[predd.21]

Could you use C file functions? fopen, fread, fwrite, fclose ?

COPY  /b  a.bin+b.bin  c.bin

Most situations you actually want to convey meta-data like address and size, sort of thing an OBJECT FILE would do?

See also .DFU for a standardized/documented format for encapsulating binary data.

Use Srecord, or .....

 

In linker script of your aplication :

Create proper memory region for BOOTLOADER

and....

TARGET(binary)

INPUT(bootloader.bin)

OUTPUT_FORMAT(default)

TARGET(default)


SECTIONS

{

 .bootloader :

 {

 bootloader.bin (.data)

 . = ALIGN (0x4);

 } > BOOTROM

Explain for what, why not two hex merge?

[Radosław]

Some wrong character,   format correcly added lines in linker script, (maybe some unprintable sign was added)
