Linux/DRA725: UBI partition in NAND boot

Hi
can you share details about the UBI partition and how they are described in the kernel (via device tree vs command line)

Hi Srirama Govindarajan:

Thanks for your help.

Here is my UBI table.

My device tree

And I did some research these few days. I found the root cause of this situation might be the device tree partition.

Is that the device tree partition overlap the bootloader? Any suggestion? 

Thanks again.

Hi
You can refer to the illustrative partition mapping table described in the device tree definition file for DRA72x - under arch/arm/boot/dts/dra72-evm-common.dtsi

I have attached the snippet with the definition below for quick reference - you need to ensure your allocation matches with the table described in the device tree file

/* MTD partition table */
/* All SPL-* partitions are sized to minimal length
* which can be independently programmable. For
* NAND flash this is equal to size of erase-block */
#address-cells = <1>;
#size-cells = <1>;
partition@0 {
label = "NAND.SPL";
reg = <0x00000000 0x000020000>;
};
partition@1 {
label = "NAND.SPL.backup1";
reg = <0x00020000 0x00020000>;
};
partition@2 {
label = "NAND.SPL.backup2";
reg = <0x00040000 0x00020000>;
};
partition@3 {
label = "NAND.SPL.backup3";
reg = <0x00060000 0x00020000>;
};
partition@4 {
