Hi Oguz, It’s not looking likely to be an SII problem then.
From the log it looks like you’re using a single Read/Write domain. I don’t recall if you mentioned, have tried putting it in separate read and write domains? If you try this, also ensure that there are at least two other separate read and write domain slaves also configured in your system. I’ve had a few slaves in the past (generally with Texas Instruments ESC’s) that work well with overlapped PDO’s in a single Read/Write domain (TwinCat’s default method), but fail when the PDO’s are not overlapped (EtherLab’s default). If this is the case you can put them in separate read and write domains to separate them within the EtherCat frame. But, you need to ensure there’s a couple of other read and write domain devices also configured to ensure there’s enough separation in the frame. Graeme.

Hi, I noticed, the correct path with option is: "--enable-sii-override=/lib/firmware" This way, the master can find my ec_xxx.bin file. But still at the end, slave doesn't respond to go INIT command. Here is the dmesg output: https://we.tl/t-BGDmNzZv2b Best regards, Oguz.
