Dear Valued Customer,

We are contacting you today to address U-Boot change for TS-4900 based products  from Technologic Systems.   The new version of U-Boot (dated Dec-21-2015) provides a bug fix and will begin shipping on new products after Jan 18, 2015.  This software is also available immediately on our FTP server.

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

The previous u-boot release ( Oct-14-2015) specified the Ethernet MAC address through a parameter that can cause older kernels to fail to load second ethernet's driver.  This Dec-21-2015 update corrects the issue by passing the second MAC address to Linux using the device tree.  The device tree implementation will not affect older drivers.  The latest Linux support retains support for either the device tree or parameter methods.

Users with the Oct-14-2015 u-boot release using the TS-4900 with either the TS-TPC-8390 or TS-TPC-8950 should update the u-boot to this image or update the Linux kernel to the latest released image on our webpage.
