This script should work on a HDB2002B with firmware >= 1.00.2 where system.inf is located in /dso/root. It won't work with firmware 1.00.1 where system.inf is in /etc.

Indeed I am FW 1.00.1. Which means of course that the other firmware update scripts will also not work.

I would be most grateful for a set of files that allowed me to move up to something better than my current level! If you could mod your files and provide a link that would be superb. :-+

Some news on the PSU/isolation thing:

I did try installing the digital isolators. ADUM2400 fits pinout-wise and data-direction-wise too (tested for U14 only at the moment).
However, i got sent the wrong parts (-ARW suffix) from an incompetent seller, which are only rated for 1Mbd and have much too high delay, so it doesnt work. Some signal gets trough, but it doesnt look good.
Now ordering the correct (90Mbd) -CRW again, but this time at a distributor that hopefully knows what they are doing...

Not sure what you all will make of this. I have been in touch with Hantek because of a dodgy PSU in my HDG2002B. They are going to ship me a new one. But I also mentioned that a firmware update would be nice.

They provided me this file... https://dl.dropboxusercontent.com/u/46144181/afg_hdg2000b_150807.upk  :-+
    ...which then bricked my machine. Sigh.  |O

Maybe someone in the forum can make something of it. It is dated very recently...

So now seeing if Hantek can sort this out. (Yes I know I can get in there with a UART as I have before, but for now I want to see how the "official" solution works out before I have to go up a learning curve I'd rather avoid)

cheers

Well, Hantek actually responded with a set of files that seem to provide a telnet link via the USB port. https://dl.dropboxusercontent.com/u/46144181/Hantek%20USB%20cmd.zip This certainly got my device working again. I suspect this might be a more generally useful tool if you want to shortcut the UART access effort. I leave it to those with the skills and interest in the forum to investigate...

cheers

I got my new HDG2002B with the following

PCB 1004.1
SW 1.00.3.03.05 (150710.0)
FPGA 41

Can still be hacked to HDG2102C.

fremen67, I found a bug in your spreadsheet when attempting to do the calibration with my Rigol DS2000 scope. In the function "GetVoltFromDS2000A" you have "GetTimeScale " when it should be "GetDS2000ATimeScale". Once I changed that (and spoofed the DS2000 into DS2000A) it then worked.

great work everyone on enabling this easy upgrade.
