Overview

The TS-752 demonstrates the flexibility of a Technologic Systems SoM by connecting FPGA driven IO pins to relays, buffered digital inputs, buffered digital outputs, and RS-485 drivers. It also provides an RS-232 driver for the serial console. A TS-ENC750 with a TS-7500 or TS-7550 can provide a complete solution for many embedded applications.

Host-board Recovery

Although it is easy to get a TS-7500 board into an unbootable state during development if you botch a modification, it is equally easy to use the TS-752 to recover the default startup. To do so, place the JP2 jumper on the TS-752 and reset the board. In approximately 3 seconds, the board will have fastbooted to the TS-752 flash and present a shell prompt. To recover the default initrd and linuxrc, enter the command "spisave", remove the JP2 jumper, and reboot back to a restored to factory default configuration. The procedure is identical on the TS-7550 except you use the "nandsave" command since the TS-7550 has no SPI flash onboard.
