Hello,
I have a custom board that uses S29GL01GS Parallel NOR flash (128 MB) connected to imx6q processor through EIM bus.
While booting I get the following error :
of-flash 8000000.nor: do_map_probe() failed
My linux kernel is 3.14.1.1.
This is my device tree configuration:
&weim {
compatible = "fsl,imx6q-weim";
reg = <0x021b8000 0x4000>;
clocks = <&clks IMX6QDL_CLK_EIM_SLOW>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_weim_nor_2 &pinctrl_weim_cs0_2>;
#address-cells = <2>;//see below:1 cell for 4 hex digits
#size-cells = <1>;
ranges = <0 0 0x08000000 0x08000000>;
status = "okay";
nor@0,0 {
compatible = "cfi-flash";
reg = <0 0 0x04000000>;
#address-cells = <1>;
#size-cells = <1>;
bank-width = <2>;
fsl,weim-cs-timing = <0x10610281 0x00000001 0x0b020000
0x00008000 0x1c000000 0x00000000>;
};
};
Is there any patch to support this NOR flash?
Thanks and regards,
Sumish

Hi Sumish,
There is no patch needed for the GL01GS.
You could attach a logic analyzer and take a look at the bus signals.
Please let me know if you need any further assistance on this.
Thanks and Regards,
