Help restore SDS1102CML+ after unsuccessful flashing
smittyinthesky:
I would like to add a "me too" posting in this thread. I think I have a similar but different issue?
I recall I attempted to flash the firmware on my SDS1102CML+ and it never came back up.
Here is my serial out put.

I've done the USB recovery with P21R2.7z but I still get an error about /dev/ttyO0 not being found.
Does this look like a bad board or a bad kernel/firmware?
Thanks.

Is the scope working or not?

tautech got me up and running with proper recovery files. just working out the last few items, but it's back up and running.

Yup.
Note to all, please don't go opening your scopes to sniff any data bus .....it's just not required !

Hi. :)
I’m also new to the forum, however long time viewer of Dave’s YouTube channels. I’m only a bit of a hobbyist & recently when I tried to use my Jaycar QC1934 oscilloscope I have also fallen victim to the “Stuck on Splash Screen” issue that has been discussed in this forum. I have never updated the firmware and seemed to work fine for the last 3 or 4 years.
I believe it is actually the siglent sds1102 cml plus, correct me if I’m wrong Ref attached photos. No relays click just splash screen, Repeatedly pressing math button doesn’t do anything. Just all buttons lit up and a led inside pulsing. It has a sd card slot, lan port, usb, bnc connector & an unpopulated J11 pads.
I have tried to contacting siglent for support, the American address info@siglent.com keeps bouncing back, no reply from the other 2 email addresses.
Any help would be greatly appreciated. TIA
