Changes
#1 Added pin header (J4) assembly option and resistor (R30) to enable FPGA 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.
#2 Added diode (D1) between signals "INIT" and "PROG_B" for FPGA configuration control.
Type: Schematic Change
Reason: Improve FPGA configuration handling.
Impact: None.
#3 Add protection diode D3 to U8.3 (#MR input).
Type: Schematic Change
Reason: Avoid voltage high-signal-state at U8 manual reset pin 3 without powered supervisor.
Impact: None.
#4 Added pull-up resistor (R29) to #RESET signal for Flash (U7).
Type: Schematic Change
Reason: Use external pull-up resistor.
Impact: None.
#5 Added pull-up resistor (R31) to #WP signal "SPI-DQ2" for Flash (U7).
Type: Schematic Change
Reason: Use external pull-up resistor.
Impact: None.
#6 Added capacitor (C22) for PROGRAM_B_0 signal "PROG_B" for FPGA (U1).
Type: Schematic Change
Reason: Improve reset signal handling.
Impact: None.
#7 Added additional decoupling capacitor (C24).
Type: Schematic change
Reason: Improve noise immunity.
Impact: None.
#8 Changed ferrite bead location (L6).
Type: Schematic change
Reason: Improve power rail filter for power rail "AVCC".
Impact: None.
#9 Changed ferrite bead (L1, L2, L6) from BKP0603HS121-T to MPZ0603S121HT000.
Type: BOM Change
Reason: EOL of component.
Impact: Increase current capability, decreased DC resistance and minor changes in electrical characteristics.
#10 Changed resistor (R3, R9, R13, R18, R20, R21, R72) from 5.6 kOhm to 2.2 kOhm.
Type: BOM change
Reason: BOM Optimization.
Impact: None.
#11 Changed resistor (R7) from 10 kOhm to 2.2 kOhm and added 2.4 kOhm resistor (R32).
Type: BOM change
Reason: Improve reset circuit voltage divider accuracy.
Impact: None. Improved reset handling.
#12 Changed resistor (R4, R15) from 2 kOhm to 330 Ohm.
Type: BOM change
Reason: Follow AMD recommendation.
Impact: None.
#13 Changed capacitor (C21) from 47 µF to 100 µF and added additional decoupling capacitor (C33 ... C35).
Type: Schematic change
Reason: Follow AMD recommendation.
Impact: None.
#14 Added test point (TP1 ... TP15).
Type: Schematic Change
Reason: Improve measurement and debugging options.
Impact: None.
#15 Added UKCA- and RoHS logo.
Type: PCB Change
Reason: Improve product classification identification.
Impact: None.
