Usually debug printfs are not on in embedded targets.

I see it is usually not included, but Renesas e2Studio has by default. I was assuming nice to enable in the sample project.

I agree, and I am in favor of having debug in the example application. I don't like debug prints in the bootloader code, for safety and code size reasons. All the data you print are available in the application space as well and can be printed after the application has been staged, avoiding to bring in kilobytes of libC code + device drivers in your bootloader code.

I see your current bootloader partition is 64KB, I wonder if it can be made smaller.

Hi @kojo1 what is the status on this one? We have recently received some enquiry about this port.
