Signed-off-by: Igor Opaniuk <igor.opan...@toradex.com> --- v2: - Based on empirical results from Philippe Schenker, increased timeout value to 15s, just to be on the safe side include/configs/apalis_imx6.h | 1 + 1 file changed, 1 insertion(+) diff --git a/include/configs/apalis_imx6.h b/include/configs/apalis_imx6.h index 4b0a3fb26b..df31cf6fe7 100644 --- a/include/configs/apalis_imx6.h +++ b/include/configs/apalis_imx6.h @@ -58,6 +58,7 @@ #define IMX_FEC_BASE ENET_BASE_ADDR #define CONFIG_FEC_XCV_TYPE RGMII #define CONFIG_ETHPRIME "FEC" +#define PHY_ANEG_TIMEOUT 15000 /* PHY needs longer aneg time */ #define CONFIG_FEC_MXC_PHYADDR 6 #define CONFIG_TFTP_TSIZE -- 2.17.1 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
