Changes

#1 Changed DCDC EN5311QI (U11) to MPM3834C (U5) and adapted power circuit.

Type: Schematic Change

Reason: EOL of Component.

Impact:

...

None. Increased current output capability. Minor changes in electrical characteristics.

#2 Changed DCDC EN6347QI (U10) to MPM3860GQW-Z and adapted power circuit.

Type: Schematic Change

Reason: EOL of Component.

Impact: None. Increased current output capability. Minor changes in electrical characteristics.

#1 Changed HyperRAM (U4) from S27KS0641DPBHI000 to ???.

Type: BOM change

Reason: HyperRAM improvement.

Impact: None. ???

#7 Added jumper (J3) option (default: not fitted) and resistor (R36) to enable JTAG only boot mode.

Type: Schematic Change

Reason: QSPI programming problems with newer Vivado versions.

Impact: None. JTAG boot mode directly accessible. Fix QSPI programming problems with newer Vivado versions according to AR#00002 - QSPI Programming issues.

#6 Added diode (D1) between signals "INIT" and "PROG_B".

Type: Schematic Change

Reason: Keep FPGA in reset while signal "PROG_B" is low during initial power-up.

Impact: None.

#5 Added diode (D4) between voltage monitor (U9) pin 3 net "nRST" and voltage rail 3.3V.

Type: Schematic Change

Reason: Protect manual reset pin.

Impact: None.

#1 Added pull-up resistor (R37) for signal "H1_A3".

Type: Schematic Change

Reason: Setup CS# signal externally.

Impact: None.

#19 Changed inductor (L1, L2, L3, L4, L6) from BKP0603HS121-T to MPZ0603S121HT000.

Type: BOM Change

Reason:EOL of component.

Impact: None.

#28 Added testpoint (TP1, ..., TP10).

Type: Schematic Change

Reason: Voltage and system monitoring improvement.

Impact: None.

#17 Removed track-it traceability pad S/N.

Type: Schematic Change

Reason: EOL of Component.

Impact: None.
