 SBC Lynx is extremely flexible in terms of hardware configurations. This document describes main options related to booting. In case you need a configuration that is not listed here, please contact [mailto:sales@dave.eu |
IntroductionEdit
SBC Lynx is built upon NXP iMX6UL processor. This component supports several booting options that are summarized here. Reading of that section is recommended for understanding this document.
Interested reader may find an exhaustive discussion of iMX6UL boot options in the Applications Processor Reference Manual[1].
Available optionsEdit
By default, eFUSE bits are not supported as bootstrap option [1]. Thus two actual modes can be selected by S12.1 and S12.2 switches, as listed in the following table.
| BOOT_MODE[1:0] | Boot type | S12.1 | S12.2 | Notes |
|---|---|---|---|---|
| 00 | Boot from eFUSEs | |||
| 01 | Serial downloader | |||
| 10 | Internal boot | |||
| 11 | reserved |
Generally speaking, three main boot modes are supported. These modes are selected by BOOT_MODE signals that are latched when processor comes out of reset.
