Reading memory results in exception

[svenKautlenbach]

When trying to read memory I get "ERROR: ord() expected string of length 1, but int found".
When removing the mdebug at the read section, I get similar error when it tries to write data to file - "ERROR: sequence item 0: expected string, int found".

Ok, I think I managed to get it correct. Maybe it is the fault of python 2.7?
mdebug(5, " 0x%x: 0x%02x%02x%02x%02x" % (conf['address']+(i*4), rdata[3], rdata[2], rdata[1], rdata[0]), '\r')
file(args[0], 'ab').write(''.join(str(reversed(rdata))))

Interesting bug, thanks for reporting it.

Are you getting back the correct data after making your proposed fix? It sounds to me that cmdMemRead is returning something that it shouldn't into rdata

Hi!

Sorry for slow response.
Actually this fix did not work, it just enabled to run the script with no problems, but inside the memory file was still incorrect data. And I have lost the file now, but there was text something about the iterator or object at 0x######. Can you assert which python version you are specifically running.

[JelmerT]

The script should work with both 2.7 and 3.4.
Are you maybe willing to share the firmware file with me, so I can try to reproduce the error? If you still have it.

[svenKautlenbach]

It is Contiki build, I simply am not allowed to share the specific binaries :(

[JelmerT]

I understand, can you share the command you used to try to read the memory? Could have something to do with the length and location.

[svenKautlenbach]

Sorry all gone by now. I will try to reproduce it when I have time, I will just try out and experiment with the script. Could you please hold on for now?

No problem, I'll close this for now, feel free to comment when you come across the problem again.
