Hello @EthanChen 

According to the chapter 4.3 of the UM2237, the OTP is available on the STM32 MPUs and the STM32N6. About the OTP, on the STM32WL33, the OTP is a 1 Kbyte memory area (between 0x10001800 and 0x10001BFF). It should be accessible using the -w32 command (available on the part 3.2.5 of the UM2237).

Best Regards.
