Hello i have two questions. 1.) I intend to use i2c eeprom as configuration device. This is standard mic rochip device. However i want to use 1024Kb (24AA1026-I/SN) which has only to pins to configure the address. Will fx3 still be able to recognize this device? 2.) Since i will use only i2c for configuration, what should i do with pins for uart, i2s, spi, jtag ... should i connect them to ground or leave floating? thank you

Hi,
Please look at this
The I2S, UART etc are not configured so by default. If you're not using them you'll be configuring them as GPIOs so it depends on how you configure them in your firmware

Yes, All unused pins can be left unconnected/floating (including JTAG pins).
