According to Microchip document AN1290 "Microchip LAN9252 EEPROM Configuration 
and Programming" It seems Slave Stack Code Tool is needed but this is only 
available for members. I asked for membership but they required a company 
website to get membership and I could fix this but it takes time.

If I know the protocol for programming EEPROM via Ethernet maybe I could do it 
myself. Other option is to program EEPROM from micro controller via I2C or 
simply configure micro controller as a slave so LAN9252 could read 
configuration from micro controller.

Yes I have no idea either what scan do or what it is supposed to do. Zero 
information is printed so it is impossible to do anything more than pressing 
the stupid button, neither is possible to write something manually.

I used Twincat3 but have no idea what it does to scan the network and then 
connected to switch Wireshark do no spot any Ethercat packets.


That is really odd.  It seems to me that it would be really helpful to 
be able to see TwinCat initialize the secondary via Ethernet if you can 
grab the packets via Wireshark.

Yes I tried both ports and soldered the EEPROM. Software in micro controller is 
not an issue because SPI port is not turned on until configured by the EEPROM. 
I will give up Twincat since I should not use it and continue with Ethercat 
master for linuxcnc which I should use.

It feels a little bit odd LAN9252 need to be configured via network before it 
could communicate with micro controller via SPI.



Did you install TwinCat 2 or TwinCat 3.   I have TwinCat 3 loaded on a
laptop here.

I used Twincat3 but have no idea what it does to scan the network and then 
connected to switch Wireshark do no spot any Ethercat packets.

Tried it and nothing happened.

I will try to connect micro controller to EEPROM socket, it could be done in 
parallel so I could use micro controller to program EEPROM.

I use twincat 3 but there are two switches in between on the local network. I 
can't see any Ethercat frames on the local network then running scan. Maybe I 
should connect Ethercat card directly to computer.

I tried but it did not find any devices, link LED is turned on, it might be 
because device is not yet configured but this is supposed to be done in Twincat.

With cable connected to SPI port at correct edge and direction connection LED 
is turned on both switch and LAN9252 Ethercat board. Just have to figure out 
howto scan the Ethernet network and buy a EEPROM.

Basic problem is I do not know how to get LAN9252 started. Crystal is up and 
running but nothing happens then I insert a Ethernet cable. SPI is not running 
since it read configuration from EEPROM but how do I program configuration? 
Maybe I should program EEPROM before soldering it to board?

On page 24 in the datasheet for LAN9252 are the SPI pins. Data is sent out but 
I get no answer on MISO pin. On page 296 is the PDI control register at adress 
0x0140 and this is read from EEPROM. It make me a little bit confused because 
how do I program value then SPI is not enabled and EEPROM is connected to 
LAN9252 circuit?

[Roland Jollivet]

looks like it according to page 24

These pins are the Distributed Clock Sync (OUT) or
Latch (IN) signals. The direction is bitwise configurable.
Note: These signals are not driven (high impedance) until the EEPROM is
loaded.

Software is loaded into to chip and try to communicate via SPI but get no 
answer. I try to run without EEPROM so it might be I have to add this to get 
correct configuration, datasheet for LAN9252 make me a little bit confused 
about if EEPROM is needed.
