Unexpected reset code 9 #192

Closed PythonEatsSQuirreL closed 1 month ago

Since the last assembly I am getting unexpected reset code 9 after a couple of minutes of driving. Sometimes even "sd file cannot be open" or something like that, but code 9 is shown every single time. What is this code referring to?

It is the reset reason reported by the bootloader, so for 9 the reason would be RTC Watch dog Reset digital core. These errors aren't particularly useful to be honest.

The fact that you are also getting SD card errors makes me suspect there is a hardware issue, such as a bad solder joint somewhere or a bad power source.

Which version of the software did you install? I would recommend trying a stable release and flashing it with esptool as documented here which will rule out software issues.

You were right. I soldered the sd module all over again and I found one cable from the 5g module touching a pin from another module. Now the issues are solved. Thank you!
