Keil uses fromelf to generate bin files

1. The syntax format is as follows:

fromelf [options] input_file

[options] The options are as follows and can be used in combination, separated by spaces:

2. Usage process in Keil

1. Configure Output and generate executable files

aa is the executable file name, and the suffix is ​​axf. That is, after compilation, a file called aa.axf will be generated, and then a bin file will be generated from this file.

2. Configure User and generate bin file

In Keil's "User", you can set the run command. Here, it is set to execute the fromelf command after the compilation is completed. The following is an explanation:

C:KeilARMBIN40fromelf.exe --bin -o: The command means generating a bin file from the executable file.

D:1out33.bin: The path and file name of the generated bin file. 

D:1outaa.axf : The path and file name of the executable file.

After compiling, the 33.bin file will be generated (note that the path is variable).

3. Usage of $L, @L, L in fromelf

$L, @L, and L are used to specify the corresponding path or name.

1. L refers to the axf file path plus the file name.

2. $L refers to the file path of axf, not including the file name.

3. @L refers to the file name of axf, without the suffix of axf.

For example: generate D:1outaa.axf file, then

The content of L is: D:1outaa.axf

The content of $L is: D:1out (including the last "")

@L content: aa

So they can be used to form:

1. fromelf --bin -o "$L@L.bin" "$L@L.axf" means generating a bin file under the same file as axf.

2. fromelf --bin ".obj@L.axf" --output ".obj972.bin"
