| openpowerbot | [slack] <Matt Johnston> having built for arty with a pmod connector sdcard (and `use_litesdcard=true` in microwatt.core), I'm not seeing anything, not even interrupt counts when I add/remove a sdcard. are there other things that need enabling for that? | 10:27 |

| openpowerbot | [slack] <Matt Johnston> aah, the `arty_a7.xdc` pinout appears to be for a different pmod board | 10:34 |
| openpowerbot | [slack] <Jeremy Kerr> @Matt Johnston given Joel's comments, is the pinout as expected? | 10:37 |
| openpowerbot | [slack] <Matt Johnston> I think it is, I was just mistaken with spi vs 4 pin modes | 10:38 |
| openpowerbot | [slack] <joel> @Matt Johnston have you fixed up the device tree? When @Anton Blanchard was playing with it recently he had to make updates to match the upstream mmc driver | 10:49 |
| openpowerbot | [slack] <Matt Johnston> ah I'll have a look, thanks | 10:53 |

| openpowerbot | [slack] <joel> @Matt Johnston this is what Anton used. I've not been able to test it myself | 12:28 |
| openpowerbot | [slack] <Matt Johnston> ah, I don't have clocks | 13:07 |
| openpowerbot | [slack] <joel> The driver will fail to probe without that 😞 | 13:07 |
| openpowerbot | [slack] <Matt Johnston> this is 5.16rc1 | 13:07 |
| openpowerbot | [slack] <joel> It's unfortunate, in inherits a bunch of stuff because of the way it sets up clocks | 13:08 |
| openpowerbot | [slack] <Matt Johnston> it _seemed_ to probe | 13:08 |

| openpowerbot | [slack] <joel> I see! None of what I said matters; you're using the out of tree driver | 13:09 |
| openpowerbot | [slack] <Matt Johnston> aha | 13:09 |
| openpowerbot | [slack] <Matt Johnston> ok yeah, merged jan 2022 | 13:10 |
