I just got the DSO Nano from ADAFruit. Found the upgrade instructions. When pressing the Down and power keys it states
Serial DDCC8AE6 Licence 787B77A0
Device Firmware Upgrade V3.26D
I’m using a Windows 8 pc.
I got a firmware.zip file from the DSO wiki
and it’s contents were:
I copied the first file to the Nano’s virtual drive and in a second or two it said .rdy. Then when I copied the second file the virtual drive closed on my Windows PC and never reopened in over several minutes.
On power up the nano shows white screen with upside down and reversed Seed Studio in Black letters.
That screen flickers.
I tried to do the process again several times but with no luck.
What can I do to get the Nano back to working condition. It was working before tried to upgrade the software.
