I would like to see the entire sniffing data that smaultre posted. It would be helpful if you could attach it.
Because the commands in the updater only use 2 (CF,PF) of the 7 EXTENSION COMMAND that are defined.
know if this is only the case for THS3000.
I tried writing the 190II_V11_46 binary to the THS3024. It works fine.
I also tried writing the calibration data to the 11.46'ed 3024. It is recognized normally. No error also appears.
It is safe to assume that the pcb are exactly the same. However, the keypad layout is different from 190II. It is not usable.
At present, are in a situation where I can analyze the data without worrying.
It is no longer necessary to go to the trouble of soldering a flash to write. Everything can be solved with serial commands.
The waybackmachine is provisionally available.
was available to some extent from the archived fluke site., but could not get the 10.41 updater.
11.10 was available, which is the next oldest after 10.41.
The updater I was able to obtain is attached.
Difference between data in qc and wc:
23 30 80 03 E3
is added at the beginning.
03 E3
is the chunk size.
Then, for each chunk,
?? ?? 0D 30 0D 23 30 80 03 E3
continues to the end. The last chunk has a different size.
I believe that the two bytes indicated by "?" are calculated with some kind of checksum. It is different for each chunk.
The updater adds 0D for each completed transmit(each chunk).
This is the same behavior as when writing to flash with the EXTENSION command.
30 0D
is not relevant. I believe it is a ACKN response from the scope.
The way I dumped it, I put TX and RX in an AND gate and receive with a separate USB serial adapter. So all data sent and received is sniffed.
Also, the firmware of the internal PIC microcontroller was found to be included in the flash dumps and LDFs.
there seems to have been an update to that in V11.20.
The comma-separated first part of the subversions shown in the scope's VER&CAL is the firmware version of the PIC microcontroller; the second is the firmware version of the FTDI VNC1L.
Just to be safe, I dumped the firmware of the PIC microcontroller with TL866 before applying 11.46 to THS. attaching it in case it fails, but can probably extract it from the updater LDF file.
