Troubles with programmer
Make sure there are 2 converters in Device Manager before reading.
If there are two converters, this means computer and board succeed connectting. And if there is no converter, try another USB port or reinstall driver.
If you have any problems programming or flashing FPGA development board, it's suggested to use the programmer which can be downloaded at this page https://dl.sipeed.com/shareURL/TANG/programmer instead of what is installed with the IDE.

From the picture above we can know the path of this download file is fpga_project1/impl/pnr/fpga_project1.fs
The fpga_project1 is the project dictionary, the impl is generated by IDE, and the download is in the folder named pnr
The file whose extension name is fs is what we will burn into fpga
