Re: Need pinouts of FPGA chip grid contacts on underside of DE10-Nano PCB

After I removed a heatsink from the Cyclone V SOC I saw there is numbers and letters that I assume correspond to FPGA Pin numbers.

Need pinouts of FPGA chip grid contacts on underside of DE10-Nano PCB

A couple of years ago the USB OTG on my DE10-Nano board stopped working. The DE10-Nano board uses a 'USB3300' IC for USB OTG functionality. Today I discovered I can buy a USB host board - USB3300 OTG PHY from ebay https://www.ebay.co.uk/itm/143453046821 19uSmMZ.jpg My plan is to remove the existing USB3300 IC on my DE10-Nano and then solder wires f...

Re: I am selling used IO Board and 32mb SDRAM module on ebay

Sorry I would not ship to the USA because what I am selling is cheap and so it would not make sense to spend a lot of money, relative to the price of what is being sold, on postage. And I imagine the Coronavirus pandemic is making world wide shipping problematic.

I am selling used IO Board and 32mb SDRAM module on ebay

If you live in the UK you could bag yourself a cheap Mister IO Board and\or a 32MB SDRAM module on ebay that I am selling 2nd hand. Both work fully without fault.

Re: I accidently destroyed a surface mount component from my DE10-Nano pcb

I have a Mister IO board that has the USB serial port. So I could connect a original console joypad if I got a SNAC board interface. But I still would need a way to connect a keyboard. As I understand it a SNAC board can only support 1 original console joypad device. There is the blisster board that has its own USB controller and connects through t...

Re: I accidently destroyed a surface mount component from my DE10-Nano pcb

I found a way to get USBIP working to an extent. Basically I could share a USB keyboard from another computer running Debian Linux and have my DE10-Nano act as a USBIP client and use the shared usb keyboard. I can navigate around the Mister core menu but when I try to launch any core Mister freezes and so does the serial usb console that I have ope...

Re: I accidently destroyed a surface mount component from my DE10-Nano pcb

I dont think the USB micro connector is faulty because I tested for 5V at the connector solder points near 'HPS USB OTG' text on the board. And there was no 5V present. There is 5V elsewhere on the board including on the GPIO connectors.

And I have tried using a powered USB hub to try and get keyboard and joypad working but that did not work.

Re: I accidently destroyed a surface mount component from my DE10-Nano pcb

I desoldered the remains of the destroyed capacitor using a USB microscope. So I think I could be ok soldering in a replacement. One the replies mentioned it might be a capacitor in parallel to reduce noise. I had a similar thought and wondered is this really the cause of why the USB otg port is no longer working. I had a look for other missing com...

I accidently destroyed a surface mount component from my DE10-Nano pcb

Because I was clumsy in fitting my DE10-Nano into a case I 3D printed I destroyed a surface mount device from the underside of the circuit board. After I did that the USB OTG port stopped working. So the board could boot into MiSTer but no keyboard or joypad would work with it. I do some hobby electronics but I have no hands on experience with SMD ...
