[Puzzl88]

How do enable 1-wire on the BTT-Pi, specifcally for the DS18B20 sensor?

Hmm, maybe I forgot a package, I'll take a look, thanks

I understood what's the problem. After LN -s/Lib/Modules/Uname -r/Build/Include/Linux W1, you need to execute a command make.

Thanks for the help!

ah, great, I'll update the guide, thanks!

sorry, i'm a unix newbe - i get the following error:

biqu@voron:~/w1-gpio-cl$ sudo make NOTE: ./w1 symlink is already set and will not be updated. Remove it and restart the compilation process in case you want to re-run the kernel sources examination. NOTE: gen-mast.h was generated make -C /lib/modules/5.16.17-sun50iw9/build M= modules make[1]: Entering directory '/usr/src/linux-headers-5.16.17-sun50iw9' make[2]: *** No rule to make target 'arch/arm64/tools/gen-cpucaps.awk', needed by 'arch/arm64/include/generated/asm/cpucaps.h'.

[mdvorak]

Hmm, that is wierd error :-)

[mdvorak]

I've managed to reproduce it with latest packages, maybe it was caused by some recent system update, I'll investigate it.

@wmetnitz Found it. make needs to be run without sudo, for some reason, it messes up env vars and compilation fails to find some files. Also for the compilation itself, sudo should not be really needed. I was originally running it all directly as a root, so I did not encounter this problem.

Guide updated.

note: sudo -E make seems to work fine too.

Hi, i don’t know, what goes wrong ☹

The installation seams ok, but:

==> sudo echo 'options w1-gpio-cl m1="gdt:71"' > /etc/modprobe.d/w1-gpio-cl.conf

got permisssion denied.

Now i created this file manually.

==> sudo modprobe w1-gpio-cl

-rw-r--r-- 1 root root 31 Oct 4 17:47 w1-gpio-cl.conf

@.***:/etc/modprobe.d$ sudo modprobe w1-gpio-cl

modprobe: ERROR: could not insert 'w1_gpio_cl': Exec format error

• sudo modprobe 21-gpio-cl m1="gdt:71"

@.***:/etc/modprobe.d$ sudo modprobe w1-gpio-cl m1="gdt:71"

modprobe: ERROR: could not insert 'w1_gpio_cl': Exec format error

What goes wrong?

Many thanks,

Werner

That was entirely mistake on my side, sorry!

echo 'options w1-gpio-cl m1="gdt:71"' | sudo tee /etc/modprobe.d/w1-gpio-cl.conf
echo 'w1-gpio-cl' | sudo tee /etc/modules-load.d/w1-gpio-cl.conf

I needed a tester, thanks
