Pushing new code after code is already there crashes tessel

[freethan]

Hi from #fullstackcon,
we encountered the following error while trying to push new code to a tessel board that was already running some older code:

t2 push index.js 
INFO Looking for your Tessel...
INFO Connected to anykey over USB
INFO Writing index.js to Flash on anykey (3.072 kB)...
INFO Deployed.
events.js:141
      throw er; // Unhandled 'error' event
      ^

Error: Error upon remote process exit: 1

Abort trap: 6

After that the board crashes and we lose connection. We had to reboot it and then do a
t2 erase and then a t2 push index.js

Cheers

Thanks for reporting this issue and the workaround! Will need to fix this asap.

Will be fixed with #516.

Cheers! Thanks for getting back to me on this.
I have no board with me at this point and won't be able to test it. Should I close the issue?

[johnnyman727]

I got it! Thanks.
