The garbage guy entertained himself, stepped on the pit, and updated the WIA3300-10 firmware to the master_24.x branch

Heart of Canaan

I'm an amateur garbage guy myself, my level is extremely poor, my skills are none, I'm older, and I can't speak clearly. It is inevitable that there will be mistakes in the article, and the bigwigs are asked to correct them.

1. Brief introduction:

This batch of WIA3300-10 was eliminated by Telecom, and it didn't even give the power supply, the POE power supply, and all the power supply capacitors exploded. I replaced the capacitor.

Old and frail, hands trembling and eyes slanting, just look at it.


The red circle is the replaced capacitor.



The holes in place the fins are as clean as my wallet.

2. Analyze the original firmware and previous data.
The following information is emphatically referenced:
Siga Spruce wia3300-10, disassembled and adapted to Breed/openwrt firmware, has been completed without disassembly!! -Wireless router hardware transformation and fault repair-Enshan Wireless Forum
Siga Spruce WIA3300-10 OpenWrt 2024-03-31 Update 5.10 Kernel-OPENWRT Special Edition-Enshan Wireless Forum

Special thankshackpascal, Although this older guy doesn't post much, each one is a phenomenal blockbuster post.
Special thanks vb1980, he open-sourced the WIA3300-10 source code based on immort 5.10.

Analysis of the data revealed that:

• At present, breed is available, it is based on K2P modification, but it is not perfect, but it can be called up.
• At present, the LED support of unofficial firmware is not perfect, mainly due to the lack of GPIO_LED information.
• The dts file needs to be created, and the GPIO information, partition information, and network interface order need to be supplemented.
• ./target/linux/ramips/image/mt7621.mk
• ./target/linux/ramips/mt7621/base-files/etc/board.d/01_led need to add an LED behavior definition.
  

At this time, I was very optimistic, but I didn't know that every step was a pit. The configuration file is not exactly the same between different versions of OpenWRT, and the difference between 5.x and 6.x is quite large.

I started by adding the device information in the MT7621.mk.
This is plagiarized from D2, but it was a shameful failure, so the first half copied the definition of the VB1980 big guy, and the second half copied NEWIFI_D2. Even so, because the old eyes are dizzy, a "-" is missing, causing the wireless function to disappear............

This paragraph is the configuration file currently in use.,There are still some problems.,I hope the big guys can point it out.。

define Device/skspruce_wia3300-10
  $(Device/dsa-migration)
  IMAGE_SIZE := 32448k
  DEVICE_VENDOR := Skspruce
  DEVICE_MODEL := WIA3300-10
  SUPPORTED_DEVICES += wia3300-10
  DEVICE_PACKAGES := kmod-mt7615-firmware kmod-usb3 kmod-usb-ledtrig-usbport -uboot-envtools
endef
TARGET_DEVICES += skspruce_wia3300-10

Next, I was going to generate a .dts file, I needed to look for GPIO_LED information, and by analyzing the factory firmware, I found that the factory firmware did not seem to have the "LED configuration" option. Or maybe I'm not looking for the place. However, there is a configuration file in the original firmware, and I flipped through all the files containing "LED", and finally learned that the GPIO_LED configuration of the WIA3300-10 is as follows:

                gpo_boot=23 - Boot LED (Red)；
                gpo_power=24  - Power LED (Green)；
                gpo_wan=3 - WAN LED (Green)；
                gpo_5g=22 - WiFi 5g LED(Blue)
                gpo_2g=4- WiFi 2.4g LED (Green)
These lines of text took me 4 weeks. But I didn't know it at this time, I had already stepped into the pit with one foot.
At this time, I did not have the ability to verify the GPIO_LED in breed, so I could only verify it by repeatedly modifying, compiling, and flashing the firmware, but I didn't know that the "wia3300-10 breed" modified by K2P's breed had a big pitfall, which would cause the LED to behave as expected.
The dts file of K2P is not completely suitable for modifying the dts file of WIA3300-10, in fact, the most suitable for patchwork is newifi-d2 and youhua-wr1200js. The former provides a reference for bus device initialization, and the latter provides a reference for the network part. It took another 3 days to change llllw to wllll, and 2 days to change the partition.

