This is the source code, correct? If so can, can you get the information you need from there?
If not, I have a USB to serial used for some Arduino-based projects, and am more than willing to sacrifice my device. Just let me know how to get the bootlog. Is it something like connecting the device to my PC through the dongle, and open serial monitor?
i'm not a developer, but afaik without a working serial connection we are flying blind; at first we need to find the UART/TX signal on the board.
Assuming that the GPL code posted by tp-link has anything in common with the actual firmware running in our devices, the u-boot uses GPIO18 and GPIO22 for UART (u-boot/include/config.h: UART_RX18_TX22); this doesn't mean much, as the mapping pin x GPIO is not public
I was working on getting the booting log through UART. Upon inspection I did find that R64 & R69 were missing, and that should they be shorted, will connect the header to the MCU. However, I did bridge them and try to connect to the UART and failed. I tried to connect a serial terminal to the MCU but couldn't get anything from it, even after switching the RX and TX pins.
Anyhow, glad they found a solution and that R64 and R69 were indeed key factor in the UART communication. I wonder why my UART attempt failed. Could R64 and R69 require a specific value, and not bridging them with 0 ohm?
Anyhow, I got the device to test it. Question is, I don't know how to compile the code into a working firmware, so if you can take care of that, I can do the testing.
i'm sorry to hear about your device
unfortunately i no longer have a 450v2
if your router is stuck in the boot process (blinking power led indefinitely), afaik you could try to either solder two resistors and get access to UART, or remove the flash chip and program it externally
Hi
I got acess ssh, but firmware dont have luci, i search tutorial of how install luci off line in RE450 but without sucess, How install luci offline in RE450v2
hello there! I've just got this unit and wanted to report that the current snapshot build works just fine. It's true that it doesn't ship with luci (as usual btw), but it's easy to install if you have a utp connection available.
This is my rough step by step:
to flash the image, I've connected the unit with the utp cable to my machine, it provided IP address via DHCP (your internet will go down on the machine due to the default route gets set to the RE450. it'll come back when you unplug).
the unit comes back online after a reboot with static ip address configured to 192.168.1.1, no root password.
You need to ssh to the unit and configure it to grab IP address via DHCP. See DumpAP tutorial. In brief, set /etc/config/network to:
Reboot the unit (unplug, plug). Pull the UTP cable from the machine and connect to your router. It'll provide ip address automatically. Check the router what address the RE450 got and ssh back to it.
in the ssh shell install luci:
opkg update
opkg install luci
Now you should have the minimal required luci webui access.
Note: I didn't need UART or any physical hacking around. Just pushed the snapshot image from factory webui.
Update: I've verified that both WiFi module works just great, over 2.4 GHz I got 300MBps and 5GHz with 866MBps.
