From mboxrd@z Thu Jan 1 00:00:00 1970 From: Patrick Delaunay Date: Tue, 28 Jul 2020 11:51:24 +0200 Subject: [PATCH v4 11/14] test: environment in ext4 In-Reply-To: <20200728095128.2363-1-patrick.delaunay@st.com> References: <20200728095128.2363-1-patrick.delaunay@st.com> Message-ID: <20200728095128.2363-12-patrick.delaunay@st.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Add basic test to persistent environment in ext4: save and load in host ext4 file 'uboot.env'. On first execution an empty EXT4 file system is created in persistent data dir: env.ext4.img.
