- Application: This sample code uses SPI and PDMA to access an external SPI Flash W25Q32.
- BSP Version: M251/M252/M254/M256/M258 Series CMSIS BSP V3.02.002
- Hardware: NuMaker-M252SD V1.1, SPI Flash W25Q32
This sample code uses SPI and PDMA to access an external SPI Flash W25Q32. First, user reads SPI Flash MID and DID information through SPI protocol. Then, erase SPI Flash. After erasing is done, repeatedly write data to SPI Flash and read back data for verification for 10 times. The data writing and reading to/from SPI Flash is also processed through PDMA.
