WSL has been very useful as a Linux environment running on Windows 10. One problem for WSL is, however, that it is installed to the C drive by default. It would easily take up over 10 GB of space after installing some programming tool chains on it. Recently, my C drive was once again filled by software that can only be installed on C drive. As I browse for files to remove, I found out that my WSL installation was taking 15 GB of storage! After some online search, I managed to move my WSL file system out of C drive. Here is a link to the solution I referred to. I will also briefly talk about it here. Move WSL File System ::: tip Note that all commands below should be run in PowerShell ::: First, list your WSL distros (wsl -l): PS C:/> wsl -l Windows Subsystem for Linux Distributions: Ubuntu20.04 (Default) Ubuntu-20.04 Take note of the name of the distro you want to move (E.g. Ubuntu-20.04) Export the distro to a tar file (wsl --export <distro-name> <path-of-tar-file>). E.g.: PS C:\> wsl --export Ubuntu-20.04 E:\ubuntu-wsl.tar After the export finishes, import the tar file to your desired location (wsl --import <distro-name> <path-of-desired-location> <path-of-tar-file>). E.g.: PS C:\> wsl --import Ubuntu20.04 E:\WSL\Ubuntu20.04 E:\ubuntu-wsl.tar After this is done, test the new distro with wsl -u <username> -d <distro-name>. E.g.: PS C:\> wsl -u rochor -d Ubuntu20.04 If it works as intended, you can then safely remove the original distro (wsl --unregister <distro-name>). E.g.: PS C:\> wsl --unregister Ubuntu-20.04 PS C:\> wsl -l…

Introduction The Sipeed Tang Nano (sometimes also refered to as Lichee Tang Nano) is a cheap but powerful FPGA development0 board that features the GW1N-LV1QN48C6/I5 chip from Gowin. It costs as little as USD4.90 or CNY34.90. The Gowin GW1N chip has 1152 LUT4, 864 FF, 72Kbit B-SRAM, 96Kbit user flash and 1 PLL. The board also has an onboard 24MHz crystal. The board has 64Mbit QSPI PSRAM, 36 I/O Pins, 1 RGB LED, 2 push buttons and a 40-pin LCD interface with on-board backlight driver circuit. It has a built-in JTAG downloader so you can download to the chip by simply connecting the computer to it through a USB-Type-C cable. In this article, we will go through the basic steps of how to set up a development environment for the Tang Nano. Download and Install the official Gowin IDE For now, we need the official Gowin IDE to work with the Tang Nano board. Download the IDE from here. Find the links shown in the figure below and download the latest version for your operating system (Windows or Linux). To install the IDE, Windows users need to unzip and run the installer and follow the step-by-step instructions. Install the driver if not already installed. For Linux (I have only tested it on Ubuntu, but other common Linux distros should also work) users, just extract the files to any location. Configure License Open the IDE. Windows users can select it from the Start Menu and linux users can run the gw_ide executable file under the .../IDE/bin/ directory (make sure you have…
