The problem of BIN generated by STM32F051 being filled with 0 [Copy link]

When I was writing code for STM32F051, I used the operation __attribute__((at(0x800F800))) to locate the data at the specified address. However, only one BIN file was generated. I found that all the unused addresses in the middle were filled with 0, which made the entire BIN file very large and the download was very slow. The most important thing is that I cannot use the default FF to determine whether the data at a certain address is written, which is very inconvenient. However, when using STM32F103, there will be no such problem, but several separate program segments will be generated. Is there any way?

Please provide the project file. How is the BIN generated? It cannot be ruled out that it is a setting problem. Generate a HEX file and see if this phenomenon will not occur.

Change it to __attribute__((section("section_name"))) and then change the link script

Brother, have you solved the problem? I also encountered how to get rid of those filled 0s

My approach is to use two different projects to write
