DSO5102P bricked on main screen

lggomez

Hi

Mi DSO5102P is stuck on the main screen after initializing with the message "Error: Fpga version does not math with the app!!"



I can not update firmware nor restore anything because there is no way out of this state. Since the power-up, the oscilloscope does not respond to any input

Appreciate any solutions

Having the same issue with the same scope. Seems to be a chronic issue with these. For some reason t ...

Thanks, I thought I was the only one having this issue since I could not find any relevant content on the web. The frustraing part is that the unresponsive controls don't allow me to restore the firmware

PCB is different but I could see the same componentes, altough I could not get any clear voltage readings unfortunately (mV instead of V)
The 1kHz probe calibrator line on the other hand gives me a very wide range between 50 and 30kHz. Voltage is the same, can't get a significant reading (it gives me mV values)





Since all controls are on I don't trust my multimeter very much, but I could verify the frequency oscillations on the calibration line by comparing with a signal generator

Is the 4GB SD card a hard limitation? I tried to flash with a 32GB card with a 4GB FAT partition but without success. Will try to get a card of that size

As for the tools, I really can't verify the process was successful when I prepare the card and I get the following error when trying to flash

I'm trying with a 2GB sdcard and it doesn't get recognized by the device, it's a black screen. The software does nothing at all and I don't have a way to know if anything happens or not



This is unusuable, I already had to get the trouble of creating an XP virtual machine and the 2GB sd card for nothing, please provide another bootloader version or way to format the sd card if available

Dear Sir，
This programming operation must use a 4G SD card.

Ok, will have to get a card of that exact size then and try again, right?

I finally got a 4GB card. The tools still don't look like doing anything to the copied files and I get the following error



I need advice to know if this is still recoverable and if so then some new way to make the sd card bootable (it that's the issue)

Please can I get support on this. It is unacceptable that an unit with less than 10 uses after months in its box suddenly breaks like this and the only option I get is a software without translation on an OS deprecated 8 years ago

Dear Sir，
Yes, you must use a 4G-sized SD card.

Please see my last response w/picture. This is already using a 4G SD card

I never expected support to be this bad... I will tell anyone to avoid this brand like the plague whenever I have the chance, this is atrocious
