From 06266fe84a567b285cb280611756a59bb6b88810 Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Fri, 24 Sep 2021 12:43:33 +1000 Subject: [PATCH] Orange Crab is 48MHz not 50MHz, bump PLL frequency I'm not sure why I set the input frequency for the Orange Crab to 50MHz. Since we easily make timing now, bump our output frequency to 48MHz as well.
