Re: mame-on-a-stick

Thats amazing!! Anyway you could post a video and link it?  It would be cool to see it in action and maybe even a little information on the hardware and software.

Analog Reference Circuit

Hello All, I had a quick question about the analog reference voltage circuit in the XS1-U8A data sheet. I noticed that they give three example circuits 1. With and XTAL, 2. With an Oscillator and 3. The bare minimum. I noticed that the third one is using a PI-Filter to remove high frequency noise fr...

Re: XLink (-L) Non-volatile Memory and I/O Service Board

Hey I noticed that the XLINK VHDL implementation is well advanced. Where exactly did you find documentation on the XLINK protocol? Or did you scope it and reverse engineer it? Think I could get a peek at your VHDL code?

Troubleshooting XLink Code between custom boards

Hello All, I'll be honest, even after going through the "Tools User Guide" the creation/tweaking of XN files escapes me. I'm trying to do something pretty basic, continuously send a packet back and forth between to XS-L1 Custom boards. The program compiles but when I scope pins 52-55 on th...

Re: Flashing XS1-L2

I'm not sure if this is the same problem but I was having similar trouble. I would test the code using the "Run As Application" method and then it wouldn't let me write it to the flash. After messing around with it for awhile this worked: -Assuming the flash chip is correctly connected 1. ...

Re: XCore 2 is not enabled error in 4 processor pipeline

hey rp181, Doubt this will help but I got the same thing where it would recognize the cores attached to the programmer but it wouldn't load images. My problem was that one of the capacitors for the clock wasn't soldered all the way down so although the oscillator was starting up, the signal wasn't r...

Re: communicating with the XC-1A via USB

I'm confused, are you trying to send data from your Dev Board to the computer via the UART? or are you trying to interface the board via a custom USB driver?
