1. Close all Xilinx Programs
2. Power off TE0722
3. Bridge S25FL127S Pin 7 temporary with GND to change Boot Mode to JTAG Bode Mode only (See picture).
4. Power on TE0722
5. Disconnect you the GND bridge to wire from Pin 7
6. Open SDK
7. Pprogram Flash with valid Boot.Bin, if programming failed try again from step 1.

GND-Bridge to S25FL127S Pin 7

Chaning bootmode

The easies way to change the Bootmode pinstrap is temperary connection of SPI Flash Pin 7 to Ground. This pin Pin 7 is connected with Pullup-Resistor to 3.3V, to set FPGA in Quad-SPI Mode. To short Shorting this Pin with GND will enable JTAG Bode Boot Mode only.

Connect Pin 7 to one of the GND Pins only temporary for startup procedure(Temporary during powerup). After startup, Pin 7 trace is used to program the Flash. So you must disconnect your GND-bridge, so it must be floated (disconnected from ground).
