| Fallenou | hozer: so is it "working" now ? | 14:11 |
|---|---|---|
| Fallenou | happy new year everyone here :) | 14:11 |
| hozer | Fallenou: sorta ;)_ | 19:31 |
| hozer | kristianpaul: you around? I have plenty of LUTs if I turn off the TMU and keep the SDRAM controller | 19:32 |
| kristianpaul | pop | 19:32 |
| kristianpaul | hi | 19:33 |
| kristianpaul | ah good so bram is way to go | 19:33 |
| kristianpaul | ah | 19:33 |
| kristianpaul | well but porting SDRAM something i'm not very aware of | 19:34 |
| kristianpaul | hozer: what you need the lm32 soc? | 19:35 |
| hozer | well, I kinda want to have something that can output vga like this: http://devbisme.webfactional.com/blogs/devbisme/2011/06/02/simple-vga-interface-xula-fpga-board | 19:37 |
| hozer | and take a video input stream over ethernet, and do some subset of what the 'real' milkymist can do | 19:37 |
| hozer | What I would really like is a board with an LX25T and hook the MGT's (serdes) up to a displayport | 19:40 |
| Fallenou | hozer: if you use another board you will most likely have to change the SDRAM controller | 19:47 |
| Fallenou | make your own | 19:47 |
| Fallenou | or drop it and use SRAM (blockram) instead | 19:47 |
| Fallenou | on-chip sram* | 19:47 |
| Fallenou | or off-chip sram in DIP packages (but slower) | 19:48 |
| hozer | the Xula2 board I have has an sdram chip on it | 19:53 |
| hozer | I've been reading up a lot on displayport, mini-displayport, and DDR3 | 19:53 |
| hozer | and I think the LX25T should be able to drive 2 1080p displays with displayport | 19:54 |
| hozer | and Xilinx is supposed to have a 'mig' DDR3 controller | 19:55 |
| hozer | What I want is a really small board with: Displayport, LX25, phy chip, and 8-bit supervisor micro (with 10mbit) for debug | 19:59 |
| hozer | and sdram, too I suppose. | 19:59 |
| kristianpaul | better use xilinx memory controller yes | 20:38 |
| kristianpaul | anyway is implemented on the fpga it self | 20:38 |
| Fallenou | oh yes that's right you can use on-chip hard wired ddr3 controler | 21:54 |
| Fallenou | I hope the dram chips on the board are compatible with the controler :) | 21:55 |
| hozer | The Xula2 board I have uses a 16 bit SDRAM, so I have some 16 sdram_dq pins hanging around with nowhere to go ;) | 22:21 |
| lekernel | hozer, considered buying a M1? | 22:21 |
| hozer | well, it's expensive and I already have a Xula ;) | 22:22 |
| hozer | err, Xula2 | 22:22 |
| hozer | and this is sort of my brute force method of learning verilog too | 22:23 |
