If you try to update to a larger bootloader, then you will get an error that the image is to large. This is because theMBR looks up the bootloader start address, which is written to one of the UICR registers which is set when you initially flashed the device.

It is possible to change modify the UICR register, as described in this answer, but it should only be used as a last resort as this approach could lead to the device being bricked if a power failure occurs.

There is no hard limit, except the limit due to the flash size on the hardware.

We realized that we had the debug version of the Bootloader, and it worked after we removed the flags.

Regardless, we have a general question. Is there a hard limit on the bootloader size? Let's suppose we do a bootloader update that is significantly bigger than the current one. Is it possible to update that?

@emdi is correct, there is not enough space for the new bootloader. Did you change the memory settings or change the optimization level in the new bootloader project ?

Seems like you don't have space in flash.
