Hex file: adding dummy bytes

[Sanjay8344]

within the SM32 cube Ide After creating a hex file, I noticed that some lines had less data than others due to linker separation. How can I use the stm32 cube ide to add dummy bytes to the memory?

Thats "normal" in a (Intel-)HEX file.

>to add dummy bytes to the memory

Why ?

[Sanjay8344]

In order to extract data from a hex file and write it into memory while working on the bootloader, I must do a remote update. In order to accomplish this, I must write 0xffff in a location where there is less data on the specific lines. I now know that the linker script can be used to change it but not How to do that.
