Rigol DP832 - Firmware list and bugs

<< < (149/153) > >>

Mecanix:
That's great, thanks. I'll sure have a look and see if I can at least understand what went really wrong at the first place; unlikely I'll have a go at further modification until I've understood first. The unit appears to be destined to go back to factory for repair/re-calibration, from the look of things (-151.1mV... yikes lol).

Quick question, if you know;  when I get back into Utility > ManualCal > CallItems: only a handful of them registered (7?) although I was referred to a 35 points table. What went wrong? Tried Board's ADC calibration from the gui and that also fails. What exactly blew up? anyone knows?

EDIT: quick shout out to the folks who've contributed in the thread TurboTom shared (and who've contributed too), that fixed the wicked offset on the CH2. All what's needed now is to attack CH1 with a tighter custom points/set and all good to go, I think, dunno lol

Certainly better than -151.1mV where stuff would have seriously blown-up if left on the PSU, even when the channel are switched to OFF. Scary stuff. Do NOT attempt this 'diy cal' if you can't program/script logic yourself, and/or don't have one (or two) days to waste (I'm almost 7hrs in this and only half done lol). Recommend sending off your unit to the factory and be done with it.

I've just got around to try to "upgrade" firmware on my Rigol DP832 to newest version and it looks like my firmware is bugged out. I can't do it. It starts and then it just rolls between 19.2 and 19.1, whatever that means.
When I reset the power supply it powers up and works fine.
I have:
It was calibrated on 04/18/2013
Digital Version 00.01.03
None of the options are present. But everything works. I've connected it to LAN and it's communicating, responds to inquiries I should say, because when I've tried to send the command to switch it to A model it doesn't accept it.
That's actually how I came around to try to do the the firmware upgrade, thinking that it may solve the problem.

bson:
Try a freshly formatted USB stick with only the update on it.  Maybe a different one.

Otherwise it sounds like a hardware problem.  Either the internal supply for the logic, or the flash itself.

Ordinaryman1971:
I've tried two different ones, and two different updates.... let me make a third attempt.

@Ordinaryman1971

"Digital Version 00.01.03" is a very old firmware and some time after v01.03 Rigol also updated the Bootloader-Firmware - I think even twice (once in v1.09 and once more in v1.10) - which must be done separately (same instructions, just a different file that must be installed first). Did you try this?

The current 01.16 firmware archive file, that I have here, doesn't seem to come with the updated bootloader anymore. Previous versions of the firmware archive file downloaded from Rigol always included the updated bootloader image, as well.

Maybe you have to get an older firmware archive file, first, and use this to update to a newer bootloader version for the v01.16 update to work?
