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 https://github.com/jomjol/AI-on-the-edge-device/wiki/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 https://github.com/jomjol/AI-on-the-edge-device/wiki/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.
