I am using VsCode with PlatformIO with a very simple program. It compiles correctly and produces working elf and hex files.
However, unless pio states that it checkes the sizes it does not output anything.
my configuration is the following
[env:release]
platform = atmelavr
board_build.mcu = atmega168A
board_build.f_cpu = 8000000L
running the build it just outputs:

even with running it with -v it shows not much more information

Manually calling avr-size from the the downloaded packages correctly shows the info.
Any suggestions how to solve this?
Adding an explicit board config item to the config seems to fix that problem.
[env:release]
platform = atmelavr
board = ATmega168
board_build.mcu = atmega168A
board_build.f_cpu = 8000000L
