Hi,
I'm building an image for my MR3420v1 that already upgraded the flash to 16/64.
After the image was build, I try to upload sysupgrade file to my router with breed.
After the image was uploaded, it's like always reboot and never enter the ssh console or luci.
But, when I upload initframfs kernel file, it's successfully boot and I can log in to the device.
Why is this happening? How to solve this issue?
Which version of OpenWrt?
What does the log show when it crashes?
Most likely you have an issue with the rootfs definition in the dts, or writing the roots is failing when you do the sysupgrade, but only the bootlog will show for sure
It's 21.02.1 version
I didn't get bootlog yet, because I'm still using ethernet connection, I can ping ke the device just a few seconds seems the uboot is working, but then disconnect again when try to load the firmware.
where is the file showing rootfs definition/dts?
since this router is normally in tiny/small flash section. So, I make some modification in these file so I can build 3420v1 generic version
$ git checkout v21.02.1
M target/linux/ath79/image/generic-tp-link.mk
M target/linux/ath79/image/tiny-tp-link.mk
M target/linux/ath79/tiny/target.mk
HEAD is now at b4d7885af7 OpenWrt v21.02.1: adjust config defaults
I suspect we are troubleshooting the same issue.
My Proroute H820 router isn't supported by OpenWrt yet. I have it booting fine with a dts and patches made for 19.07.8 and also when I load 21.02.1 image to SDRAM via TFTP.
Here is log when booting 21.02.1 from flash:

Thank you for your info.
I'm also noob in OpenWRT compile and build.
Let's us share useful info and tips.
Please help some insight...
Here are mtd partition when I'm in lede...
root@OpenWRT:~# cat /proc/mtd
dev: size erasesize name
mtd0: 00020000 00010000 "u-boot"
mtd1: 0014af80 00010000 "kernel"

mtd4: 00010000 00010000 "art"
mtd5: 00fd0000 00010000 "firmware"
Here are code on .dtsi file
flash@0 {
compatible = "jedec,spi-nor";
reg = <0>;
spi-max-frequency = <25000000>;
partitions {
compatible = "fixed-partitions";
#address-cells = <1>;
#size-cells = <1>;
uboot: partition@0 {
reg = <0x0 0x20000>;
label = "u-boot";
read-only;
};
partition@20000 {
compatible = "tplink,firmware";
reg = <0x20000 0x3d0000>;
label = "firmware";
};
partition@3f0000 {
reg = <0x3f0000 0x10000>;
label = "art";
read-only;
What need to add or modify partition?
I suspect your partitions are fine.
I am still investigating how to make progress. It could be we need to add something specific for our devices in the device profile.
For my Proroute H820 I added the following profile to rt305x.mk:
define Device/proroute_h820
SOC := rt5350
BLOCKSIZE := 4k
IMAGE_SIZE := 7872k
UIMAGE_NAME:= Linux Kernel Image
DEVICE_VENDOR := Proroute
DEVICE_MODEL := H820
DEVICE_PACKAGES := kmod-usb2
SUPPORTED_DEVICES += h820
endef
TARGET_DEVICES += proroute_h820
I'm currently searching for additional options to hopefully solve the problem.
I found it. 
I added $(Device/uimage-lzma-loader) to my device profile and it booted from flash:
define Device/proroute_h820
$(Device/uimage-lzma-loader)
SOC := rt5350
BLOCKSIZE := 4k
IMAGE_SIZE := 7872k
UIMAGE_NAME:= Linux Kernel Image
DEVICE_VENDOR := Proroute
DEVICE_MODEL := H820
DEVICE_PACKAGES := kmod-usb2
SUPPORTED_DEVICES += h820
endef
TARGET_DEVICES += proroute_h820
Glad to hear that... Good for you...
I also find the solution.
I copy the partition on my 2543ND to my 3420v1 router and it works
Here is the .dtsi file and make changes to .dtsi file,
partition@20000 {
compatible = "tplink,firmware";
reg = <0x20000 0xfe0000>;
label = "firmware";
};
partition@ff0000 {
reg = <0xff0000 0x10000>;
label = "art";
read-only;
Thank you
To get the bootlog you need to be connected via serial and then capture everything including the crash.
With a log you’re stabbing in the dark.
How are you booting the initramfs without a serial connection?
Yes, I understand that bootlog need to get serial connection. My usb to serial is still in my storage box and need to solder the connection, that is not my setup at the moment.
I'm using breed web to load the image.
Btw, thank you for .dts file idea, this is what I need...
I didn't know how expand the rootfs partition so sysupgrade image can be loaded.
The hex mathematics sound wrong.
You risk overwriting art.
Starting from 20000 with size fe0000 puts the partition end at 1000000 (or actually ffffff).
But art already starts from ff0000.
They overlap. Major risk of destroying the WiFi calibration data (= art).
You should have that size as 0xfd0000, so that art starting at ff0000 gets safely left alone.
reg = <0x20000 0xfd0000>;
Thank you for your correction, you're correct.
I did try 0xfe0000 before, but it's wrong.
I'll make correction.
Thank you
I've build the image, after flashing rootfs is in readonly.
Config is not saved after a reboot.
Is there any clue where to look at?
How to solve this issue?

I'll upload full bootlog if needed.
Well, grep the system log for "overlay" and "jffs2"
Your log extract stopped just before the interesting stuff.
Here are the remaining log

That is the kernel log. What about the system log? (logread)
Lots of errors regarding flash, CRC errors,crosslinked files etc.
Sounds like something is wrong. In the image?
