Hi all. I want to install openwrt in Router Comfast wr617AC. This device has the characteristics:
but i do not know which firmware it could be? As I see on the openwrt website, it could be the TOTOLINK LR1200, but it has 5 ports and only 8 MB flash. Could i use this firmware?
attached images of the device

It looks like you're already running a vendor modified OpenWrt, so they should provide you with a GPL dump if you request it from them. Beyond that, you'll need to check actual hardware details to have support added. You cannot just try any image for models with the same SoC or amount of LAN ports.
See the OpenWrt wiki.
test with the firmware of router totolink lr1200, everything works fine but only detects 8MB in flash and device has 16MB. How cloud i change the DTS file for that 16MB is detected?
I would look at the *dts files for other mt7628 devices that have 16mb flash:
https://openwrt.org/tag/mt7628?do=showtag&tag=MT7628. The Netgear R6120 looks promising.
You may even be able to remove the usb code. Look at the difference between the two NetGear devices, the one with usb vs the one without usb.
I would also recommend working with a master git pull. It has actually been simplified and is the versions which accepts patches for new devices.
Question, should just I change it?
&spi0 {
status = "okay";
flash@0 {
compatible = "jedec,spi-nor";
reg = <0>;
spi-max-frequency = <40000000>;
partitions {
compatible = "fixed-partitions";
#address-cells = <1>;
#size-cells = <1>;
partition@0 {
label = "u-boot";
reg = <0x0 0x30000>;
read-only;
};
partition@30000 {
label = "u-boot-env";
reg = <0x30000 0x10000>;
read-only;
};
factory: partition@40000 {
label = "factory";
reg = <0x40000 0x10000>;
read-only;
};
partition@50000 {
compatible = "denx,uimage";
label = "firmware";
reg = <0x50000 0x7b0000>;
};
};
};
};
What I did was to copy the closest dts, in master, and rename it for my device. Then edit the remaining files.
For the Totolink, these were the pertinent files
https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=0ab9f283f75ad8314ad4be7c70d1397e9dbbfe15
I would also review master on git for the netgear 6120
Then build and use u-boot option 4 to test the initramfs image and check the leds and port numbering. Adjust your build if necessary. Once the image tests correctly, then install.
hi i have tried with dts file, but i cannot increase the memory flash /overlay for install more package. could anybody help me?
If possible, revert to the original firmware and review the kernel log (dmesg). It will contain the manufacturers partitioning. It is important to preserve u-boot, u-boot-env at the beginning and the firmware at the end.
If you cannot pull the factory partition, this looks pretty close:
https://git.openwrt.org/?p=openwrt/openwrt.git;a=blob;f=target/linux/ramips/dts/mt7628an_widora_neo-16m.dts;h=f17559f0eada5f2904faf90d825d9443c1000208;hb=HEAD
Hi shep, dmesg show next:
[ 0.670000] Creating 5 MTD partitions on "spi32766.0":

[ 0.800000] 0x0000007b0000-0x0000007f0000 : "configs"
How could I change the dts file with this information?
You can extract the partition info in a more readable format with cat /proc/mtd
https://openwrt.org/docs/techref/bootloader/uboot.config#example_of_configuring_uboot-envtools
The first 4 partitions in the *dts and dmesg match:
partition@30000 { label = "u-boot-env"; reg = <0x0 0x30000>; read-only; };
[ 0.680000] 0x000000000000-0x000000030000 : "u-boot"
and
partition@30000 { label = "u-boot-env"; reg = <0x30000 0x10000>; read-only; };
[ 0.680000] 0x000000030000-0x000000040000 : "u-boot-env" (0x30000 incremented by 0x10000
-> 0x40000)
Comfast's dmesg additionally has "kernel" "rootfs" and "config" partitions that I think are overlays and seem to match the link above. Note the size/erasesize are different in the link.
