Espruino dead on windows 8 after first write

Hi,

I have been trying to get my espruino working for several weeks on windows without luck.

I have posted about this before but did not get a response.

It worked fine on my first attempt, I sent the demo code to the board from the web ide:

var  l = false;
setInterval(function() {
  l = !l;
  LED1.write(l);
}, 500);

This did not seem to load to the espruino and since then it will not assign my espruino a com address. I can access the espruino on a mac, however I do not have ready access to a mac so this is not a solution.

There is no information on this issue in the troubleshooting, I would try a reflash however without being able to connect to the web ide or putty due to lack of a com address my espruino is essentially useless.

Has anyone had similar issues? surely there is another way to reset the espruino back to factory without having to buy myself a mac.

@Gordon Sorry I just dug up the old post and you did reply (I didnt get the notification). I went through the troubleshooting, uninstalled/reinstalled com drivers, tried on another windows pc, tried putty, removed all com devices from device manager, com device appears when plugged in but no com address and device is unknown. I have exhausted all options provided by your documentation.

Ok I finally managed to get it to work...

Installing the drivers is not enough. you need to then run the windows troubleshooter via the device manager to get the option to manually select drivers (the option is grayed out when accessing device property via devices and printers which is where I got caught before)

Once you can get access to this interface, you can point windows to the folder the drivers were installed in (for me C:\Program Files (x86)\STMicroelectronics\Software\Virtual comport driver\Win8) and the computer will once again see the device.

Hopefully this should stick this time, i've tried removing and replacing the device several times and it seems to be stable.

Not sure why this worked without fuss on first attempt but not on subsequent attempts. I have a suspicion it may be due to firmware versions as my espruino sat in its box for several months before I cracked it out.

I immediately updated the firmware after getting it running today. A more detailed guide for this issue in the troubleshooting section could save others from the frustrations I encountered.

Interesting. Thanks for taking the time to post how you got it working.

For most people, on win8, it just works... I wonder if you have/had some other driver installed (from some other package) that windows decided to use instead...

Re: code tags - the forum uses markdown (like on github). For code you enclose in ``` (on it's own line); Words with *'s on either side get italicized, etc. The forum software is kinda flaky though, and the buttons refuse to do anything more often than not.

Yes, thanks for posting up - Maybe if windows doesn't find drivers when you first plug the device in, it just stops looking in future, even if you then install the correct drivers.

You can probably also fix it by going into Device Manager, going to the properties on the device with the problem and choosing 'Update Driver' - and as you say, then manually pointing it at the right directory.

P.S. Code tags (```) do work, but you need to have an empty line before and after them (I just altered your post). I think it's 'normal' markdown, but some Markdown parsers (like GitHub's) have now started accepting the code tags even if they're not spaced out with a newline.
