Hello @EddiePark,

 For more information about the booting flow you can check Chapter 30 of the reference manual [page 1225, S32G2 Reference Manual, Rev. 8, February 2024]:

In particular please check sections 30.3.2 Boot from fuses and RCON,30.3.2.1 Boot from fuses and 30.3.2.4 Selection of boot from fuses or boot from RCON [pages 1227 and 1228]:

Please also check Chapter 63 On-Chip One Time Programmable (OCOTP) Controller [page 3358]:

For an example program you can check Ocotp_Ip_Example_S32G274A_M7 or Ocotp_Example_S32G274A_M7, for the RTD or MCAL/AUTOSAR API respectively. Please be careful when executing the code, as you know the fuses are one time programable.

If you have more questions about this topic please let me know.
