content: Hi folks:Does anyone know how I can re-load firmware into a siglent SDG810 func gen? It served me well for years and then just hung at the boot screen. Siglent sent me files/instructions for reloading from usb, but that does not work. A note in the instructions indicates that a min level of existing firmware needed to be present and I presume mine is earlier than that.I opened it up, looking for a programming port (I have various jtags pods...) but saw no obvious connector or pad arrangement. There is an sd card socket on the board however, so I am optimistic that code can be loaded via a card, however I get no response from siglent on that possibility.I have a siglent spectrum analyzer which is actually pretty nice, and a 350MHz scope which is ok, but I recently got an SPD3303C power supply which had an out-of-box dead channel (they replaced it), and now this generator fail, so I am kinda burned out on siglent. I have moved to a keysight scope and got a rigol func gen, both of which I love.But I'd hate to toss the old SDG810 and would like to re-flash it and give it to my son. Anybody have any pointers?thx, gil

content: Thank you tautech, for your invaluable help, I made the consultation with Siglent in Germany, they gave me support to some extent, I explain only helped me to perform a system restore through the usb, but this did not work, in my device I have never used the usb connections, which has in endowment, so I do not know if they worked or otherwise as a result of the fall of the operating system has stopped working, I just do not know.As this did not work, I got back in touch with the support and the solution they gave me was to send my generator for verification.Of course, this without certainty that it will work properly again, what surprised me is that at no time did they contemplate providing me with the option to perform a reset through the micro sd memory that is provided.Does anyone know anything about the initialisation of the generator through the micro sd memory?Thanks again

content: Quote from: widi on November 08, 2024, 08:30:55 pmI know plenty about SD card recovery, which for early/old SDG800 that have never had FW updated is reliable although the process is a little complex.EU and US HQ are reluctant to share SD card recovery as it seems they think it is beyond the capability of the average Joe....Send PM with your email, SN# and any info you have on any FW updates you have done.

content: Quote from: tautech on November 08, 2024, 11:34:53 pmThat's probably because Joe Average is the typical customer targeted when offering function generatorsMost electronics guys did not get the concept of "computers" "SD cards" "press button A, then B" yet.Just kidding (a bit), I very much appreciate you help (even though I did not need it, yet).