This is the DTS file currently in use.,It's still imperfect.,I hope the bigwigs can correct it.。

The behavior of LED lights can be influenced by breeds.
I put the led behavior profile in the ./target/linux/ramips/mt7621/base-files/etc/board.d/01_led file, as for why I put it here, the main reason is to facilitate the modification of the LED configuration on the uci interface (in fact, it is copied).
Current LED configuration

skspruce,wia3300-10)
        ucidef_set_led_netdev "wan" "INTERNET" "internet:green" "wan" "link tx rx"
        ucidef_set_led_netdev "wifi5g" "5G" "wlan5g:blue" "phy1-ap0" "link tx rx"
        ucidef_set_led_netdev "wifi2g" "2G" "wlan2g:green" "phy0-ap0" "link tx rx"
        ;;


Some of my whimsical ideas: regarding the power_led and the boot_led, one of the two lights is red and the other is green, unified packaging, I considered configuring the power_led_red to blink in heartbeat to reflect the CPU load, boot_led_green to turn off after the system boot is complete, or to set it to reverse the heartbeat beat to reflect the energy consumption along with the red light.

However, it was only at this point that I had the knowledge to modify GPIO_LED level parameters in Breed. This was supposed to be done at the beginning.
Reference:【2022-07-26】AR/QCA/MTK Breed, Powerful Multi-threaded Bootloader-OPENWRT Special Edition-Enshan Wireless Forum
Enter the breed environment and command line telnet 192.168.1.1
Execute the command gpio list to get a bunch of information, refer to the previous GPIO_LED file, and sort out the useful ones:

PIO    direction   status  name
3       out         hi      wlan5g
4       out         hi      internet
18      in          hi      reset
22      in          hi
23      out         hi      wlan2g
24      out         hi      power
As you can see, the error is still quite obvious.
Use the gpio dir set 22 out command to modify the direction of the 22-port GPIO.
The final changes should look like this:

3       out         hi      
4       out         hi      
18      in          hi      
22      out         hi
23      out         hi      
24      out         hi      

At this point, you should know how to compile your own firmware

The WIA3300-10 on the small yellow croaker sells for 30 yuan a piece, and it is still in Iraqi condition. It's better to buy a Xiaomi CR660X for 35 yuan

It's that I didn't make it clear, this batch was deployed by the telecom company to my unit, because of the problem of power supply, which led to the capacitance of more than 20 pieces of equipment bursting, so the telecom company came to replace it with a new one, and these more than 20 units were scrapped and did not incur costs.

Let's study the big guys

The WIA3300-10 is also a classic, and I have used more than 40 of them, most of which are second-hand disassembled and a few are brand new. The main disadvantage is the capacitor, no matter how good the color is, there will always be a capacitor that will burst after a period of time. I'm all POE power supply, it's the 63V capacitor that explodes, I encounter a few bursting capacitors, anyway, the POE doesn't light up, I change the 12V power supply to light up, that is, the 63V capacitor is blown up, and it can return to normal if you change it.

Then again, the MT7621 router, if you simply do routing, AP, and don't use any special plug-ins, it's really easy to adapt and compile a pure version of Padavan by yourself.

I have dozens of them too! After swiping the firmware, the wireless is under the same name (the same is true for different names), and the 5G wireless will refuse to access! The radio should be set to automatic for it to work!! Everything else is working fine!! Count the Wia3300-10 as a good third-party firmware！！ I hope that the landlord will adapt to the Padavan firmware, but I have failed to adapt to Padavan all of them

For reference:"https://github.com/search?q=wia3300-10&type=codeIt's because GH is full of PD firmware, and there is no OP firmware, so I have to compile it myself.

The firmware on GH is basically available in this forum, and it is all contributed by several bigwigs of the forum.

It's the original model, and it's good to place an order for the same model in Jialichuang.
