# Error
|
|
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](../Hardware-Compatibility).
|
|
|
|
Usually the log shows something like this:
|
|
```
|
|
psram: PSRAM ID read error: 0xffffffff
|
|
cpu_start: Failed to init external RAM!
|
|
```
|
|
|
|
# Status
|
|
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.
