| openpowerbot | [mattermost] <lkcl> paulus: i got 30 mhz execution out of nextpnr-xilinx on the older version of microwatt.v | 17:04 |
|---|---|---|
| openpowerbot | [mattermost] <lkcl> which given that i'm using HyperRAM PMODs not DDR3 is perfectly fine | 17:04 |
| openpowerbot | [mattermost] <lkcl> got up to initialising the mmu | 17:05 |
| openpowerbot | [mattermost] <lkcl> [ 0.000000][ T0] radix-mmu: Mapped 0x0000000000600000-0x0000000004000000 s | 17:05 |
| openpowerbot | [mattermost] <lkcl> <- early_setup() | 17:05 |
| openpowerbot | [mattermost] <lkcl> but could probably get further: the clock freq in dtb is still 50 mhz i hadn't adjusted it, for that test | 17:05 |
| openpowerbot | [mattermost] <lkcl> around 50% utilisation of the Arty A7-100t | 17:06 |
| openpowerbot | [mattermost] <lkcl> -nocarrylut which is a speed penalty of around 30% apparently | 17:06 |
