Download Binaries using JLink SWD

QuickLogic Thing Plus supports loading and testing stand-alone eFPGA design or eFPGA + M4 MCU design, using SWD standard tool such as Segger’s Jlink SWD or OCD. Below are the instructions for system with Windows 10 OS with Segger Jlink pod.

What you need

• Laptop or PC with Windows 10
• Segger Jlink pod and PC connecting USB cable
• Segger Jlink adapter to 10-pin connector and cable
• QuickLogic Thing Plus board and micro USB cable

Download stand-alone FPGA binaries instructions

• Disconnect QuickLogic Thing Plus power; if USB-to-Serial cable connected to the board, remove the connection from PC
• Install shunts at QuickLogic Thing Plus J2 and J3
• Connect micro USB cable from QuickLogic Thing Plus to PC
• Connect 10-pin cable to QuickLogic Thing Plus connector J6; check connector key for correct alignment
• Press reset button
• Open CMD console
• Type: “Jlink.exe -device cortex-m4 -If SWD -speed 4000 -commandFile "Jlink script"”

Note:

• Jlink.exe: Link commander – include reference to the location of executable
• Jlink script: output file symbiflow for EOS S3 FPGA binaries
• Refer to Jlink Commander for more additional information

Download FPGA binaries + M4 MCU binaries instructions

• Disconnect QuickLogic Thing Plus power; if USB-to-Serial cable connected to the board, remove the connection from PC
• Install shunts at QuickLogic Thing Plus J2 and J3
• Connect micro USB cable from QuickLogic Thing Plus to PC
• Connect 10-pin cable to QuickLogic Thing Plus connector J7; check connector key for correct alignment
• Press reset button
• Open CMD console (#1)
• Launch Jlink commander (i.e. type “Jlink.exe”) and follow the on-screen instructions to connect to QuickLogic Thing Plus M4 target
• Execute the followings in Link Commander console
  • Type: “r” to reset the EOS S3
  • Type: “loadbin qt_helloworldsw.bin 0x0”
  • Type: “r”
• Open another CMD console (#2)
• Type: “Jlink.exe -device cortex-m4 -If SWD -speed 4000 -commandFile "Jlink script"”

Note:

• Jlink.exe: Link commander – include reference to the location of executable
• Jlink script: Symbiflow’s output for EOS S3 FPGA binaries
• Refer to Jlink Commander for more additional information
• Return to console #1; type: “g”; the M4 binaries in M4 SRAM will start to run and the eFPGA is configured
