  • Follow all the steps including "Now MSYS2 is ready for you. You will probably want to install some tools and the mingw-w64 GCC to start compiling:"
    • pacman -S --needed base-devel mingw-w64-x86_64-toolchain git

• Start mingw64

cd ~
git clone --recursive https://github.com/hydrausb3/hydrausb3_fw.git

• Launch MounRiver Studio
  • Select a directory workspace (use the default one)
  • Select Menu File => Import...
    • In Import Windows choose General => Existing Projects into Workspace
      • Select Next >
      • A window Import Projects appears
        • Click on Browse near "Select root directory:" and choose hydrausb3_fw directory
          • Click on Select Folder
        • Select the different project(s) you want to import (in Projects)
        • Click on Finish
  • Project Explorer now show all imported projects
    • Left Click on any project (or choose multiple projects too) to highlight them
    • Right click on the highlighted project and choose Build Project or Build Projects
    • If all is ok the project shall build fine and display in Console "Build Finished. 0 errors, 0 warnings."

• Install pkg-config and libusb-1.0-0-dev
  • pacman -S mingw-w64-x86_64-pkgconf mingw-w64-x86_64-libusb

• Start mingw64

cd ~
git clone --recursive https://github.com/hydrausb3/wch-ch56x-isp.git
cd wch-ch56x-isp
make

1. On HydraUSB3 (disconnect any cable/power supply) and add a Jumper on Flash Mode P3
2. Connect “USB A Male to USB A male cable” to HydraUSB3 then the other side to PC(USB2 or USB3 port)
3. The PC shall detect the WCH CH569W Bootloader (enumeration with USB2 HS)
   • Download & Execute Zadig 2.7
     • Install driver "WinUSB" with Zadig for the USB ID 4348 55E0
       • Note after 10s of inactivity the bootloader exit and run the program
         • You can just reset the board to re-enter in bootloader by pressing(1s) & releasing 3V3 DISABLE button(at left of USB3 connector)
   • You can check it is well recognized with windows PowerShell with command Get-PnpDevice -PresentOnly | Where-Object { $_.InstanceId -match '^USB\\VID_4348' } | Format-List which shall find HardwareID : {USB\VID_4348&PID_55E0&REV_2700, USB\VID_4348&PID_55E0} Manufacturer : WinChipHead PNPClass : USBDevice Present : True Service : WinUSB
   • Note after 10s of inactivity the bootloader exit and run the program
     • You can just reset the board to re-enter in bootloader by pressing(1s) & releasing 3V3 DISABLE button(at left of USB3 connector)
4. Launch(quickly to avoid 10s timeout) wch-ch56x-isp to flash(and verify) the hydrausb3_fw example (here HydraUSB3_Blink_ULED)
   • ./wch-ch56x-isp -v flash ~/hydrausb3_fw/HydraUSB3_Blink_ULED/obj/HydraUSB3_Blink_ULED.bin
5. On HydraUSB3 Remove the Jumper on Flash Mode P3
6. On HydraUSB3 Press(1s) & Release the 3V3 DISABLE button(at left of USB3 connector) to reset the board

• The HydraUSB3 board shall execute the HydraUSB3_Blink_ULED firmware example by blinking the ULED
  • Note: If you press UBTN the ULED blink very fast
