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

Change current directory to firmware example (here HydraUSB3_Blink_ULED)
- cd ~/hydrausb3_fw/HydraUSB3_Blink_ULED
Clean and build the firmware example
- make clean all
The flashable firmware with wch-ch56x-isp (*.bin) is available in ~/hydrausb3_fw/HydraUSB3_Blink_ULED/build/HydraUSB3_Blink_ULED.bin
