Probably the newbie friendlyness is to be blamed...

Anyhow, I have a branch for on-hardware CI testing, where I've added 
another flash target that doesn't have the dependency. Find the commit 
here [1].

I remember that (years ago) I thought that this would be a bad idea, but got
overruled. IIRC the reasoning was that otherwise `make flash` may fail.

Does it actually recompile?

The flash target in Makefile.include depends on the "all" target, 
ensuring that the build is up-to-date. I guess at some point we thought 
that is a good idea.


Removing that dependency stops the forced update.

Hi,

In general this should not be the case. I'd imagine one of the packages messes 
up the build system's dependencies. Hard to say without seeing the project.

Cheers,
Ludwig

[riot-devel] flash command without compiling

[Jose Alamos]

Dear RIOTers,

I noticed the 'make flash' recompiles everything before flashing. What's
the reason behind this?

I'm working with some packages that require some time to configure/compile,
and everytime I run 'flash' I have to wait the whole process to finish. I
cannot even flash 2 boards at the same time because the compile process is
concurrent.

As always, any ideas would be appreciated :)

Cheers!
