## EEPROM
You need to fill the EEPROM with valid contents before putting it on the pcb. It is actually a must, the EtherCAT IC will not start with an empty EEPROM, or with a non-valid content. It doesn't have to be for a real EtherCAT slave, because the first thing you will do when the card works is to upload the correct contents using TwinCAT. Any valid EEPROM content.

There is a small Arduino program [Link here](Utils/EEPROM_store_valid/) that helps to fill the empty EEPROM. Follow the link.

## Soldering
I have put the pcb in the soldering oven. Hand soldering should work, although the pin spacing is only 0.4 m on the Ax58100 IC and can be a challenge.
I have put the pcb in the soldering oven. Hand soldering should work, although the pin spacing is only 0.4 m on the Ax58100 IC and can be a challenge. I usually get some solder bridges on the EtherCAT IC or the STM32 chip. A magnifyng device definitely helps.
