Rigol DHO800/900 Oscilloscope Bug Reports + Firmware

[Fungus]

RIGOL just released a software update, hopefully it fixes some stuff like the LA channels not decoding SPI

The release notes say it's fixed, it's item 10 on the list.

See my thread here: https://www.eevblog.com/forum/testgear/rigol-dho800900-new-firmware-1-03/

Hm,
it seems that Rigol has withdrawn their newest firmware release: DHO800_DHO900(Software)Update_v00.01.03.00.06.zip. It vanished from their websites.

Has anybody info about this? Can or should I do back to v00.01.02 ?

many thanks

Heads up, guys, I think I found a really bad bug in the new firmware.

I think it's related to the XY mode crash bug which was reported earlier.

Setting defaults lets you open XY window, no problem, but I think I powered down the 'scope yesterday when it was in XY mode and today it won't boot up any more. The 'scope app crashes on startup.

ADB is running OK, even  Webcontrol is running OK, but the scope app won't start.

I found this in the log file which seems to confirm the XY window is the problem:

I've tried downgrading the firmware via command line. It does the same thing.

I even tried an older firmware image (Dave's original image as posted in the hacking thread!) and it still won't start.

How do I get it to revert to default settings on boot (ie. with no XY window open)?

I did "hold down the DEFAULT button" on power-up thing but that doesn't work. There has to be a way, surely, but Google is failing me here.

Bottom line: Do NOT power off your DHO in XY mode until we figure this out!

Setting defaults lets you open XY window, no problem, but I think I powered down the 'scope yesterday when it was in XY mode and today it won't boot up any more. The 'scope app crashes on startup.

My scope had the same failure to boot, but after using the feature to load the previously used setup on booting.  I unplugged all of the cables overnight, and it booted the next day.  And, yes- I do regret buying this scope.  And, no- RIGOL doesn't seem to care.

Rigol went from cheap and good enough to cheap and not-good enough.

I have a weird problem... I just updated the firmware on my DHO924S to the latest version on Rigol's website (00.01.02.00.02) and now the screen is mirrored:





What the heck caused this?  Is it a setting I can change? 

The touch digitizer still works in the normal orientation (it's not inverted).  If I plug it into an HDMI monitor, the monitor shows the output in the correct orientation. 

[bobasaurus]

Hmmm... it mirrored itself back to the normal orientation again after waiting for a while without touching it.  Very odd. 

Edit: I restarted it and the screen is mirrored once more

I was just watching "Dracula" (1931) where Bela Lugosi says "I dislike mirrors;  Dr van Helsing will explain."

[bobasaurus]

I downloaded the same firmware files again, removed everything from the flash drive, copied these fresh files to the flash drive, verified with WinMerge that they weren't corrupted, then updated the firmware on the scope again.  Now it's the correct orientation and has stayed that way through a couple restarts.  So maybe file corruption, or some weird setting (like RTL layout?) that carried over from the old stock firmware that's now overwritten. 

Edit: Darn, it mirrored itself again after running for a while.  Very odd, maybe a hardware issue with the display?

My guess it's a corrupted device tree or Android settings. I have copy of dtb, so it will be in the attachment.
