Compile the give file name to binary object file (see below.)
|
|
|
|
Output will be elf object file of the same name, with .o, in root directory.
|
|
|
|
Note: Because of Bug #13, you need to run "ld -N file.o" on the file, before
|
|
executing it. This can be done on a mac by installing a cross linker
|
|
(brew install arm-linux-gnueabihf-binutils), or on the target arm machine.
