<p>The firmware failed to allocate enough memory. This most likely is a consequential error of a bad PSRAM!</p>

<p>The attached camera can not be initialized.
|

This usually is because on of the following reasons:
|
||||
* The camera is not supported, see <a href="../Hardware-Compatibility">Hardware Compatibility</a>
|
||||
* 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</p>

<h2 id="0x00000008-sd-card-basic-check-failed"><code>0x00000008</code> SD card basic check failed</h2>
|
||||
<p>One or more basic SD card checks failed.</p>
|
||||
<p>The following checks are performed during boot sequence:
|
||||
* Write a file (sdcard/sdcheck.txt) to SD card with some generic text
|
||||
* Read the written file back
|
||||
* CRC verification
|
||||
* Delete the file</p>

<li>Write a file (sdcard/sdcheck.txt) to SD card with some generic text</li>
|
||||
<li>Read the written file back</li>
|

<li>CRC verification</li>
|

<li>Delete the file</li>

</ul>
|

<p>Detailed error indication (write, rerad or delete error) can be derived from blinking code of red board status LED. Please have a look to !!!TODO!!!</p>
|

<p>Recommendation: Reformat SD card and check again or try another SD card</p>

|

<p>Oned or more mandatory folders and/or files are missing on SD card.
|
||||
To have early indication that SD card is potentially ready for operation, some folder and files, which are mandatory are presence checked. This is not a 100% check and a successful test does not mean everthing is OK.</p>
|
||||
<p>The following folders / files get checked during boot sequence:
|
||||
* /sdcard/config
|

* /sdcard/html
|

* /sdcard/demo --> created automatically in firmware
|
||||
* /sdcard/firmware --> created automatically in firmware

<p>Recommendation: Check logs and / or redo a Over-The-Air Update (OTA Update) to ensure proper SD card structure</p>

<p>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.</p>
