hi,

I am using the DM355 EVM ,DVSDK1.30.

1. There is a EEPROM on SPI0, what does it used for?

2. EEPROM connectted with DM900, what does it used for?

thank you!

See page 21 of :

Is it possible if I  remove these EEPROMs on my own PCB?

Is it easy to modify the softwares?

thank you!

I think this would depend on your design and the ethernet controller you choose.  my understanding is that some ethernet controllers have built-in memory where to store the EMAC address, others rely on external devices such as EEPROM on our EVM.  Therefore, depending on which ethernet controller you use, you will need to design your board accordingly.

thank  you!
