10.10 FRAM

The unit supports an optional non-volatile Ferroelectric RAM (FRAM) device. The Fujitsu MB85RS16N is a
2kbyte device, in a configuration not unlike an SPI EEPROM. However, the nature of FRAM means it is non-
volatile, incredibly fast to write, and is specified with 1 trillion read/write cycles per each byte and a 200 year data
retention. The device is connected to Linux and presents itself as a flat file that can be read and written like any
standard Linux file.
The EEPROM file can be found at /sys/bus/spi/devices/spi32766.0/eeprom

10.11 I2C

The i.MX6UL supports standard I2C at 100 kHz, or using fast mode for 400 kHz operation.
The kernel makes the I2C available at /dev/i2c-# as noted above. Linux i2c-tools (i2cdetect, i2cget, i2cset) can be
used to interface with devices, or custom clients can be written (https://github.com/embeddedarm/linux-
4.9.y/blob/master/Documentation/i2c/dev-interface) .
