flexspi_psram_dma_transfer#
Overview#
The flexspi_psram_dma_transfer example shows how to use flexspi driver with dma:
In this example, flexspi will send data and operate the external PSRAM connected with FLEXSPI. Some simple flash command will be executed, such as Read Data and Write Data. Example will write/read through the whole chip, using DMA transfer way.
