From fd2a89b20ba66d76929f672b03f392733fb1b2a6 Mon Sep 17 00:00:00 2001 From: Przemyslaw Marczak Date: Fri, 18 Apr 2014 09:48:25 +0200 Subject: [PATCH] usb:gadget:f_thor: fix write to filesystem by add dfu_flush() Since dfu read/write operations needs to be flushed manually, writing to filesystem on MMC by thor was broken. MMC raw write actually is working fine because current dfu_flush() function writes filesystem only. This commit adds dfu_flush() to f_thor and now filesystem write is working. This change was tested on Trats2 board.
