Updating The Os - Denso BHT-400-CE Reference Manual

12. Updating the OS

The system can be updated (version update) by creating and executing the update applications discussed in the
procedure below while Windows CE is running.
Update method using RAM
(1) Call up the PwrMng.Shutdown(PwrMng.EN_SHUTDOWN_MODE.SYSMODIFY) method and reboot the
BHT (*1).
(2) After rebooting, a "SysModify" directory (RAM disk) is created. Copy the OS file to this directory.
(3) Specify the update filename in the SysModification.FileName property.
(4) Call up the SysModification.Execute method to update the OS.
(5) The power turns OFF automatically after the update procedure is complete (The BHT cold boots and the
registry is initialized the next time the power is turned ON.)
Update method using CF memory card
(1) Call up the PwrMng.Shutdown(PwrMng.EN_SHUTDOWN_MODE.SYSMODIFY) method and reboot the
BHT (*1).
(2) Save the OS file to the CF memory card and insert the card in the BHT-400 CF slot.
(3) Perform steps (3) to (5) above for the "Update method using RAM".
(*1) After rebooting, the RAM usage allocation is decreased by approximately 32 MB in order to ensure that
the system secures approximately 32 MB for updating the OS.
