From a2cdf9a95fea33ade5c608885424d6aae21773f5 Mon Sep 17 00:00:00 2001 From: iabdalkader Date: Sun, 1 Dec 2024 08:58:24 +0100 Subject: [PATCH] renesas-ra/mpconfigport: Switch FATFS LFN to type 2. LFN type 2 uses the stack to allocate the internal working buffer for LFN, which is thread-safe and saves about 512 bytes of BSS memory (at the expense of needing that much memory on the stack).
