Does anyone know if there is a freeware virtual com port driver to use with Atmel's Samba to install the TinyBooterDecompressor? I've used two freeware programs which work great but are limited in time and a license key is pretty expensive. Any hints? Also on one occasion Samba found a USB com port (on board the Netduino?) which worked too. But I cannot reproduce this. Can someone tell me what's up with this? Thanks in advance! For some reason my netduino+ seems to be totally frozen quite often, even MFDeploy can't connect to it which only leaves me the 'hard reset' option. Since I'm a beginner, it might be an operator error of course. Using µFW 4.2 for VB in VS2010.

SAM-BA is the normal tool for this, and is free. I didn't even knew there were non-free tools for that purpose? The driver comes with SAM-BA.

The 4.2 firmware for Netduino and Netduino plus is still beta and I know of this issue. I hope the next RC (or RTM) will have this fixed, but I can 'comfort' you by telling you're not the only one experiencing that issue :)

Strange - I had Samba 2.11 and just installed 2.12 but Samba doesn't find its own COM-port then (other than the odd occasion earlier today). I had to install (and will have to again) another software and select these COM ports in Samba. There are no COM ports listed in my PC's hardware tree.

OK, fingers crossed then. The full reset is not a real problem once you know the procedure. It's just that after the evaluation period expires, I need to find another virtual COM port package. I wonder what's wrong with Samba then and why it did work but only once this morning...

Strange... Drivers are placed at "C:\Program Files (x86)\ATMEL Corporation\sam-ba_2.11\drv" here...
