Need help with restoring License eeprom Lecroy 7200A Wavepro
mldevw:
Hi,
I am also sorry I did the exact same mistake and bricked my (all new to me) WaveSurfer 343.
I can build a OneWire Interface with arduino no issue. May I have some hints where exactly to look / what to change on the eeprom to get my old licenses back? I have a screenshot of them.
Thanks a lot in advance.
DaJMasta:
Would have been helpful to share some info on how/what you do rather than just posting that it was solved, but let's see if we can get to that point again:
I've got a WavePro 7300 that had no hard drive, I've been able to install an OS, system drivers, the X-Stream software, and the requisite driver packages, but when I boot the X-Stream software, it gives me the "No hardware detected, not authorized to run on this system" message, even though the drivers for the PCI card and all subsequent components have been sorted. I see the same error when I pull the PCI interface card entirely.
Well I assumed that the DS2433 eeprom on the PCI card was bad, so I desoldered it, mounted it on a carrier, and had at it with the arduino sketch and.... well it still has data, though some of it is certainly not alphanumeric (not sure if this is correct formatting). As I haven't seen the output of a working one, I don't know if this data is corrupted or if it's just fine and the fault lies elsewhere, so if there's someone who knows or who has an eeprom to compare it to, mine is included as an image, since some of those early characters evidently can't be pasted in a post (short line is ROM ID, second line is "flash" contents).

Your DS2433 is fine. You're able to read it and it contains your licenses:

The "No Hardware Detected" / "Not authorized to run on this system" error is not related to the contents of your EEPROM, as you observed. This message pops up before the contents are examined and I would say you either have a driver issue or something has gone wrong with your PCI interface card. This error means that the XStream software wasn't able to communicate with the hardware and determine the scope id. Recent versions of XStream/Maui software go looking for a Maui Studio license at this point.. Maui Studio is the productization of the simulation mode that allows you to run the firmware without being connected to hardware. You can't capture any real data but you can analyze data captured on a real scope and simulate measurements. Cool as it is I don't know how useful a feature the simulation aspect is..
Anyway my point is that it's not talking to hardware, hasn't read the scope id, and can't even think about reading the contents of the EEPROM yet. You need to look elsewhere.

Thank you, I've made some progress with it.
I put the DS2433 back on the board and replugged it, the OS only saw a single LeCroy device attached, so I reran the driver installation package, and though the same had been successful before, it seemed to take better this time, and I've gotten past that error. In fact, for practical purposes, the scope works, oddly except for the options.
The scope interface boots up, starts acquiring, can be recalibrated through the service menu, and appears to allow all normal control and operation, except that it has no options listed in the utilities -> options tab, and the ScopeId is ffffff-c4, even though the serial number is now displayed correctly and matches the back of the unit (also IDs as a 7100, but I assume this is just a bandwidth license thing)
Now the weirder part, I update XStream to 8.1.2.0 I had the touchscreen configured and working, but it seems to have stopped working - and the device manager is back to a single device... so I go to reinstall the drivers. Everything reinstalls correctly except for one "Multifuction Device" which I manually point to being a "LeCroy Data Acquisition Device" and it installs without complaint... and even though the port showed up as installing, it seems to be absent on reboot.
I'm going to have to swap PCI slots and see if it makes a difference and then maybe try taking a look at the PCI board itself - it seems to work fine on one hand, and then seems to be up to something on the other.

I don't know what's going on with your acquisition card driver disappearing but as for your scope id, you haven't reinstalled the DS2433 correctly. Make sure it's not backwards and doesn't have any solder bridges.
