Calibration data cannot be saved #49

Open flbauer opened 4 years ago

flbauer commented 4 years ago

On my DSO203 I recognized that after recalibration after power cycling all calibration data have been lost. I now need to "Reset calib data" every time I want to work with the scope.

When I connect via USB to my Laptop it says that the file system is corrupt. I also cannot get the firmware partition connected to the laptop. So I assume there is a problem with the file system. Any thoughts how to fix this?

After reflashing the FPGA configuration, reinstalling the original software and then installed a version of the software saving of calibration data worked. My assumption is that the Flash-Partition got corrupt and reflashing the firmware reinitialized it.

HW 2.7B, DFU 3.1 Installing:

  1. FPGA 2.61 *
  2. SYS B1.52
  3. APP B2.50
  4. GAB_O2.HEX
  5. LOGO_000.BIN *

(* first copied .ADR File into DFU-partition then FPGA resp. LOGO file)

(This was a lengthy operation since I had to revitalize a Windows 7 computer since the DFU 3.1 does not work with Windows 10)
