Hi,
We've got a Freescale 2012 sabreauto custom board , where we've mounted a IC FLASH 64GBIT 48TSOP NAND chip ( Mfg ID -MT29F64G08CFACAWP:C TR). We cannot, however, seem to find an existing i.MX6 board that uses any chips like this. The NAND chip is working under u-boot as I can Erase/Read/Write the chip. But Linux is unable to load the NAND driver successfully.
Here are my dtsi settings:
imx6qdl-sabreauto.dtsi :-
&ecspi1 {
fsl,spi-num-chipselects = <1>;
cs-gpios = <&gpio3 19 0>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_ecspi1 &pinctrl_ecspi1_cs>;
status = "disabled"; /* pin conflict with WEIM NOR */
flash: m25p80@0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "st,m25p32";
spi-max-frequency = <20000000>;
reg = <0>;
};
};
&gpmi {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_gpmi_nand>;
status = "okay"; /* pin conflict with uart3 */
nand-on-flash-bbt;
};
&weim {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_weim_nor &pinctrl_weim_cs0>;
#address-cells = <2>;
#size-cells = <1>;
ranges = <0 0 0x08000000 0x08000000>;
status = "disabled"; /* pin conflict with SPI NOR */
nor@0,0 {
compatible = "cfi-flash";
reg = <0 0 0x02000000>;
#address-cells = <1>;
#size-cells = <1>;
bank-width = <2>;
fsl,weim-cs-timing = <0x00620081 0x00000001 0x1c022000
0x0000c000 0x1404a38e 0x00000000>;
};
};
Can you please help us to solve the NAND issue in linux?
Thanks In Advance.
