Generating Intel Hex Files with a given Length using srec_cat

The ‘standard’ binary files for many tools are S19, binary or Intel Hex files. Especially for S19 and Intel Hex it can be useful to control the amount of data per line. By default, the GNU objcopy creates files with a line length of 44 characters:

default objcopy binary file line length

default objcopy binary file line length

But it is possible to have Intel Hex files with an custom line length using the SRecord utility, and this is what this article is about.
