Getting started to hardware description language and FPGA
I decided to learn a little bit of Verilog and FPGA.
A nice place to start reading about Verilog is this site:
https://www.asic-world.com/verilog/index.html
https://mjseemjdo.com/2021/03/28/the-15-fpga-with-20-000-luts/
Of course you can use Verilator to start with a simulator, but soon or later you will want to buy a board. I decided to start with the Sipeed Tang Primer 20K board because it is low cost.
Writing 0xFF into files using dd command
dd if=/dev/zero bs=1M count=100 | tr '\000' '\377' > file

Getting started to nanoCH32V203 board
Few days ago I received a low cost nanoCH32V203 that I bought from Aliexpress and today I decided to test it.
Unfortunately the official board github https://github.com/wuxx/nanoCH32V203 doesn’t have a flashing tool for Linux, but I found this Rust https://github.com/ch32-rs/wchisp tool for CH32V208 and decided to test it with CH32V203:
