Description of Change
- enhancement: JTAG only boot mode is now supported.
- enhancement: Winbond W25Q256FV SPI Flash memory replaced with Spansion S25FL256.
- replacement: Texas Instruments TPS51200 Sink/Source DDR Termination Regulator replaced with TPS51206.
change: changed MDIO pullup from 10k to 4k7.
- change: changed eMMC core supply from switched 3V to 3.3Vin no .
- change: MAC EEPROM power changed from 3.3V to 1.8V, no impact on user design.
- I2C Multiplexing no longer needed (to select between RTC and MEMS), all I2C devices are on same bus.
- removal: ST LSM303DLM (e-compass: 3D accelerometer and 3D magnetometer) MEMS is no longer assembled (footprint only).
- removal: removed test pads on top layer.
- enhancement: increased component clearance from mounting holes on bottom layer.
Reason for Change
- Spansion S25FL256 is supported by current Xilinx design tools (ISE14.7, Vivado) W25Q256 is only supported by u-boot, linux and Vivado SDK Programmer.
- TPS51206 was changed due to BOM optimization.
- ST LSM303DLM MEMS has been discontinued.
Application Impact
