I am trying to understand how it works. What is actually loaded when the SoC boots in Serial Downloader Mode? What component is responsible for controlling this process? I do not know whether this behavior is hardware-dependent, but if it is, I am referring specifically to the i.MX93 EVK.</P><P>Thank you for your time.</P> Wed, 07 Jan 2026 12:14:09 GMT https://community.nxp.com/t5/i-MX-Processors/How-does-Serial-Downloader-work/m-p/2289451#M243219 FerranFE 2026-01-07T12:14:09Z https://community.nxp.com/t5/i-MX-Processors/How-does-Serial-Downloader-work/m-p/2289614#M243223 <P>Hello&nbsp;<a href="https://community.nxp.com/t5/user/viewprofilepage/user-id/247760">@FerranFE</a>&nbsp;</P> <P>I hope you are doing very well.</P> <P>&nbsp;</P> <P>The ROM code is the component in charge of Boot mode selection.
