Re: [WP34s] Flashing with USB adapter successful using Windows 7 Message #27 Posted by Gerry Schultz on 24 Aug 2011, 11:48 p.m., in response to message #26 by Alexander Oestert
I too just had success flashing my WP-34s to version 2.11388. As I mentioned in a previous post, I recently purchased an HP Pavilion laptop PC and I've been curious about if I could flash my WP-34s to the latest firmware on it. This PC is running Windows 7 Professional and I used an ES-U-1001-R100 USB-to-RS232 (FTDI) adapter. After reading Bart's article on "How to get started with a WP-34s", I googled SAM-BA 2.10 and downloaded it from Atmel's website. It's the first download listed. In the description on their website, it stated that SAM-BA 2.10 was for Win7, so I didn't try setting the compatibility mode as recommended in Bart's article.
It installed without a problem and ran fine. I noticed that it takes a long time to start up so I had to be patient. I closed the program and connected up the USB-to-RS232 adapter and Win7 identified it immediately and installed it successfully. I did go into the Device Manager and change the assigned serial port from Com 3 to Com 1 but that's not important. I then followed the 20b reflashing procedure and it worked the first time!
Very Cool. If there are any questions about my setup or what I did, please post.
