4.1.5.2 Exporting the Flash Memory

The lower section of the Programming screen is used to export all of the flash memory from the device (see Figure 4-5).

  1. In the first lower box, press the Browse button and enter a .bq.fs filename. This contains the encrypted firmware changes and updates.
  2. In the Path for combined .bq.fs, press the Browse button and enter a .bq.fs filename that defers from the name above (for example, filename_combined), see example Figure 4-5. The combined .fs file contains the encrypted FW and user specific settings to be uploaded in production.
  3. In the Path for encrypted .bq.fs, press the Browse button and upload the encrypted bq.fs file provided from ti.com. This encrypted file is the default .bq.fs that the user can download from ti.com.
  4. Press the Read FS from Data Memory to save the Flash memory contents to the file. Wait for the Operation executed successfully message at the left bottom corner of the BQStudio screen.
