Can you share how to create the eeprom content from an XML file?

Ok, I have seen those.
When you write an eeprom this way and then list the pdos with "ethercat pdos", do you see the ones you expect to see?

accidentally flashed my ethercat servo with something wrong, and restored everything with this tool and the original esi xml

so yes, it really works

I use it to configure my LAN9252 board

EDIT:
uhhh, found this site: markosankovic.github.io/2016/06/28/esi-to-sii-binary.html
i think i need to test this '

Code:

ethercat sii_write ...

'
I must have overlooked it somehow
