i have a phicom router with 32Mb of space and ram is also higher space value(sorry really forgot about detail about ram) so my problem is that when i flash my router with openwrt it only detect 16mb of flash and some goes for the ram it doesn't detect the hole ram and rom that is present on the board is because of the build for raimps type kernel were written for 16mb flash rom .
so is there a way to make change in kernel file to i can use my extra space.
so do i have to board porting or kernel porting to get my build to detect 32 mb flash
Would you mind telling us which Phicomm router exactly?
yes sure its
mt7621
You are funny

The only supported Phicomm with MT7621 is called Phicomm K2P!
According to [1], [2] and [3], this device does have 16 MB flash and 128 MB ram.
I believe this info is correct.
Can you post a picture of your 32 MB flash chip and your bigger ram?
[1] https://openwrt.org/toh/phicomm/phicomm_k2p_ke2p
[2] https://github.com/openwrt/openwrt/blob/master/target/linux/ramips/dts/mt7621_phicomm_k2p.dts
[3] http://www.phicomm.com/cn/en.php/News/detail/cateid/2/id/435.html
At least the last reference should be correct.
Juppin don't shoot the messenger 
i am just passing the information exactly how my friend has describe it
this is his word not mine
he say that when he is using breed via UART cable it detect it 32 MB of flash
no please could anyone tell how to increase flash through kernel porting ?
this the screenshot you requested
this the breed web
this is router after flash :-
this is router Ram :-
Sorry, I do not trust a closed source software like breed.
I asked you to post pictures of the chips on the mainboard.
I don't know why Linux shouldn't detect the ram size automatically.
There is a patch for automatic memory detection on mt7621.
If your friend has soldered a bigger flash memory, than this change has to be reflected in the device tree of this device (device tree of K2P is linked in my previous post) to have this additional space available.

wait i will send the chip set photo
Ok, so your friend has soldered this flash chip on his K2P?
If you want to increase the usable size for OpenWRT, one has to increase the firmware partition inside the device tree and optional the size definition in the image Makefile.
Can you please also provide the output of the command dmesg?
I think, because the firmware partition is the last partition, it should be possible that it gets increased by the mtd subsystem without modifying the device tree firmware partition definition here.
hi there juppin after applying this patch it still don't show any changes this the output screenshot
so Juppin after look at the link what do i have do in my build to get more space in my flash
and few thing i did understand mtd subsystem
ps :-
i am using v18.06.5 for my build because it does't cause reboot issue
If you've replaced the chips with larger ones you have to modify the dts file and rebuild, or otherwise somehow attach a new "of" (compiled dts) blob to the kernel.
OpenWrt has been moving to the dts model where both the flash and RAM sizes are hard-coded rather than probed and dynamically allocated.

This patch is already part of the OpenWRT kernel for mt7621 on master/snapshot and on 19.07, but not on 18.06.
But you got me wrong... This is only for auto detection of the ram size.
As @mk24 said, for a bigger flash, you have to edit the dts file for your K2P.
But I asked you to post the full output of the dmesg command as text after booting up your K2P, because on other targets, I've seen that the partition is automatically increased if there is more flash and if it's the last partition, as it your K2P has.
Change this line:
From:
reg = <0xa0000 0xf60000>;
To:
reg = <0xa0000 0x1f60000>;
And you will use the full 32M of your bigger flash chip.

thank you Mk24 i will get down your method and juppin sorry for the late reply i will forward the dmesg log screenshot
Thank you juppin and MK24 for help me out the suggested method did it charm on the router my flash has increase to 32 MB.
the only things is that left is that my ram hasn't increase so do i have to change in dts as well file
this the full dmesg log :-

ps :- thank again Juppin and Mk24
i know my problem has been solved but i want to know what does 1f6000 mean in blow script change you mentioned ?
reg = <0xa0000 0xf60000>;
To:
reg = <0xa0000 0x1f60000>;
The first value is the start address and the second value is the size of the partition.
Both values are in hexadecimal representation.
The additional 0x1000000 bytes are exactly 16 MB.
Regarding your ram size, this should be solved with a update to 19.07 or to snapshot builds, as there is support for ram size auto detection.
If you want to stay on 18.06, you have to double the value in the device tree.
From:
reg = <0x0 0x8000000>;
To:
reg = <0x0 0x10000000>;
