If the memory wasn't detected properly It would complain showing unsupported memory error.
The scope rebooting is a completely new behavior that I've never seen before!

Are you using latest version? Or did you copy dsoflash to the 4pda thread? Because it's been updated recently to correct a bug not restoring the firmware properly, also got much faster.
I noticed a unnecessary step in the .bat files, since now dsoflash sets the usb to high-speed mode by itself, sunxi-fel is no longer required.
Updated the files. But this would not cause any rebooting, just set the usb mode twice.

Hi!

I reactivated my 2D15 after a few months of non-use, and noticed that there was no waveform display - which I thought was due to wrong trigger settings.
Then I noticed that only a few keypresses work (Trig Menu, or CH1 Menu, a few others), but then the UI freezes.

As the USB and SSH console still worked, I could reboot without my local modifications -- same problem. Even dropping the CPU overclocking doesn't help.
Remove the USB cable doesn't help.

dmesg or the serial console have no (error) output when pressing the keys; the UI freezes, but the console keeps working, and the phoenix binary looks like it's running normally, using 98% CPU like always.

As (some) keys work once or twice after reboot, I don't think it's hardware-related - can anyone offer ideas what is wrong?

Thanks!
DavidAlfa:
Press load defaults. 98% CPU is normal in this device.

I don't know if this is helpful, but my unit (overclocked) only crashes in the first few minutes after startup, if at all.
It depends a bit on what is turned on from the last session.

Then when I turn it back on, it runs for hours without interruption.
It looks like it might be "too cold" when it first starts up.
Sounds strange, but I can't explain it any other way.
Maybe it has something to do with the new PSU?

It's best not to do anything to it for 2 minutes after starting, at least with my device. Then it runs reliably.

But that probably has nothing to do with your case.
DavidAlfa:
It's probably the RAM, happened to me too. I just leave it stock, OC only the CPU.
You'll get nothing out of that extra 5% OC else that lockups.
