[[PageOutline]] = Newport Errata The below errata only affects certain models and certain revisions. Please contact support@gateworks.com with any questions. [=#np1] == NP1 Occasional failure to detect GigE PHY on GW6300-B Issue: * The TI DP83867 PHY's are occasionally not detected on board power-up. This is caused by the MDIO voltage rail inappropriately tied to 3.3V instead of the desired 2.5V as well as the lack of a RST# signal going to the PHY's which should not be necessary per the datasheet but has been found experimentally to be required. Upon failure the Boot Firmware will fail to detect the PHY on the MDIO channel and the network device will not be present. Resolution: * This is resolved on PCB 02210153-02 (GW630x-C) (Rev C) * This is resolved via re-work (cut/wire) on GW630x-B.3 (Rev B.3) Affected Product: * GW630x-B (PCB 02210153-01) [=#np2] == NP2 Reverse Polarity voltage protection Issue: * Reverse Polarity voltage protection on the power input to the board is not available. Powering the board with Vin polarity reversed will result in board damage. Resolution: * Reverse Polarity voltage protection will be added. Affected Product: * GW640x-A (PCB 02210154-00) * GW630x-B/C (PCB 02210153-01, PCB 02210153-02) * GW610x-A (PCB 02210151-00) Fixed in: * GW640x-B (PCB 02210154-01) * GW630x-D (PCB 02210153-03) * GW610x-B (PCB 02210151-01) [=#np3] == NP3 CPU Temperature Sensor Issue: * The temperature sense logic of the CN80XX Voltage Regulator Module (VRM) is not properly calibrated resulting in unexpected temperature readings (Cavium CN80XX ID 32702). As a result, the CPU Temperature is not obtainable from the SoC in current silicon (Pass 1.0, 1.1, 1.2) Resolution: * An external temperature sensing device will be added using the CN80XX thermal core diode junction to provide CPU temperature sense capability. Affected Product: * GW640x-A (PCB 02210154-00) * GW630x-B/C (PCB 02210153-01, PCB 02210153-01) Added in: * GW640x-B (PCB 02210154-01) * GW630x-D (PCB 02210153-03) [=#np4] == NP4 eFUSE Program-ability Issue: * The One-Time-Programmable (OTP) eFUSE banks available on the CN80XX require external circuitry to program. Resolution: * External circuitry will be added to boards to allow programming outside of a test fixture. Affected Product: * GW640x-A (PCB 02210154-00) * GW630x-B/C (PCB 02210153-01, PCB 02210153-01) Added in: * GW640x-B (PCB 02210154-01) * GW630x-D (PCB 02210153-03) [=#np5] == NP5 Fan Tachometer improvements Issue: * Certain fans either drive the TACH signal to an inappropriate voltage level for the GSC or produce too much of a load for the GSC to accurately measure TACH pulses. Resolution: * A FET added to the TACH signal provides voltage protection and isolates the load of the fan allowing the GSC to properly count TACH pulses. The TACH drive on the fan must be capable of sinking 5mA of current to assert the pulse to the GSC. Affected Product: * GW640x-A (PCB 02210154-00) * GW630x-B/C/D (PCB 02210153-01, PCB 02210153-02, PCB 02210153-03) * GW610x-A (PCB 02210151-00) Resolved in: * GW640x-B (PCB 02210154-01) * GW630x-E (PCB 02210153-04) * GW620x-A (PCB 02210152-00) * GW610x-B (PCB 02210151-00) [=#np6] == NP6 GW640x Ethernet LED's non-functional Issue: * The GW640x QSGMII ports do not have their RJ45 (J22) and SFP jack (J13) LED's connected properly. The RJ45 LED's will never illuminate and the SFP LED's will behave inconsistently. The RGMII LED's on J21 are connected and do behave as designed. Resolution: * Network connector LEDs are fixed on future board revision Affected Product: * GW640x-A (PCB 02210154-00) Fixed in: * GW640x-B (PCB 02210154-01) [=#np7] == NP7 CAN not functional Issue: * The CAN transceiver is missing a pull-down on its STBY signal rendering it unable to send/recv. Resolution: * Properly terminate the STBY signal Affected Product: * GW6404-A (PCB 02210154-00) * GW6304-A/B/C/D (PCB 02210153-00, PCB 02210153-01, PCB 02210153-02, PCB 02210153-03) * GW6204-A (PCB 02210152-00) Fixed in: * GW6404-B.1 (PCB 02210154-01) * GW6304-E (PCB 02210153-04) * GW6204-B (PCB 02210152-01) [=#np8] == NP8 GSC RTC Drift Issue: * The GSC may experience oscillator faults which cause RTC resets drift over time. Resolution: * Upgrade to the [wiki:gsc#GSCUpdates latest GSC firmware] (v55 or greater) to eliminate the GSC resets. * The GSC crystal and capacitors have been updated to resolve the oscillator faults and greatly reduce RTC drift. Affected Product: * GW610x-A/B (PCB 02210151-00, PCB 02210151-01) * GW620x-A/B (PCB 02210152-00, PCB 02210152-01) * GW630x-B/C/D/E (PCB 02210153-01, PCB 02210153-02, PCB 02210153-03, PCB 02210153-04) * GW640x-A/B (PCB 02210154-00, PCB 02210154-01) Added in: * GW610x-B.1 (PCB 02210151-01) * GW620x-B.1 (PCB 02210151-01) * GW630x-C.2/D.3/E.1 (PCB 02210153-02, PCB 02210153-03, PCB 02210153-04) * GW640x-B.1 (PCB 02210151-01) [=#np9] == NP9 Reverse Current Susceptibility Issue: * While 'reverse polarity' protection exists on most Gateworks boards allowing Vin polarity reversal to not damage boards, 'reverse current' protection does not exist on certain boards which could cause board damage under specific situations. A condition which would allow for such damage is if a board was connected to a Power-Over-Ethernet supply (regardless of if it is enabled for Active PoE) as well as at the same time powered with a lower voltage supply connected to board input power (ie barrel jack or 2-pin Vin aux connector). For example powering a board with 48V PoE at the same time as a 24V supply on the barrel jack would cause power to flow from the higher PoE positive rail back through the supply connected to the barrel jack which could put the supply in an over-current failure mode that sinks current directly to ground damaging the Gateworks board. Resolution: * Do not connect Ethernet PoE and the DC Power input (barrel jack or header) at the same time.
