I have been really busy finishing off some contract work, so I have not had much time to complete the Replay bringup.
I am ordering some more PCBs so I did a quick layout of a daughter board for the LCD. It has an analog joystick and some buttons. Really, it's just to play with the LCD, although I might...
I've finished the layout of the large patch card needed for testing with a real 68030 processor. The board is also used to test the IO on the main Replay card. The three daughter boards will go to manufacture tomorrow.
Four main boards are now in existence and have gone/going to developers. I've been busy getting all the components together for...
Sorry, living in Sweden I couldn't resist this. This is what a Replay parts kit looks like. This board is going off to another developer. Just to repeat, the production board will be available fully assembled only, you don't want to try and build this thing unless you have an SMD assembly machine handy, trust me.
I've been hitting the layout...
I've just been finishing off the layout of the 68K daughter board and the video IO board (pictured below) for the Replay card. The IO board contains audio RCA connectors, front mounted joystick and SVHS / composite video outputs.
These are needed to finish testing the main board before I can build some more. Testing of the main card is going...
It's been a bit of a busy week, I was away for Easter and I am busy installing a kitchen, so I haven't had as much time as I would like to carry on with the board bring up. However, I've got a rough cut of the boot software optimised for the ARM. It's booting ok, flashing lights and talking...
The first Replay board is fully assembled. I am about to power it up.......
Well, so far so good with the testing of the Replay board. The power supplies are all working well with good phase margin. I can configure the FPGA through the JTAG interface and flash the LEDs, so the clock generator is also working. I can find the ARM with the USB connection and configure it. The next step is to...
Here is a picture of the Replay board mid assembly. The BGA has been mounted as well as all the small capacitors and most of the ICs. I have all the parts now, so I hope to have the board fully built for the weekend...
