Use srec_cat to join three binaries and fill holes
I have three binaries for specific memory addresses that I want to combine with srec_cat filling the holes with 0xFF.
- bootloader.bin —> 0x1000
- conf.bin —> 0x8000
- app.bin —> 0x10000
Memory map
|- pad w/ 0xFF -|- *bootloader* ~~~ pad w/ 0xFF -|- *conf* ~~~ pad w/ 0xFF -| - *app* ~~~|
0 0x1000 0x8000 0x10000
~~~ signifies a "fluid" boundary i.e. the binary to the left of it doesn't have a fixed size.
CLI arguments
I am a bit lost between the −fill, -binary and -offset options that I read about on http://srecord.sourceforge.net/man/man1/srec_examples.html#BINARY%20FILES. Is there a way to tell srec_cat to fill anything between 0x1000 and 0x8000 that is not occupied by bootloader.bin (regardless of what size the .bin actually has)?

Does this work:srec_cat bootloader.bin -Binary -fill 0xFF 0x00000000 0x00008000 conf.bin -Binary -offset 0x00008000 -o combined.bin -Binary?

I will try once the test environment is fixed but it "looks" wrong.bootloader.binneeds to be at offset 0x1000. Is the general idea to first fill from 0x0 to 0x10000 then cat bootloader at offset 0x1000, then cat conf at offset 0x8000 and then cat the app at the end?

No, as post process of what a 3rd-party Makefile produced ;-)

Nov 23 '18 at 10:56
I also tried the "first fill 0xFF up to 0x10000 and then overwrite" approach butsrec_catdoesn't support that:contradictory 0x00008000 value (previous = 0xFF, this one = 0xAA).
