# Target specific options
[target.thumbv6m-none-eabi]
# Pass some extra options to rustc, some of which get passed on to the linker.
#
# * linker argument --nmagic turns off page alignment of sections (which saves
#   flash space)
# * linker argument -Tlink.x tells the linker to use link.x as the linker
#   script. This is usually provided by the cortex-m-rt crate, and by default
#   the version in that crate will include a file called `memory.x` which
#   describes the particular memory layout for your specific chip. 
# * no-vectorize-loops turns off the loop vectorizer (seeing as the M0+ doesn't
#   have SIMD)

  # Code-size optimizations.
  #   trap unreachable can save a lot of space, but requires nightly compiler.

# This runner will make a UF2 file and then copy it to a mounted RP2040 in USB
# Bootloader mode:
# runner = "elf2uf2-rs -d"

# This runner will find a supported SWD debug probe and flash your RP2040 over
# SWD:
