| Boot stuck in U-Boot console without console connected          | When using the reference Carrier Board and Adapter Board without microUSB console connected to a PC, the system can get stuck in u-boot console after wrongly detecting noise as a key press.                                             | Adapter Board v1.0   | <p>Resolved by disassembling “R7” from the Adapter Board.<br><br>Fixed in v1.1.</p>                                                                                                                                                           |

U-Boot and Linux drivers failed to toggle the eMMC reset line<br>2. eMMC did not have reset signal enabled</p> | SoM v2.1 and earlier | Resolved by programming the eMMC internal RST\_n\_FUNCTION efuse to value 1, and apply [patches](https://github.com/SolidRun/imx8dxl_build/commit/b7e275cc63a318e77e213548643cea4dc962b6d5) to U-Boot (and Linux) to toggle reset before use. |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://dev.solid-run.com/nxp/imx8/com-som/imx8-dxl-som-hardware-user-manual/imx8-dxl-errata-list.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
