Hi all,

ngisp · ‎09-18-2014

I am trying to port kernel 3.10 for custom board. I have added file in imx6q-XXX.dts and imx6qdl-XXX.dtsi . Also a defconfig for same has been added to arch/arm/configs/XXX_defconfig. Files I modified are

1) arch/arm/boot/dts/Makefile for

+ imx6q-XXX.dtb \

+ imx6q-XXX-hdcp.dtb \

+ imx6q-XXX-ldo.dtb \

+ imx6dl-XXX.dtb \

+ imx6dl-XXX-hdcp.dtb \

+ imx6dl-XXX-ldo.dtb \

2) arch/arm/boot/dts/imx6qdl.dtsi for MMC Card to take file system from mmc card.

usdhc1 {

pinctrl_usdhc1_1: usdhc1grp-1 {

fsl,pins = <

MX6QDL_PAD_SD1_CMD__SD1_CMD 0x17071

MX6QDL_PAD_SD1_CLK__SD1_CLK 0x10071

MX6QDL_PAD_SD1_DAT0__SD1_DATA0 0x17071

MX6QDL_PAD_SD1_DAT1__SD1_DATA1 0x17071

MX6QDL_PAD_SD1_DAT2__SD1_DATA2 0x17071

MX6QDL_PAD_SD1_DAT3__SD1_DATA3 0x17071

MX6QDL_PAD_ENET_TXD1__GPIO1_IO29 0x17071

>;

};

which gives the respective imx6q-XXX.dtb file . I am able to boot the board successfully (uart and ethernet is fine too) . However i am getting few error continuously. Below is log for same :-
