v1.1

Behind-the-scenes work: clean-up of symbol and footprint libraries. Remove external library dependencies

Many small design improvements, tracked as closed issues:

• Annoying MMC reset behavior #60
• Fan connectors not functioning #59
• Missing I2C pull-up resistors on I2C PM bus #57
• Keep some I2C busses running with only +3V3P #56
• mini j-link segger connector #54
• Add mounting holes #49
• Updates targeting next fab run #48
• Unclear which capacitors are populated on MGT_CLK_*_P/N lines #47

marble-mini-5f98e670-fab.zip contains the fabrication files for the standalone build variant of the board (not meant to be used in an AMC chassis).

Errata:

• U6 supplies are incorrect, preventing MDIO access to Eth PHY (without rework)
• 88E1512 CONFIG pin strapping incorrect: currently set for VDDO_LEVEL = 3.3V and non-standard phyad=0
• D6 and D7 need to be rotated 180 degrees to allow PoE operation

v1.0rc3

Released after the first prototype boards have been received and tested.

tested ok

• power supply
