I think the chance is more than 50% that it works. I have an "unsupported" builtin network interface and the GENERIC driver works just fine.

I looked at the gitlab code and maybe it is better to be at the source of everything. But I couldn't find anything that fixes your problem.

I looked around in the code. This is what it looks like when the problem occurs.
#ifdef EC_DEBUG_RING
#define EC_DEBUG_RING_SIZE 10

typedef enum {
TX, RX
} ec_debug_frame_dir_t;

typedef struct {
ec_debug_frame_dir_t dir;
struct timeval t;
uint8_t data[EC_MAX_DATA_SIZE];
unsigned int data_size;
} ec_debug_frame_t;

#endif

So the code is surrounded by the #ifdef EC_DEBUG_RING so I think this code is active only when debugging is switched one. If you could switch off the debug and undefine the EC_DEBUG_RING, then this piece of code will not be active and it should be smooth sailing to build the kernel modules.

I can't help, I don't have a 5.10 system. And to find how to do this using ec-debianize well that is why I went away from it in the first place.

Thanks, I had another go today using the igh git and then your git on a pi.
Both failed at exactly the same place. Looking for a network driver for the 5.10 kernel in the ethercat source.
I think I'm between a rock and a hard place. It won't install on bullseye and I can't use Buster because I need the NIC driver that is included in Bullseye. Its an extentsion to the RT8169 driver which is supported by ethercat. Last time I tried the LCNC 2.8 .ISO on this PC, it would not install without a network connection so I could not get far enough to install the network driver.

2.8 would be ok for this machine. I might look at Linux Mint again with 2.8. I'm that used to working with master branch for plasma...

Silly part is I have an older pc running Debian 11 and ethercat.... It coming to work with me tomorrow :)

Hi Rod,

Problably this will work:

dpkg -i ethercat-master.deb
/opt/ethercat/script/init.d/ethercat restart

Grotius, thanks, I will give it a go I think.
Hopefully, I should be able to install my NIC driver after it is installed

I was wrong here. Its running debian 10 by the look of the kernel version...

Hi Rod,

Problably this will work:
wget github.com/grotius-cnc/Linux-Pro/release.../ethercat-master.deb
dpkg -i ethercat-master.deb
/opt/ethercat/script/init.d/ethercat restart
 

A couple of errors. my network NIC is  enp3s0

I tested to build from the source I use on Raspbian and there were two compilation errors when building the modules. It uses 5.10.something.
I had to change to "static unsigned int" on line 91 and 259 (I think) in cdev.c and then it compiles. Never tried it but that change is so minor that I think it will work.

Hi Rod,

I made a custom .deb package for you where the network nic is set to : enp3s0
To overcome the permission denied error, first perform these 3 terminal things :
# 1.Set user permissions /opt dir.
sudo chmod -R -f 777 /opt

# 2.Change owner /opt dir
sudo chown -R $USER /opt

# 3.Change group /opt dir
sudo chown -R $USER:$USER /opt

# 4.Install Rod's custom deb package
wget https://github.com/grotius-cnc/dump/releases/download/1.0/ethercat_rod.deb
sudo dpkg -i ethercat_rod.deb

Grotius, you are indeed a magician, I can now list the slaves!
Thank you very much.

But I am having trouble opening my config. I suspect files may not be in the right spot yet because of the shortcuts we took.
I had to manually copy some files to the /lib/linuxcnc/modules folder but still they do not open. Any ideas here?

I suspect I need to install the linuxcnc-dev deb. Will regroup tomorrow.

Well, I made some progress following advice on this forum.
At least the xml is opened and parsed but
Now I get:
lcec: dlopen: libethercat.so.1: cannot open shared object file: No such file or directory

I am hoping this is just a path issue. Help would be appreciated
