Hello,

The error indicates that one or more of the new FW images are too big to fit in flash. Please start by confirming if both the new and old bootloader has the same start address in flash (this is not possible to change through DFU). You can find the default memory layout here if you don't use the "debug" bootloader: Memory layout
