"gaps" with 0x000 x00 was created by ftree

Hi!

Can you help me solve this error? The etherlab driver does not like PDO gaps with x0000 x00 ? What are my options?

I tried searching for a simialr problem on here in vein. I hope that a new thread with the exact problem would be better than than conversation buried deep in another thread.

I see "gap" 0x0000 x00 in several of the other "linuxcnc-ethercat" drivers so it does not appear to be a problem....

Maybe it is the version of "etherlab" i am using that is more strict.

how did you install the etherlabmaster? Are Sittners patches and the Gavin Lambert patchset applied?

I'm using this linuxcnc master
github.com/sittner/linuxcnc-ethercat

and this Debian_11 repo
download.opensuse.org/repositories/home:.../EtherLab/Debian_11/

*** Sittners patches and the Gavin Lambert patchset - ???

if you install etherlab with ec-debianize, there will be applied some patches from sittner and an bigger patchset from gavin lambert.

But ec-debianize is a bit outdated. I have not installed debian 11 yet, so i did not need to create an ethercat deb11 way for me yet.....

I have to check if one of the patches includes something that is related to pdo configuration, but i am on tour at the moment. Time is critical....

As for Saschas and my lcec drivers/components gaps have ever worked.

I think the build process for etherlabmaster is obsolete and needs to be ignored. It certainly does not work with Debian 11 and on. It follows the old etherlabmaster repository before they transitioned from mercurial to gitlab. How can it be safe to use?

It is no longer necessary to do the etherlabmaster build process if you use the repository for etherlabmaster and install as I described here:
forum.linuxcnc.org/ethercat/45336-etherc...-how-to-step-by-step

I thought I read somewhere that the patches are no longer necessary as they have been rolled up into linuxcnc master branch or into etherlabmaster itself.

I have certainly not found it necessary to install the patches with the method in the sticky I linked to here.
