Last weeks, we are having issues updating MC41 modules via USB-CAN (and some of our service guys told having the same issues with a MC42, but that is unconfirmed). It seems the "Updating Firmware" step takes forever. Eventually we succeeded with one laptop, but it took ~20 minutes, where it would normally take 1 or 2 minutes at most.
Other attempts would result in a "No reply from master module" failure. And what seems to be strange: we tried to upload with IQAN 5.03 but the failure message said it failed uploading Firmware version 6.00.48. So we tried again with IQAN 6.00.48, and the upload was done within a flash... But strange enough, I couldn't upload the same (IQAN Design 6.00.48) program earlier on another MC41. It would also get stuck at the Update Firmware part, and then the older 5.03 version would upload the program without problems...
So we have this issue with both IQAN Design 5.03 and 6.00.48. Tried several laptops, but that didn't make a difference either. Using the same KVaser LEAF Light cable as always.
The strange thing is, we have been using IQAN Design 5.03 and 6.00.48 for quite a long time, without having issues. It recently started. To me, it sounds as if something changed on the hardware, or maybe some Windows (10) update is causing trouble.
