Dear Valued Customer,

We are contacting you today to notify you of New SPI Boot Flash Qualified on TS-4900, TS-7970, & TS-TPC-7990 with Updated Shipping Software.  The SPI Boot flash device used on these products went EOL and have been replaced with new sources.  Technologic Systems strives to find replacement memories that do not require software changes but in this case it was not possible.  This change will take effect as soon as Sept. 2018.  Please read below for details on how to determine if your software needs to be updated, and instructions for updating your software. Please contact us if you have any questions or concerns.

The affected products are: TS-4900, TS-7970, TS-TPC-7990, TS-TPC-8390-4900, TS-TPC-8950-4900

The SPI devices the above systems were designed with are no longer available.  Technologic Systems has qualified two replacement devices to reduce the impact of any potential EOL in the future.  Most applications will not be affected by this change unless they are manually accessing the SPI Boot flash or creating a custom u-boot.  An update has been made to the preloaded the image provided on the SD cards and on board flash by Technologic Systems.  All new cards and systems will be sent with the correct software preloaded.  

For all customers who use the image preprogrammed on these systems by Technologic Systems as is, no changes will be required. Just load your application code as usual on the new boards that you receive.

For any customers who build their own u-boot image to be loaded on the on board flash, or otherwise directly modify the SPI Boot Flash, please re-build your image using the files and information located at the following path:
