DA1469x Adesto AT25SL321 Flash driver

Example description

This example downloads and runs FreeRTOS Retarget project with the Adesto AT25SL321 QSPI Flash attached to the DA1469x device.

HW and SW configuration

  • Hardware configuration

    • This example runs on The DA1469X Bluetooth Smart SoC devices.

    • The Pro Development kit or USB is needed for this example.

    • Connect the Development kit to the host computer.

    • The development kit needs to have the flash replaced with Adesto AT25SL321.

  • Software configuration

    • This example requires:

    • SmartSnippetsStudio 2.0.12 or newer

    • SDK10.0.8.105 or newer

    • SEGGER J-Link tools should be downloaded and installed.

How to run the example

Initial Setup

  • Compile the QSPI target version of the project.

  • Move the file qspi_at25sl321.h found under {project_root}/config, to {SDK_root}/sdk/bsp/memory/include folder

  • In sdk/bsp/memory/src folder, automode.c file find the following snippet

    #if (FLASH_AUTODETECT == 1)

    where the drivers are included and include driver qspi_at25sl321.h. Additionally right after that, where static const qspi_flash_config_t* flash_config_table[] is defined, add the configuration object to the array by adding … &flash_at25sl321_config,

  • Recompile the uartboot, libprogrammer and cli_programmer projects with the added flash driver files.

  • Program the device and reboot

  • Use your preferred terminal to the serial port (FTDI lower index port) with the following parameters

    • baudrate: 115200

    • data: 8 bits

    • stop: 1 bit

    • parity: None

    • flow control: none

  • The terminal displays the “#” characters every second.

Flash Configuration Setup

Under {SDK_root}/utilities/python_scripts/qspi folder, edit file flash_configurations.xml and add the following configuration.

  <configuration name="Adesto AT25SL321">
    <flash_size>0x400000</flash_size>
    <flash_burstcmda_reg_value>0xa8a000eb</flash_burstcmda_reg_value>
    <flash_burstcmdb_reg_value>0x00000066</flash_burstcmdb_reg_value>
    <flash_write_config_command>0x31 0x02 0x07</flash_write_config_command>
  </configuration>

Pick the ‘program_qspi_config’ option before burning any firmware to the new device. In the subsequent windows make the following choices.

  • Product ID: DA1469x-00

  • Flash: Adesto AT25SL321

  • active_image_address: 0x2000

  • update_image_address: 0x2000

Known Limitations
