Likely a change in the command line interface of EDBG broke the
`make reset` integration. This adds the missing flag.
Note: Since the binary is build on demand with our build system, we
can in fact rely on every using the same version of EDBG. Hence,
we don't need to be backwards compatible with the flag.
Prepare for handling pkg state with files. So it requires having the
path defined before declaring targets. In addition, it cleans up the
old git-download target.
The lastest version of edbg solves a double-reset issue that was
hindering testing (see #11125 and https://github.com/ataradov/edbg/issues/77)
It also adds support for SAMR34 and SAMR35, needed by @dylad for MCU
port.
update to the current lastest version of EDBG to allow user to reflash a bricked board due to sleep mode or wrong clock assignment. this avoid the use of Atmel Studio to erase flash.
