The solution can be to use SFUD (Serial Flash Universal Driver), author armink, follow the MIT open source license agreement. Due to the large number of serial Flash types on the market, the specifications and commands of each Flash are different. SFUD can well avoid the differences in Flash and achieve unified management. You can also add partition management function (FAL), or use flash to implement database management (such as flash_db). In the future, we will further expand the development of SPI peripherals. ## ve file configuration [attach] 725501 [/attach] ## Program code [attach] 725511 [/attach] [attach] 725503 [/attach] [attach] 725504 [/attach] ## Test results [attach] 725505 [/attach]

AV32 uses VSCode as the development environment?
