Regarding your question about the "Renesas Flash Development Toolkit (FDT) v4.09" and its support for the "H8/3334 HD64F3334CP16" chip model, you would need to verify the compatibility of this specific chip with the toolkit version. I recommend checking the official Renesas documentation or contacting Renesas support for confirmation on compatibility, as they can provide the most accurate information about supported devices and any necessary updates or patches.
