imx6dl Parallel NOR Partition

zhilinhuang — Mon, 04 Sep 2017 11:58:04 GMT

Dear engineers！

Board environment:
L4.1.15_2.0.0_ga
yocto
imx6dl
Parallel NOR 128m

My equipment storage nor flash is 128M,（imx6dl）

I would like to uboot kernlel dts and rootfs how to write nor flash

The ucl.xml only has the example of programming uboot, no kernle, dts and rootfs, what should I modify to make it support burning these files

ucl.xml ：

<LIST name="Nor Flash" desc="Choose Nor flash as media">

My dts ：

#include "imx6q-sabreauto.dts"

&ecspi1 {
/* pin conflict with weim */
status = "disabled";
};

&can2 {
/* max7310_c on i2c3 is gone */
status = "disabled";
};

&gpmi {
status = "okay";
};

&i2c3 {
/* pin conflict with weim */
status = "disabled";
};

&uart3 {
/* pin conflict with gpmi and weim */
status = "disabled";
};

&usbh1 {
/* max7310_b on i2c3 is gone */
status = "disabled";
};

&usbotg {
/* max7310_c on i2c3 is gone */
status = "okay";
dr_mode = "peripheral";
};

&weim {
pinctrl-assert-gpios = <&gpio5 4 GPIO_ACTIVE_LOW>;
status = "okay";
};

英文不是很好，抱歉。就是修改什么地方支持把，uboot ，kernel ，dts，rootfs 烧写到 Parallel NOR 128M 中。

Thank you, look forward to your reply!

Hello Zhilin Huang,

The script for NOR flash just loads the boot loader but you may take the script for other memories as example to fit your needs.

There is some more information on the Manufacturing Tool V2 UCL User Guide, available along the manufacturing tool as part of the documentation of the tool. I hope this helps!
