TS-7680 FPGA Bitstreams

From Technologic Systems Manuals

The FPGA has the capability to be reloaded on startup and reprogram itself with different configurations. The FPGA does have an internal configuration is stored, however the FPGA SRAM can be reloaded at bootup to provide an updated FPGA logic, or other custom implementations. U-Boot will automatically load the bitstream located at /boot/ts<model>-fpga.vme on the Debian root at startup.

The FPGA can be updated to the latest revision by booting to Debian and running:

cd /boot/
wget ftp://ftp.embeddedarm.com/ts-arm-sbc/ts-7680-linux/binaries/ts-bitstreams/ts7680-fpga.vme

The FPGA is loaded in to the FPGA SRAM on every poweron, so this file will need to exist for all future boots.


An FPGA revision changelog can be found in the Revisions and Changes section.
