firmware upate failing updating to v1.8.2?

Hi, I just tried updating from v1.7.0 to v1.8.2. The app updates without issue but I cannot find a way to successfully update the programmer firmware. The Zadig installer does not detect the programmer; if I look explicitly for all devices then it is in the list, but the install process aborts after...

Re: 93c46 programming: verification fails, but contents are correct on 2nd reading?

Hi ArT, Briefly reviving an old thread but with (I think) a resolution. As I described, I'm using RevelPROG in Windows 10 under VMWare on a Mac laptop. I found that if I disabled VMWare's virtual support of USB3.0, and set it to USB2.0 instead, things improved very significantly and I got programmer...

Re: 93c46 programming: verification fails, but contents are correct on 2nd reading?

Hi ArT, The write verification error gets reported after a long (4-5s) delay watching the progress bar; once the error is reported the buffer displays all zeroes. If I try to read the device again, the buffer displays the correct contents. So it seems that reading and writing both work, just slowly ...

Re: 93c46 programming: verification fails, but contents are correct on 2nd reading?

I'm allowing 2 cores and 9GB memory for the virtual machine. Given the light use I'll make of the programmer I'm not overly concerned by waiting a few seconds; my bigger concern was the initial verification failure. I'll see if increasing core allocation makes a difference.

Re: 93c46 programming: verification fails, but contents are correct on 2nd reading?

Hi ArT, I just tested the programmer on a friend’s PC (using the zadig drivers, same as on my vmware system). It works fine, and is at least ten times quicker; read/write processes take around 0.4s rather than 4s. So I guess the odd behaviour I’m seeing is related to the virtualisation. Is there a p...

93c46 programming: verification fails, but contents are correct on 2nd reading?

Hi, I just purchased a REVELPROG-IS programmer in order to make duplicates of a 93c46a serial eeprom in an old (25 years) synthesiser I am restoring. I did some tests on some new 93c46a devices I bought to act as the original's replacement, and found some odd behaviour. With a new 93c46a device (a M...
