02:37 <sajattack> anyone around?

03:26 <sajattack> I guess most of you are german time zone?

05:36 <Claude> sajattack: morning . I took the versa_ecp5 target and adjusted that to my board

05:37 <sajattack> hmm I guess it's a bit different for me since none of the existing altera boards have ddram afaik

05:40 <Claude> Which board do you target ?

05:40 <sajattack> de10 nano

05:41 <Claude> Hmm the DDR is connected to the arm side/hps on that . Right

05:41 <sajattack> it's both afaik

05:41 <sajattack> not really sure

05:42 <sajattack> I know usb and ethernet is directly connected to the hps and only the hps

05:42 <sajattack> but I thought ddram was shared

05:42 <Claude> Iirc there is an article on the altera wiki how to map the hps to the FPGA side

05:43 <Claude> But hps is , as far as I know, a hard macro ddr3 control

05:43 <Claude> Controller

05:43 <sajattack> let me check something

05:45 <sajattack> yeah it looks like you might be right

05:46 <sajattack> any idea how I get memory for linux-on-litex-vexriscv then?

05:48 <sajattack> I'm a bit confused why the de10 manual would list the pins for the ddr3 if it's only connected to hps

05:50 <Claude> I think you need an axi wrapper , accessing the hps bridge from the FPGA side

05:51 <Claude> But not really sure, never did anything with the SoC cyclone 5 . Only with the regular variant

05:51 <sajattack> sounds over my head

05:52 <Claude> You might can get some inspiration from the "mister" project , afaik they use on the Amiga core the ddr3 as memory

05:53 <sajattack> yeah they use it for genesis too

05:53 <sajattack> I was checking if they had it assigned to pins like I do

05:53 <sajattack> and they don't

06:58 <sajattack> I got distracted

09:01 <Claude> Yes at least for the Amiga core they access the ddr3 trough hps/axi . They added a sdram chip on a expansion board for the actual Amiga implementation because it latency of the DDR is too high

09:01 <sajattack> yes

09:03 <sajattack> I have a mister sdram board but I don't want to put it in my pr because it's not part of the board

09:11 <sajattack> but I'm not sure I can shoehorn hps ddr3 in either

12:37 <gruetzkopf> Claude: where are you getting pcmcia card cases these days? ( also: a600, right ?)

12:40 <Claude> gruetzkopf: a friend got me some from China

12:40 <Claude> Still need to figure out how to get more of them :)

12:53 <gruetzkopf> i have a local source for slots that has like 750 pcb mount connectors and 10k card slots in stock for 0.14€/pair

12:53 <gruetzkopf> widest tape of parts i've seen so far

12:54 <gruetzkopf> but nothing for card cases

12:58 <Claude> pollin :)

12:58 <gruetzkopf> ;)

13:02 <gruetzkopf> but both that and the female connector are easily found on alibaba, the metal case isn't :(

13:04 <Claude> yes my buddy in china had to hunt for it as well

16:03 <Claude> hmmmmm

16:03 <Claude> is there a way to set unused IOs on a ECP5 into e.g. input mode ?

16:04 <daveshah> They default to input with a pull down. There is no setting to change this in Trellis atm

16:05 <Claude> ok thats perfect then for me, was just not sure what value/direction they have

16:09 <daveshah> This should also be the case even if no bitstream is loaded
