Hi, i am facing this problem that i could not seek proper code to get it to run..

OEM mtd @ booting from primary

i tried several methods with no luck

Can you help me correct dts spi node and generating image code?

Seeing that "FIS directory" and "RedBoot config" share the same erase block You can try to mimic jjPlus JA76PF2 image recipe: https://git.openwrt.org/?p=openwrt/openwrt.git;a=blob;f=target/linux/ath79/image/generic.mk#l1676, just drop DEVICE_COMPAT_* variables and adjust IMAGE_SIZE to the size of image1 and image2 combined. You'll find the SPI flash node in the dts (https://git.openwrt.org/?p=openwrt/openwrt.git;a=blob;f=target/linux/ath79/dts/ar7161_jjplus_ja76pf2.dts#l114) for the device, adjust the last three partitions to Your layout. Remember to backup flash contents before writing any image and use initramfs image to asses if there's no issues with Your modified layout.
Show Your resulting code changes before writing image to the flash, then I can check it for errors.

Thank you for your reply,
i did try this already
but i will try it again and post results .

i was getting syntax error when i use openwrt,ih-magic = <IH_MAGIC_OKLI>;

using

&spi {
	status = "okay";

	flash@0 {
		compatible = "jedec,spi-nor";
		reg = <0>;
		spi-max-frequency = <25000000>;

		partitions {
			compatible = "fixed-partitions";
			#address-cells = <1>;
			#size-cells = <1>;

			partition@0 {
				label = "RedBoot";
				reg = <0x000000 0x040000>;
				read-only;
			};

			partition@40000 {
				label = "loader";
				reg = <0x040000 0x020000>;
			};

			partition@60000 {
				label = "firmware";
				reg = <0x060000 0xe00000>;
				compatible = "openwrt,uimage", "denx,uimage";
				openwrt,ih-magic = <IH_MAGIC_OKLI>;
			};
				
			partition@fe0000 {
				label = "FIS directory";
				reg = <0xfe0000 0x00f000>;
				read-only;
			};

			partition@fef000 {
				label = "RedBoot config";
				reg = <0xfef000 0x001000>;

			bdcfg:	partition@ff0000 {

				reg = <0xff0000 0x010000>;

	};

actually i was trying with different image size as i was using all size between 0x60000 to the beginning of FIS directory

I thought it might be this, but after i followed what you told me, total image size is 0x700000 + 0x700000

as i already have 2 devices i am ready to write data to one of them.. and already writing it to Image1 partition

loader to be written with it's actual size on the whole partition area.
and firmware.bin to be written after 0x20000 from the beginning of image1 partition

@ 0xBF060000

so writing loader @ 0xBF040000
and firmware @ 0xBF060000

Any idea ?

It's because Your dts doesn't have #include <dt-bindings/mtd/partitions/uimage.h> in the includes section.

Going back to partition table it should look like this:

&spi {
	status = "okay";

	flash@0 {
		compatible = "jedec,spi-nor";
		reg = <0>;
		spi-max-frequency = <25000000>;

		partitions {
			compatible = "fixed-partitions";
			#address-cells = <1>;
			#size-cells = <1>;

			partition@0 {
				label = "RedBoot";
				reg = <0x000000 0x040000>;
				read-only;
			};

			partition@40000 {
				label = "loader";
				reg = <0x040000 0x020000>;
			};

			partition@60000 {
				label = "firmware";
				reg = <0x060000 0xde0000>;
				compatible = "openwrt,uimage", "denx,uimage";
				openwrt,ih-magic = <IH_MAGIC_OKLI>;
			};
				
			partition@e40000 {
				label = "nvram";
				reg = <0xe40000 0x010000>;
				read-only;
			};

			partition@fe0000 {
				label = "FIS directory";
				reg = <0xfe0000 0x00f000>;
				read-only;
			};

			partition@fef000 {
				label = "RedBoot config";
				reg = <0xfef000 0x001000>;
				read-only;
			};

			bdcfg: partition@ff0000 {
				label = "bdcfg";
				reg = <0xff0000 0x010000>;
				read-only;
			};
		};
	};
};

I forgot to mention that "firmware" partition should have subtracted 0x20000 of "loader" partition. That means also IMAGE_SIZE needs to be reduced to 14208k.
What is stored in "nvram" partition?

