How to create NOR partitions in T1040RDB

Suraj_Prakash · ‎10-28-2021

Hi

I have made the NOR partitions (in current bank and alternate banks) for the T1040RDB based on the image layout mentioned in QorIQ T1040 Reference Design Board Quick Start document.

But I was getting the following errors in the kernel log

Creating 6 MTD partitions on "fe8000000.nor":
0x0000e8020000-0x0000e86fffff : "NOR Linux-Image_1"

I also tried to read the nor location from uboot and log for the same is mentioned below

Please find attached Dts file.

Kindly suggest a solution.

Please modify the dts file as the following.

nor@0,0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "cfi-flash";
reg = <0x0 0x0 0x8000000>;
bank-width = <2>;
device-width = <1>;

partition@e8020000 {
/* 7.2MB for linux Image 1 */
reg = <0x20000 0x007e0000>;
label = "NOR Linux-Image_1";
};
partition@e8800000 {
/* 1MB for DTB 1 */
reg = <0x800000 0x00100000>;
label = "NOR DTB_1";
};
partition@e9300000 {

reg = <0x4020000 0x007e0000>;

};
};

Hi,

After making the above mentioned partitions I am facing errors while creating ubi partition on Nand

root@t1040d4rdb:~# mount -t ubifs ubi0:rootfs /mnt/rootfs
UBIFS error (ubi0:0 pid 1438): .ubifs_mount: too few LEBs (4), min. is 17
mount: wrong fs type, bad option, bad superblock on ubi0:rootfs,
missing codepage or helper program, or other error

In some cases useful info is found in syslog - try
dmesg | tail or so.

please suggest. Thanks in Advance

Please refer to UBIFS creation procedure in this thread
