Hi, alexitaly
Since we have a consistent hardware platform, if you are convenient, can you share with me your full dump flash file.
I have built a JTAG chain to easily flash any firmware. I think the ultimate solution to all problems is to find the appropriate dump flash files
Hi routerfan.
I'm convenient, but the problem is that i haven't a JTAG programmer (you have a very well Segger). I have only a ST-LINK V2, but i don't know if it can be useful.
I'm thinking to buy a JTAG programmer, but what?
Have you tried the firmware that tv84 has linked? I've tried, and my oscilloscope is as new, with pros and cons.
The bad news is that the keyboard response is not very good, the SCPI commands are not implemented, the USB-memory over 1GB (the old 4GB gold usb key that you can see in some my photo) are not correctly recognised. All these problems are original characteristics of the dso.
If the tv84's last fw doesn't works properly, i think that you could have hw problems: in fact you have soldered and removed a memory chip, but are you sure that the memory chip that you have installed was compatible with our hw revision?
If, after covid epidemic, i won't have any work problems, i'm thinking to change dso with a SDS1202X-E if it hasn't particular problems.
