The following procedure can be used to cause the part to reboot and bypass the programmed image.
Note: this procedure applies to all parts except MT9V126/7/8.

  1. Start DevWareX and "Probe" to identify the part. When the "Startup Wizard" dialog appears, deselect all options and select "Finish".
  2. Set Register 0x20 bit 5 to 1; this will disable access to the Flash/EEPROM.
  3. Toggle Register 0x10 bit 0 on/off; this preforms a soft reset on the sensor.
  4. Verify that Register 0x1C = 0x3000; indicates a successful reboot.  Leave DevWareX running.
  5. Run FlashTool and attempt to program the Flash/EEPROM.
  6. Select "Verify" to ensure the binary was programmed correctly.
  7. Go back to DevWareX and clear Register 0x20 bit 5 and toggle Register 0x10 bit 0 on/off.
  8. From the Command Menu item, select "Check Sensor State", then select "Play" - you should see a stream image.

7 Clearing Out Flash/EEPROM

An "empty" binary image is provided to clear-out the Flash/EEPROM device.

It is located in the based "flashtool" folder, "blank.bin".  The binary is actually full of 0xFF, which the FW will recognize as unprogrammed.

Follow the regular programming settings, and select blank.bin as the file to program.
