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
