This page lists the possible error codes, their meaning and possible solutions.
|
|
|
|
The effective error codes can be found [here](https://github.com/jomjol/AI-on-the-edge-device/blob/rolling/code/components/jomjol_helper/Helper.h).

# 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. |
