| olofk | stekern: I'm having some troubles routing a design here with Quartus. Trying to figure out what the hell is going on. Do you know if the Store buffer is supposed to instantiate a 98-wide 256-deep RAM? | 09:33 |
|---|---|---|
| olofk | I'm using mor1kx 2.2 | 09:34 |
| stekern | yes, that might be right | 10:01 |
| stekern | it's 32*3 + 4 + 1 + 1 | 10:02 |
| stekern | -1 | 10:04 |
| stekern | and one less in 2.2 | 10:04 |
| olofk | Looks like there is something fishy with Quartus 14.1. Builds fine with 14.0 | 10:05 |
| olofk | Had other problems with 14.1. It crashes a lot | 10:05 |
| stekern | I haven't tried 14.1 | 10:06 |
| stekern | I noticed that they've dropped cyclone III support in > 13.1 too | 10:07 |
| olofk | And Cyclone II, which is a bit annoying since their DDR2 IP uses Cyclone II primitives internally | 10:13 |
| olofk | So you can't simulate it anymore | 10:13 |
| stekern | heh, really? | 10:14 |
| olofk | All the more reason to finish up the home-made DDR2 controller | 10:23 |
| olofk | Anyone got up-to-date configure flags for openocd? | 10:57 |
| maxpaln | Hi All, does the floating point unit used in fusesoc have it's own repository? | 11:21 |
| maxpaln | I think it should be obvious but I guess I'm not looking in the right place.... | 11:22 |
| imphil | maxpaln, you mean the fpu of mor1kx? it's in the withfpu branch: https://github.com/openrisc/mor1kx/tree/withfpu | 12:06 |
| bandvig | maxpaln: imphil: the FPU is merged into master (https://github.com/openrisc/mor1kx/pull/27). See comment in the pull request how to activate it. I doubt that fusesoc do these steps automatically. | 12:43 |
| maxpaln | thanks - this is good enough, I can find the code now :-) | 14:37 |
| stekern | bandvig: it actually does half the steps, I added the new files to mor1kx .core description | 14:51 |
| stekern | https://github.com/openrisc/orpsoc-cores/commit/c34d964a2aa8c53f66fc7afbe21434e68a996470 | 14:51 |
| bandvig | stekern: Thank for clarification. As far as I understand, to activate FPU the only thing (s)he to do is to add .FEATURE_FPU("ENABLED") in parameter list of mor1kx istance. Am I right? | 14:56 |
| stekern | yup | 14:58 |
| stekern | and I've tested running mor1kx-generic system with that change, and it worked | 14:58 |
| olofk | stekern: Great. Thanks | 15:31 |
| olofk | Will the next release of mor1kx also feature removed Avalon buses? :) | 15:32 |
| olofk | Cool. Running "fusesoc update" works as intended. | 15:33 |
| olofk | maxpaln: I'm halfway through merging in you wb_bfm changes. | 15:34 |
| olofk | s/you/your | 15:34 |
| maxpaln | :-) - Great! | 15:52 |
| stekern | olofk: you never know, but possibly ;) | 16:06 |