Yes Thank you.. this fixed it. and firmware partition upon loading is now spliting and creating mtd partitions..

i was aware of that, thank you very much.

OEM WiFi configuration this is the data @ start of nvram partition

HSLF..e.!.#.=-.ywebredir/
whiteurl154=.wlan1_9/
keyid=0.wlan0_6/
nat=1.wlan0_8/
hiddenssid=0.wlan0_9/
acl=0.webredir/
whiteurl155=.wlan1_8/
ssid=Wireless.wlan1_3/
encryptkey=none.wlan1_0/
assoccount=0.wlan1/
freqspec=24.wlan1/
wmm_sta_bk_cwmax=10.wlan0_5/
securityprofilename=Profile7.webredir/
whiteurl156=.wlan0_8/
wmm=1.wlan0_10/
wmm=1.webredir/
and so on .................. whitelist URLs and bunch of settings related to OEM firmware.

Also for jffs2 partitions
0xf70000 0x60000
0xf80000 0x60000

OEM logs are stored there, for this device with dual boot, so they are 2 separate partitions

S0004 root: system Cold Start
S0007 root: system Cold Start
S0024 root: system Admin Restart [172.30.8.1, httpd]

so i think i can make firmware partition occupy the whole size between 0x60000 after loader partition.
and up to 0xfe0000 the starting of FIS directory..

Now for these errors

[    6.253936] OF: Bad cell count for /spi@1f000000/flash@0/partitions
[    6.260200] OF: Bad cell count for /spi@1f000000/flash@0/partitions

[    6.273923] OF: Bad cell count for /spi@1f000000/flash@0/partitions

i tried to add in dts file the 3 partitions nvram jffs2 jffs2
as nvram oem1 oem2 i though it might fix this up.

but with no luck

now my dts spi node is

&spi {
	status = "okay";

	flash@0 {
		compatible = "jedec,spi-nor";
		reg = <0>;
		spi-max-frequency = <25000000>;

			compatible = "fixed-partitions";
			#address-cells = <1>;
			#size-cells = <1>;

			partition@0 {

				read-only;
			};

			partition@40000 {
				label = "loader";
				reg = <0x040000 0x020000>;
			};

			partition@60000 {
				label = "firmware";
				reg = <0x060000 0xf80000>;
				compatible = "openwrt,uimage", "denx,uimage";
				openwrt,ih-magic = <IH_MAGIC_OKLI>;
			};
										
			partition@fe0000 {
				label = "FIS directory";
				reg = <0xfe0000 0x00f000>;
				read-only;
			};

			partition@fef000 {
				label = "RedBoot config";
				reg = <0xfef000 0x001000>;
				read-only;
			};

			bdcfg:	partition@ff0000 {

what do you think ?

With assumption most crucial data is stored in "bdcfg" partition, like MAC address or calibration data.
Could these values in "nvram" partition be re-created by OEM firmware, then it can be safely assigned to "firmware" partition. If You don't plan to ever go back to original firmware, then it's not worth to keep it.

This is usually read-write, so if it's only storing logs it can safely be assigned to "firmware" partition. If "nvram" will be kept, there's mtd-concat option, I don't remember if it's only for two separate flash chips or if it can be used to join two separate partitions. Check examples in other dts.

You can safely ignore those, I think this was problem with cell hierarchy enumeration in kernel drivers, probably fixed in 5.15 OpenWrt kernel.

Bootlog looks good, overlay properly initiated, so You're good to go.
