Hi,


--- Quote from: vishaldotgupta on October 12, 2022, 05:12:33 am ---sucess finally.

i used a stock fw from C series 4 channel and replaced the cal data from my original unit.

The unit now boots up with model TDS2022B, shows 16 measurements as stated in C model and now supports led type display from C model.

Thanks everyone for support

By "stock fw" you mean a flash dump from a working unit, right? And is the "original unit" a TDS2000B series?

I got a TDS2014B with (probably) corrupted FW. At least it shows the typically symptoms, meaning the three green LEDs. I already desoldered the flash and read it out.
My expectations were to see mostly 0xFF, but there is nothing obviously wrong in there. So maybe an update was interrupted just before the finish line?

Is it possible to take the TDS1001C FW from ko4bb.com and put my cal data in there? Or does someone maybe have a readout from a 2000B series unit?   

Fieroluke:
Success again!

Changed my TDS2001C from TDS2022B (ID $0B) to TDS2022C (ID $18)

@Use the Python script to patch the image
How do I use the script, paste on USB and update. I have no idea, I made a copy of U 801 :) |O

TheKellerman:
Install python 2.7. and run

--- Code: ---python patch2.py rom.bin
--- End code ---

This worked for me (I haven't tried the updated pxthon3 script). Then write the flash the same way you read it. You cant put the update on a USB stick.

Edit:
I now see you have a TDS1001B and the patch2.py does not include that in the model check. To which model you want to update your scope?

Fieroluke:
If the scope is a TDS1001B it should be model ID $13 at $7F0007.

Changing it to $12 should result in a TDS1012B, which should be all that’s possible upgradewise.
