Eeprom programming working and failing on different computers

[arbite]

I have moved from an old reliable Optiplex 745 desktop to a new Topcon small computer and have an application running well on both computers using SOEM. I do have to run a script on the Topcon router that sets NIC rx-usecs etc to get the application to run reliably.

I went to program the eeprom for some new slave hardware on the new Topcon computer. eepromtool reported that it programmed successfully. However the slave will not work with my application and slaveinfo fails and shows a seemingly corrupted eeprom.

I thought my new hardware was bork. In a fit of desperation I fired up the old computer and programmed the eeprom. It works fine! I was able to program all my boards.

I wondered if the new computer had a bad install of SOEM or something. I copied the eepromtool binary from the old working computer to the new computer. It will not program the eeprom! This is very strange.

Can anyone offer any advice? I really want to retire this old computer....

Here is some output from eepromtool and slaveinfo:

Not working: Here is programming the slave using the new computer. Note the total EEPROM write time.

newcomputer:~/SOEM/install/bin$ sudo ./eepromtool enp3s0 1 -w eeprom_file.bin SOEM (Simple Open EtherCAT Master) EEPROM tool ec_init on enp3s0 succeeded. 1 slaves found.

Here is slave info on the new computer after programming with the new computer. It fails. At first glance it looks ok, but the output size is incorrect along with some of the other data. On previous attempts the Name entry was garbled, with only some parts of the text "arbite_device" showing correctly.

A wireshark capture of the new computer doing an eeprom programming would help.

Hi Arthur, Apologies for the delay. I've attached a capture of the new computer attempting to program a new board. The program attempt looks correct, but when I do a slaveinfo the eeprom image is incorrect. Thanks again
