So yesterday both of my old Altera Blaster programmers were found to no longer work. They work on an older machine no problem.
- Device Manager reports code 39 that there is a problem with the driver.
- research suggested this is a driver signing issue so I followed instructions to boot with driver signing disabled still not working.
- I then booted up into Safe mode, installed driver by pointing to the relevant folder in the IntelFPGA directory. This time no yellow triangle. Driver works and is installed.
- Boot back into Windows normally, little yellow triangle is back in device manager and it no longer works.
- Thinking it may be a clash with other drivers on my machine (last chance saloon now), I re-installed windows. Still not working.
This has happened only very recently, like in the last couple of months at the longest as I was using it March/April with no issues.
I am using v18.1 of Quartus because of the stupid NIOS bugs in later version that prevent the NIOS EDS tools working properly. And I have even tried using an older version of the drivers from the installing v16.1 of the standalone programmer.
Can anybody offer a solution please I am desperate right now, I have a hugely important project to work on and nothing I try is working.
I used to trust Altera stuff, it seems the tools are getting flakier and the support is falling away.
I would recommend you to download Quartus 21.1 version of standalone Programmer in order to get the latest driver which will fixed the issue.
