From f8b664b727563ef755fc64eb85894799fc16e37a Mon Sep 17 00:00:00 2001 From: Gregory Nutt Date: Sun, 15 Mar 2015 09:35:48 -0600 Subject: [PATCH] SAMA5: Fix a bug in SAMA5 HSMCI. The bitfield mask and shift values were reversed resulting in a trashed value for the number of blocks in the BLOCKR register. This was sufficient to prevent DMA writes from working. --- configs/sama5d3-xplained/README.txt | 3 +++ configs/sama5d3x-ek/README.txt | 3 +++ 2 files changed, 6 insertions(+) diff --git a/configs/sama5d3-xplained/README.txt b/configs/sama5d3-xplained/README.txt index 29c59a2965..258bb3ed94 100644 --- a/configs/sama5d3-xplained/README.txt +++ b/configs/sama5d3-xplained/README.txt @@ -3168,6 +3168,9 @@ To-Do List the SAMA5D4 which has a different DMA subsystem).

That format works fine with Linux, but does not appear to work with Windows. Reformatting on Windows can resolve this.
