Help restore SDS1102CML+ after unsuccessful flashing
eeKnud:
Big thanks to ratmole for putting me on the right track to get past the splash screen on an SDS1052DL+.
For those interested, I did these steps:
1. Opened the case to get at the main board.
2. Connected a serial console to J11 and confirmed that the unit was trying to boot. (I had right-angle 0.1" headers, so just soldered one on and used jumper wires to connect to an Arduino running serial passthrough)
3. Compared ratmole's SDS1000_arm.app to the one in /usr/bin/siglent/ and seeing they were different, thought what the heck, try it. Put it on a USB stick, mounted, copied to /usr/bin/siglent/ and chmod +'d it.
4. Reboot (from the command line via serial or via the power switch, both work) and removed the USB stick during.
5. Scope now got past the splash screen, but the display was funky; the signal traces were in an odd state/configuration.
6. Put the latest ADS from SDS1000DL+_V6.02.01.13_EN on the USB stick
7. Put the scope into firmware update mode, inserted USB stick, and selected the ADS file.
8. Watched update on the scope and via the serial console. Lots of output, but completed successfully.
9. Enjoyed a happy scope
Todo : give scope to my son for his shop.

1. Remove the back cover of the SDS1102CML+ oscilloscope,
2, Remove the metal back of the cage
3. Connect RX,TX serial cables on the unpopulated J11 connector. Solder TX to the second pad and RX to the third pad.
4. Connect to serial: Baudrate 115200
5. Boot the oscilloscope, now you will see the boot log. If not, swap the RX,TX cables to your serial adaptor.
6. Unzip the contents of the P21R2.zip in a fat32 formated usb stick. Also unzip the SDS1000_arm.zip and copy the SDS1000_arm.app to the root of the usb flash drive.
7. Connect the usb flash drive to the oscilloscope and power off and the on the oscilloscope.
8. Let the oscilloscope to perform the FW Recovery.
9. Remove the usb flash drive and Reboot
10. done!
If the oscilloscope still hangs on the boot logo
Start the oscilloscope without the usb flash drive.
When the boot is complete, but still on logo
Insert the usb flash drive and type in the serial console:
--- Code: ---mount /dev/sda1 /mnt
mount / -o remount,rw
cp /mnt/SDS1000_arm.app /usr/bin/siglent/SDS1000_arm.app
chmod +x /usr/bin/siglent/SDS1000_arm.app
mkdir -p /usr/bin/siglent/firmdata0/usr/log
cd /usr/bin/siglent/
./SDS1000_arm.app
--- End code ---
Now the oscilloscope is back to life!
Please perform a hardware reset using the Math button method and you are good as new.
a big thanks to tv84 and tautech for their help!

Hello - New to this forum. I have a Siglent 1102CML+ that is stuck on the splash screen. I tried inserting USB stick with downloaded firmware from Siglent in the front of the unit per Siglent's instruction. But, this unit is still only showing the splash screen and hanging. Any help is greatly appreciated as this unit has only been using about an hour over it's lifetime and I would like to get it running again. There was no reason for it to stop working (not dropped or damaged in any way). So any help is very much appreciated to help get it up and running again. Thank you. By the way, I did not see a prompt on this forum to add a new topic so I am posting here because it seems the closest to my issue (same Siglent model with a stuck boot process).

Hi guys. I want to update the firmware of my Siglent SDS1102CML oscilloscope. But I'm afraid to get a brick. Does anyone have any sensible instructions on how to flash it? From a USB stick or from a Windows 10 laptop?
