-- `<offset>` is the offset to the base address that will be applied to the generated hex file. Without this option, the offset is 0x0, so automated programming tools will attempt to load the hex file starting at address 0x0, which is likely not the desired behavior. The <offset> parameter should correspond to the base address of the NVM partition used by wolfHSM in the device's address space.
