The following chart depicts the general boot flow of SBC Lynx models equipped with NOR flash. It is worth noticing that, if the flow falls in the ''serial downloader'' branch, the BootROM performs an attempt to boot from microSD card too, as the ''Manufacture mode'' is enabled. This mode can be a convenient solution for different needs (for example, to recover a board where U-Boot was erased accidentally from NOR flash). For more information, please refer to [[How_to_create_a_bootable_microSD_card_(XUELK)|this page]] and [[Standalone_boot_(XUELK)#U-Boot|this page]].
