Slaves do not reach safe operational state LAN925

[bremenpl]

Hello there, I have managed to make the library work properly under windows after a while. For my project I have build mysalfe 2 boards based on LAN9252 chips. I am not an expert in etherCat, as I just started using it. When I run slaveinfo.exe with the devices I see (while debugging) that they are still in state EC_STATE_INIT not in EC_STATE_SAFE_OP (but that it also known from the console output). But then again it says "No error".

I was wondering what has to be done to enable the slaves to go into operational state? I havent configured them with software yet at any point, they are set to defaults. Are there any additional steps I should take? I would appreciate all help!

It looks like the slaves does not have a proper EEPROM.

[bremenpl]

But do you mean that the contents of the EEPROM is wrong or is the EEPROM chip invalid?

[mheden]

It looks like the EEPROM is empty, i.e. the content is wrong.

[bremenpl]

I see. It indeed is empty as I dont know how to program it yet. Do you know maybe either this eeprom chip should be programmed first before soldered to the board with LAN9252 or can I do it via etherCAT using the LAN9252 chip? Do you have maybe any experience with this chip?

[mheden]

You can use the eepromtool available as a test application in SOEM. This writes the EEPROM via EtherCAT.

@bremenpl , I began to design an ethercat slave board with this chip using the SPI interface. My board schematics will be opensourced , do you provide your schematics or is it private ?

[bremenpl]

I believe certain parts of the schematic, that concern this functionality can be shared :)

[mheden]

Did you manage to write the EEPROM?

[bremenpl]

Not yet :(, the project got put back for a while.

[mheden]

Any news regarding this issue?

No response - close.
