Raspberry Pi 4

I tried again to build linuxcnc-uspace on my rockpro64 but I am getting some errors on
"sudo dpkg -i linuxcnc-uspace_2.8.0~pre1_arm64.deb"

(Reading database ... 185225 files and directories currently installed.)
Preparing to unpack linuxcnc-uspace_2.8.0~pre1_arm64.deb ...

dpkg: dependency problems prevent configuration of linuxcnc-uspace:
linuxcnc-uspace depends on python-gtksourceview2; however:
Package python-gtksourceview2 is not installed.
linuxcnc-uspace depends on python-vte; however:

linuxcnc-uspace depends on gstreamer1.0-plugins-base; however:

linuxcnc-uspace depends on python-xlib; however:

The instructions say:

Now edit debian/control.bottom.in and remove the following lines
python-gtksourceview2
python-vte,,

but the lines are not in debian/configure so I can't delete them.

So does anybody have any suggestions??? They are obviously being referenced from somewhere.

What does that mean?

It sounds like the 7C80 uses a Hostmot2 module that is not currently supported by the LinuxCNC driver.
Hostmot2 defines a number of modules, with an identifying code:
github.com/LinuxCNC/linuxcnc/blob/master...tmot2/hostmot2.h#L92
(I suspect that some marked as "not supported" are actually now supported. But "inmux" is not even listed.)

Each GTAG type has its own driver file, for example GTAG 128, led, is handled by led.c
github.com/LinuxCNC/linuxcnc/blob/master.../mesa-hostmot2/led.c
(I chose that one as it is the simplest of them, but all the driver files follow the same structure)

The very first thing I did with LinuxCNC coding was write the tp_pwmgen driver to enable use of the 7i49 card. If you fancy a project....

Thanks for the information Andy. If I only had time for all the projects I have active now:(

I have finished the inmux module driver but its not merged into LinuxCNC yet

I have a bunch of new modules, and some additions that are not merged yet

7C80/7C81 Berthos RPI4 fixes+ my 7C80/7C81 support

Offset PWM mode added to PWM module

Inmux module support (7C80, 7I95, 7I97)
(inmux is input multiplexer for Input expansion, adds digital filter on inputs and 4 MPG counters with 1x/4x modes)

7I94, 7I95, 7I97 Ethernet board support

If I am interpreting that correctly, that sounds like fantastic news for everyone that wants to use the RPI4 with the 7C80 board. THANK YOU VERY MUCH!

Well if I could just read. I missed the "edit debian/control.bottom.in". Running the process now.

Humm, the last time I did that, for a 7i90HD mesa card, I didn't have a debian/control.bottom.in file? What else did I miss?

I am slowly taking 1.6mm off the heat sinks legs because the heat conductive padding I got from Startech is about that much thinner than what came with that covers the whole top of the rpi4 heat sink. There legs are so fragile, I'm going .1mm at a time, sweeping y, then dropping z. At the feeds, almost 4 hours a leg, I could speed it up with a bigger stepover and a deeper cut, but those legs next to the gpio pins are nearly as fragile as a soap bubble. When I remount for the front legs, which are much stouter, I'll double both cuts.

Thank you.
