Hi. I’ve recently bought DSO nano v.2 oscilloscope and I am quite pleased, but one thing I cannot say I understand - upgrading the firmware.
So this is what I do:
- Press and hold down arrow and turn power on. I get this:
- Attach device to computer (I use FreeBSD 9.0) and do dmesg | tail, dfu-util -l and lsusb:
So if I understand this correctly all I need to do is to extract binary from dfu file and to copy it to this virtual device (which mounts like a flash drive and is empty). Am I right? And how changes can be rolled back in case if something is wrong?
