Hello @willisk;

 

As mentioned in RM0486 the boot mode is determined by BOOT0 and BOOT1 pins, and one OTP word. You can boot source from flash when BOOT0=0 and BOOT1=0.

BOOT0 is a dedicated pin latched upon reset release.
The BOOT1 is a non dedicated boot pin. The BOOT1 value comes from BOOT1 pin (default
pin), or any other pin defined by BSEC BOOTROM_CONFIG10 - OTP_WORD19[28:21] =
dev_boot_port + dev_boot_pins.

 

I hope this help you.

Thank you.
