Note: Pin functionality depends on the running CPLD Firmware, newest one is described here TE0713 CPLD

On-board LEDs

The TE0713-01 module has one LED which is connected to the System Controller CPLD. Once FPGA configuration has completed, it can be used by the user's design. 

...

System Controller CPLD (Lattice Semiconductor MachXO2-256HC, U3) is used to control FPGA configuration process. The FPGA is held in reset (by driving the PROG_B signal low) until all power supplies have stabilized.

By driving signal RESIN to low you can reset the FPGA. This signal can be driven from the user’s baseboard PCB via the B2B connector JM2 pin 18.

Input EN1 is also gated to FPGA reset, should be open or pulled up for normal operation. By driving EN1 low, on-board DC-DC converters will be not turned off.

DDR3L SDRAM

The TE0713-01 SoM has two 4 Gbit volatile DDR3 SDRAM ICs (U15 and U19) for storing user application code and data.

...

TE0713-01 is equipped with the FTDI FT600Q high performance USB 3.0-to-FIFO interface bridge chip.

FTDI doesn't support 245 Synchronous FIFO mode on TE0713, please use FT60X Chip Configuration Programmer to change Mode into  “Multi-Channel FIFO mode”.

SSTX_P and SSTX_N ar swapped on the PCB,this will be corrected automatically on link training on USB3
