I needed a simple way to upload firmware, attach to repl over network and a way to run tests.
@tannewt encouraged me to make a PR of my attempt.

Show some board info:

$ ./cpboard.py feather_m0_express
Device: 239a:8023 on /dev/ttyACM0
Serial number: 9B81BE1A8413D405A413E263903150FF
os.uname:
  sysname: samd21
  nodename: samd21
  release: 6479cb080-dirty
  version: patchbase-dirty on 2018-06-01
  machine: Adafruit Feather M0 Express with samd21g18

$ ./cpboard.py 239a:8023
Device: 239a:8023 on /dev/ttyACM0
Serial number: 9B81BE1A8413D405A413E263903150FF
<...>

$ ./cpboard.py /dev/ttyACM0
Device: /dev/ttyACM0
Serial number: 9B81BE1A8413D405A413E263903150FF
<...>

Upload firmware:

$ ./cpboard.py -v feather_m0_express --firmware /tmp/firmware.uf2
Serial number : 9B81BE1A8413D405A413E263903150FF
Current version: patchbase-dirty on 2018-06-01
Reset to bootloader...done
Bootloader: {'header': 'UF2 Bootloader v1.21.0 SFHR', 'Board-ID': 'SAMD21G18A-Feather-v0', 'Model': 'Feather M0'}
Upload firmware...done
Wait for board...done
New version: patchbase-dirty on 2018-06-01

Run tests through the repl:

$ python3 run-tests --target=pyboard --device=feather_m0_express -d basics circuitpython
<...>

406 tests performed (12312 individual testcases)
401 tests passed
31 tests skipped: array_micropython async_await async_await2 async_def async_for async_for2 async_with async_with2 builtin_compile builtin_delattr builtin_pow3 builtin_pow3_intbig class_delattr_setattr class_descriptor class_new class_notimpl class_reverse_op class_store_class class_super_object exception_chain fun_name namedtuple1_cpython_compat nvm_not_present nvm_present object_dict object_new ordereddict1 ordereddict_eq parser struct_micropython subclass_classmethod
5 tests failed: blinky enumerate memoryview_gc struct1 struct2

Run tests through code.py:

$ CPBOARD_EXEC_MODE=disk python3 run-tests --target=pyboard --device=feather_m0_express -d basics circuitpython
<...>

### Expected
b'RuntimeError\n'
### Actual
b'CRASH'
FAIL  basics/gen_stack_overflow.py
Traceback (most recent call last):
<...>
sh.TimeoutException

I couldn't get the test run to finish. The board locks up so hard I have to flash-erase it. The tests did run yesterday, but not one week ago. Not sure what's going on here.

Removing the gen_stack_overflow test:

$ CPBOARD_EXEC_MODE=disk python3 run-tests --target=pyboard --device=feather_m0_express -d basics circuitpython
<...>

412 tests performed (12422 individual testcases)
400 tests passed
25 tests skipped: array_micropython builtin_compile builtin_delattr builtin_pow3 builtin_pow3_intbig class_delattr_setattr class_descriptor class_new class_notimpl class_reverse_op class_store_class class_super_object exception_chain fun_name gen_stack_overflow namedtuple1_cpython_compat nvm_not_present nvm_present object_dict object_new ordereddict1 ordereddict_eq parser struct_micropython subclass_classmethod

Attach to REPL over ssh:

ssh -t pi@cp.home 'screen $(./cpboard.py feather_m0_express --tty)'

This is a variant of pyboard.py aimed at Circuit Python boards.
It can emulate pyboard.py enough so it works with tests/run-tests.
@notro
tests: Point pyboard.py to tools/cpboard.py

This makes it possible to run-tests on the board itself.

Version 2

I accidentally commited my hack to remove execution of basics/gen_stack_overflow.py.

Lesson learned from #894 is that running tests using code.py can lock the board up so a flash erase or custom firmware is the only way out.

@dhalbert:

So perhaps we should have some way of forcing safe mode in case of really broken main.py/code.py or boot.py.
