Introduction

...

  • STIG Memory Bank (no support in the driver)
  • Indirect Non-DMA read and write support.

Supported Flash parts

  • Micron (512Mb, 1Gb and 2Gb)

Test cases

  • xospipsv_flash_polled_example - This example writes to flash in STIG mode and reads back the data in DMA mode, it runs in polled mode.
  • xospipsv_flash_intr_example - This example writes to flash in STIG mode and reads back the data in DMA mode, it runs in interrupt mode.
  • xospipsv_flash_non_blocking_read_example - This example writes to flash in STIG mode and reads back the data in DMA mode(using non-blocking API's), it runs in polled mode.
