Hi,

i am building the code for STM32WB55. I have enabled "Convert to binary file (-O binary)" and "Convert to Intel Hex file (-O hex)".

I got 2 files:

-bin file - 402MByte size

-hex file - 183kByte

As i can see, bin file has 62kByte of real data and rest of data are "0x00". How i can make just normal BIN file? Please help to find out :)

Hi Sergii,

I also ran into similar issue a while ago. Could you help check if your linker script contains MB_MEM2 with (NOLOAD)? If not, please add (NOLOAD) right after MB_MEM2 just like what you have for MAPPING_TABLE and MB_MEM1. Here is my record for your reference.

Regards,

Ethan

.HEX files can be sparse, .BIN files cannot.

Keil's tools will break this into multiple files under different directories if you have separate sections in the .ELF/.AXF
