From 2bf3359ea5555972bcd6684f1c3142e2b7200281 Mon Sep 17 00:00:00 2001 From: Troy Kisky Date: Tue, 7 Feb 2012 14:08:50 +0000 Subject: i.mx6q: mx6qsabrelite: Update the network configuration Define CONFIG_PHY_MICREL, and minimize the tx clock delay. There is an issue with 1000 baseTx mode on early revs of the SabreLite boards. The center tap pin 9 of the mag RJ45 USB combo was connected to the 3.3 filtered supply. Letting this pin float solved the problem. Symptoms of the problem were packets with many extra zeroes tacked on the end, and random bit flips causing a high rate of CRC errors. 10/100 baseTx worked fine on all revs. To disable 1000 baseTx for these boards, simply define the environment variable disable_giga. ie. setenv disable_giga 1 Signed-off-by: Troy Kisky Acked-by: Dirk Behme --- include/configs/mx6qsabrelite.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'include') diff --git a/include/configs/mx6qsabrelite.h b/include/configs/mx6qsabrelite.h index 8a95af91cc..982f03f710 100644 --- a/include/configs/mx6qsabrelite.h +++ b/include/configs/mx6qsabrelite.h @@ -77,6 +77,8 @@ #define CONFIG_FEC_XCV_TYPE RGMII #define CONFIG_ETHPRIME "FEC" #define CONFIG_FEC_MXC_PHYADDR 6 +#define CONFIG_PHYLIB +#define CONFIG_PHY_MICREL /* allow to overwrite serial and ethaddr */ #define CONFIG_ENV_OVERWRITE -- cgit v1.2.1
