Again, thanks for all the info. Didn’t realize the world of USB Blasters was so dense. Might be helpful to build my own just so I know all the things that can go wrong and better debug in the future.

That’s a lot of quirks with the USB Blasters. I never knew. I should have mentioned that I used Linux in my first post. I didn’t think it was an issue since it was recognized by my system, and I got the udev rules installed, and it definitely communicated at least to some degree. However, timings are always a tricky thing. I really…Read more

Still the same issue. I had a feeling that either the FPGA was shot, or it was a communication issue over the USB port. I switched over to Windows (I used Linux as my primary OS, which is where I did the initial testing).

Windows actually worked to flash the FPGA. I now have a working OSSC again! So, I…Read more

I may just do an order and put some of the other cheap ICs used within so I can test. I guess we’ll see again in a week if this fixes it. =]

I had done the 1.8 mod to the device. Checked everything and nothing with bridged or bad with that. It was running for a while on the v1 firmware just fine. I reverted the mod, and still no go.

I tried loading up the ossc project in quartus and compiling it, but I get errors about memory not being able to be mapped or something. So I wasn’t able to generate an .sof file to test if having…Read more

Seems like your theory about the flash memory being fried might be correct (or at least something along the path to the chip, not sure how the electronics are routed).

Here’s the log:

Gotta at least try! Got the $12 one, so I guess I’ll try it when it gets here in a week or so.

I don’t have a USB JTAG programmer sadly. Sounds like it might just be fully bricked, though. =

Have been waiting for the ossc pro to become available again. Might just buy that rather than spending extra money trying to figure out what happened.

I tested D4 again and now it seems to be showing the correct voltage in a single direction against pin 2 for all other pins. So I’m at a loss as to what it could be. Is there a known suspect for when there’s no output, no LCD output, but all the lights and everything are working? I tested…Read more

It sparked, and then the LCD screen went blank. There’s no output over HDMI now. Everything was working fine before this.

I have OSSC v1.7 hardware.

The backlight still turns on, the D1 led is faintly on.

I tested F1 and the fuse seems to have continuity running through it.
I…Read more
