2) if  siglent fixes the bug. A license can be generated to keep the 120MHz ability. I have made a license generator.

What do you think to share the license generator?

Hi guys,

Do you think you might be able to help me extract u-boot (including the SPL) from the firmware images, it seems to be present in SDG_transitional.ads.

I've been trying to unpack the ads files myself. I can see the first header (so called 112byte header above) and it's about the right size (130k) for the u-boot spl. However what follows doesn't look like any kind of binary (very low complexity).

Could you tell me how the firmware files are organised? Are there a bunch of headers at the start of the ADS? Or all the different parts of the ads prefixed with a header?

Failing that, if you'd be willing to send me an extracted u-boot for an SDG800 I'd be most grateful.

I'm looking in different firmware files. Many of them have u-boot.
Here is one from SDG800 V100R008B01D01P12R2.ADS
But SDG800_transition.ADS has 3-4 files in it and I don't know
their names. Best bet is this: http://wikisend.com/download/483710/from_transition.zip
File start is promising and from 00 00 4B 30 is starting GZIP
(Header - 1F 8B 00) and You can unpack it to have more of
files. One of them I recognize as logo...

Thank you, so so much for your help! Using the files you posted I was able to recover my Siglent to u-boot. I think it should be relatively easy to get the system booting to Linux now. I wrote up my notes here:
