From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jakob Unterwurzacher Date: Wed, 6 Jun 2018 12:19:03 +0200 Subject: [U-Boot] [PATCH] rockchip: board: lion-rk3368: increase phy autonegotiation timeout Message-ID: <20180606101903.31626-1-jakob.unterwurzacher@theobroma-systems.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de The first dhcp command consistently fails with a timeout when the lion-rk3368 board is connected to a Zyxel GS1100-24E Gigabit Ethernet switch: ethernet at ff290000 Waiting for PHY auto negotiation to complete......... TIMEOUT ! Increasing PHY_ANEG_TIMEOUT from the default 4000 to 8000 makes the first dhcp command work reliably.
