This page lists the possible error codes, their meaning and possible solutions.
The effective error codes can be found here.
Critical Errors
Those Errors make the normal operation of the device impossible. Most likely they are caused by a hardware issue!
0x00000001 PSRAM bad
Your device most likely has no PSRAM at all or it is too small (needs to have at least 4 MBytes)! See Hardware Compatibility.
Usually the log shows something like this:
psram: PSRAM ID read error: 0xffffffff
cpu_start: Failed to init external RAM!
0x00000002 Heap too small
The firmware failed to allocate enough memory. This most likely is a consequential error of a bad PSRAM!
0x00000004 Cam bad
The attached camera can not be initialized. This usually is because on of the following reasons:
- The camera is not supported, see Hardware Compatibility
- The camera is not attached properly -> Try to remove and attach it again. Make sure you move the black part enough into the socket!
- The camera or the camera cable is damaged
Non-Critical Errors
Those Errors can be caused by an error during initialization. It is possible that the error has no impact at all or that a reboot solves it.
0x00000100 Cam Framebuffer bad
The firmware was unable to initialize the Camera Framebuffer. The firmware will continue to work, but other consequential error might arise. A reboot of the device might help.
0x00000200 NTP failed
The firmware failed to get the world time from an NTP server. The firmware will continue to work, but has a wrong time.
