Hi,
As question above, this issue actually hardly with me. So I hope someone can help me.
I trying to flash U-boot, zImage, .dts file and rootfs into QSPI. And I'm using mfgtools. So the problem is when I read ucl2.xml, in part QSPI Nor Flash, this tool is flash only .imx file and header file.
Then, I check mtd partition in Linux command line:
$ cat /proc/mtd
mtd0: 02000000 00010000 "21e0000.qspi"
It's show me only one part is mtd0 with size 32Mb. Then I try to customize the device tree file and devide it into 4 parts.
&qspi {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_qspi>;
status = "okay";
ddrsmp=<0>;
flash0: n25q256a@0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "micron,n25q256a";
spi-max-frequency = <29000000>;
spi-nor,ddr-quad-read-dummy = <6>;
reg = <0>;
partition@0 {
/* 1M for Uboot */
reg = <0x00000000 0x00100000>;
label = "uboot";
};
partition@1 {
/* 8M for kernel- zImage */
reg = <0x00100000 0x00800000>;
label = "kernel";
};
partition@2 {
/* 1M for device tree */
reg = <0x00800000 0x00100000>;
label = "dts";
};
partition@3 {
/* 20M for root file system */
reg = <0x00900000 0x01400000>;
label = "rootfs";
};
};
};
And I execute again this command:
$ cat /proc/mtd
dev: size erasesize name
mtd0: 00100000 00010000 "uboot"
mtd1: 00800000 00010000 "kernel"
mtd2: 00100000 00010000 "dts"
mtd3: 01400000 00010000 "rootfs"
Okay, It's seem be right. But when I access uboot environment and check with:
$ printenv

And I can not found mtdparts environment. Then I try execute this command to add mtdparts environment:
$ setenv mtdparts mtdparts=21e0000.qspi:1m(uboot),8m(kernel),1m(dtb),20(rootfs)
Then I check with command:
$ printenv mtdparts
mtdparts=mtdparts=21e0000.qspi:1m(uboot),8m(kernel),1m(dtb),20(rootfs)
Next step, I customize the ucl2.xml to flash all 4 parts above. <In attached file below>
But I got error with:
UTP: received command '$ flash_erase /dev/mtd1 0 20'
UTP: executing "flash_erase /dev/mtd1 0 20"
flash_erase: error!: /dev/mtd1
error 2 (No such file or directory)
UTP: sending Non-success to kernel for command $ flash_erase /dev/mtd1 0 20.
utp_poll: exit with status 65280
This mean I do something wrong in partition. May I only partition in kernel but actually in default It still one partition is mtd0.
Someone can help me ?
Thank you so much,
Toan
