's a whole section above that has everything HAL on it

It turns out its a spi device permission problem.
It's not easy doing everything from scratch.
I'm proud to say that my halcmd test is communicating
with the stm32f4 board...unfortunately that's all there is to it for now.
