[[PageOutline]]

Product Change Notifications (PCNs) are issued when errata or new revisions are released for Gateworks SBCs. Subscribe to the following Google group to get automatic PCN notifications.

There are two ways to subscribe:
 1. Send email to {{{pcn+subscribe@gateworks.com}}}
  - This does not require a Google account and will send PCN notifications as e-mails
 2. Join group at URL https://groups.google.com/a/gateworks.com/d/forum/pcn
  - This requires a Google account and provides a forum-like User Interface which provides a richer experience including history


PCN Events are triggered by several sources:
 1. Errata - [wiki:newport/errata Ventana] - [wiki:ventana/errata Ventana] / [wiki:laguna/errata Laguna]
 2. [wiki:sbcrevisions ECO - New Board Revision]
 3. [wiki:gsc#firmware GSC firmware updates] - changes to GSC firmware that ships on non revision locked board models by default
 4. Firmware image updates - changes to pre-built firmware image that ships on non revision locked board models by default (bootloaders + OS)
 5. Product End Of Life (EOL) notification (single board computers as well as popular OEM add-on cards re-sold through the store)

== PCN34 - April 2019 GPS Rollover  ==
 * Date: 03-28-2019 
 * PCN: On April 6, 2019 there will be a GPS rollover that could affect all GPS / Timing units in the world, regardless of manufacturer.

In addition to providing accurate location information, the Global Positioning System provides accurate timing information. It also includes the ability to transmit the proper date and time to a receiver by supplying the receiver with the current week and the current number of seconds into the week. This allows the receiver to translate the date and time into a more typical format – day, month, year, and time of day.

The field from the Satellite system that contains the week number is a 10-bit binary number. This limits the range of the week number to 0 – 1023, or 1024 total weeks.

GPS week zero started January 6, 1980. The 1024 weeks counter ran out and rolled over on August 21, 1999. The week counter then reset to zero, and it has been recounting ever since. The next time the counter will reach week 1023 and rollover to zero is on April 6, 2019.

April 6, 2019 is the 1024th week and unless a GPS module or application has already accounted for this, the date may not report accurately. If the application does not use the date or if there are other sources for the date outside of the GPS module, one may not be affected.

Notes for the following GPS devices:
 * Wi2Wi GPS - Used on Ventana Boards
   * 02120775: W2SG0008i - SiRF Star IV Chipset
   * Notes: Wi2Wi provided notice indicating that Qualcomm (formerly CSR) ran extensive simulator testing and that they saw no operational issues. 


 * u-blox GPS - Used on Newport and Custom Ventana Boards
  * 02120901: ZOE-M8Q-0
  * 02120830: EVA-M8M
  * Notes: As these are newer GPS chipsets, it is not expected they will face any issues. More information is available in the [https://portal.u-blox.com/s/ u-blox portal]


 * Trimble GPS - Used on Avila, Cambria and Laguna Boards
  * 02120512: Copernicus 63530-00 and Copernicus 58048-20
  * 02120619: Condor 68674-05
  * Notes: Recommended to update application code to accommodate for the week number change from the GPS module. Sample code is available by emailing Gateworks Support.


Customers using Gateworks BSPs with gpsd can address this within gpsd if using another time service. Customers not using the GPS time are not affected.

For systems that have no RTC, GPSD can provide the system time. If you manually set the system clock to a date in the current year before launching gpsd you will get the correct time (gpsd has some sanity check when setting system time).
