Shorten the Secure Boot Time in Traveo S6J3XXX Series MCUs - KBA222350

Version: *A

 

Question:

How can I shorten the secure boot time in Traveo™ S6J3XXX series MCUs?

 

Answer:

If SHE=ON, it is possible to shorten the secure boot time by setting the following registers:

  • Platform manual: BootROM software interface
  • SHE Secure Boot Mode Marker (BDR_SBMM)

0x0: Jump to user program before secure boot is completed

Except 0x0(default): Jump to user program after secure boot is completed

  • Debugger Connection Wait Enable Marker (BDR_DWEM)

0x292D3A7B: Debugger connection wait is disabled. It does not wait for debugger connection after the reset is released (included the state change from PSS mode to RUN mode). 

Except above value: Debugger connection wait enabled.
