Any way to flash modified firmware via UART? #7

Closed andywei1996 closed 1 year ago

andywei1996 commented 1 year ago

Hi, thanks for this good repo! Unfortunately, I’ve updated my S1E to 2.6.0 version before I found this repo and I can’t get a telnet access to the panel now. I’ve followed the instruction in telnet.md document and removed the password successfully, next step is flash modified firmware into S1E, but my S1E can’t establish WiFi connection in this state so I can’t run command to download shell scripts and performing a firmware modify. So now I would like to know is there any way to flash the modified firmware to S1E? Is it possible to do this with UART? Thanks!

Did you restart S1E after remove the password?

After S1E restart, it shall automatically connect to WiFi AP.

andywei1996 commented 1 year ago

@niceboygithub Yes I reboot S1E after remove the password. I reboot S1E by remove the 5V power and reconnect it.

Did you finish provision it with Aqara Home app?

andywei1996 commented 1 year ago

@niceboygithub Yes, I’ve do it.

@niceboygithub When I put it back to wall dock it bootup well and establish WiFi connection, but I can’t telnet to S1E, console shows Connection refused.

The latest firmware was disabling telnetd so you need to flash before put it back on the wall.

@niceboygithub Thanks for your support! Finally, I flash the modified firmware successfully, following is my step:

  1. Follow telnet.md document to remove password of root user.
  2. Reboot S1E, and the device stopped after the kernel loaded. The console prompted two error messages, and a WiFi connection can't be established in this state.
  3. Put S1E back on the wall without remove UART line, and then S1E bootup successfully, WiFi connected.
  4. Follow telnet.md to flash modified firmware and install s1e2ha via UART console and it's successfully, now telnet and mosquitto work as well.

Could it be that when S1E can not communicate with wall dock, system will not boot up because S1E judgement this is not a normal state?

S1E may more power while using WiFi. If you provide enough power, it won't connect to WiFi. When you put it on the wall, the power is enough absolutely.
