Hi,

Can you comment a bit on what kind of exception you're getting?

Thanks,
Bogdan

from mbed-os.

When i print sys.exc_info():
From serial.sendBreak() i get

(<class 'termios.error'>, error(32, 'Broken pipe'), <traceback object at 0x219bd88>)

From serial.setBreak(False) i get

(<type 'exceptions.IOError'>, IOError(32, 'Broken pipe'), <traceback object at 0x21ac320>)

from mbed-os.

Try adding a 'raise' as the first statement after 'except:'; this way, the error will be thrown again and we'll be able to see the full traceback (hopefully).

from mbed-os.

By adding the raise i only get:

>>> BUILD PROJECT: BASIC (LPC1549, GCC_ARM)
Image: /home/user/projects/mbed/build/test/LPC1549/GCC_ARM/MBED_A1/basic.bin
[ERROR] (32, 'Broken pipe')
[user@localhost mbed]$ 

from mbed-os.

Add a '-v' to make.py and retry please.

Thanks. I won't merge this yet, I'd like to try to understand where that
error comes from first.

@chrta: I've reproduced your problem:

przemek@mbedci:~/mbed/workspace_tools$ python make.py -t uARM -m LPC1549 -d /media/usb1/ -s /dev/ttyACM1 -n MBED_A1

>>> BUILD PROJECT: BASIC (LPC1549, uARM)
Image: /home/przemek/mbed/build/test/LPC1549/uARM/MBED_A1/basic.bin
[ERROR] (32, 'Broken pipe')

I will take a look at this issue and fix it. No need for your to do pull request because I will probably update other scripts with proper sendBreak function :)

BTW, make.py script is obsolete, we will use new one (singletest.py). I'm writing Wiki how to use new script. I will try to publish this info next week.

@chrta I've added your correction to make.py and added similar function for host_test Mbed base class. In near future make.py will be removed from workspace_tools and replaced by singletest.py script which is proper script to run tests (it support host_test philosophy - supervise test using separate process).

Same make.py command after fix:

przemek@mbedci:~/mbed/workspace_tools$ python make.py -t uARM -m LPC1549 -d /media/usb1/ -s /dev/ttyACM1 -n MBED_A1 -v

>>> BUILD PROJECT: BASIC (LPC1549, uARM)
Image: /home/przemek/mbed/build/test/LPC1549/uARM/MBED_A1/basic.bin
{{success}}
{{end}}

I'm preparing Wiki about this, it is still not done, but you can take a look here:
https://mbed.org/users/PrzemekWirkus/notebook/mbed-test-automation-introduction/ (build script)
https://mbed.org/users/PrzemekWirkus/notebook/mbed-sdk-automated-test-suite/ (test script + automation)

Thank you very much for your contribution.

@PrzemekWirkus Thank you, the current master works for me. I will close the pull reqest #363
