https://community.nxp.com/t5/i-MX-Processors/Assistance-Required-for-Booting-Linux-from-eMMC-on-Custom-i/m-p/2170586#M240753 <P>Hi,&nbsp;</P><P>We are currently developing a custom video recorder device based on the i.MX8MP SoC. At present, we are running Linux OS booting from an SD card connected via the SDHC2 interface.</P><P>Our next goal is to migrate the boot process to an eMMC device connected to the SDHC3 interface. However, our custom board does not expose a USB-OTG port. As a workaround, we followed the guidance from <A href="https://community.nxp.com/t5/i-MX-Processors/How-to-flash-eMMC/td-p/782736" target="_self">this</A>&nbsp;post and attempted to flash the eMMC using the dd command.</P><P>For this process, we prepared a bootable SD card and connected it to the SoC through a USB-A port using an SD card reader. Unfortunately, when executing the dd command, the system either hangs after copying approximately 150–170 MB of data or enters a kernel panic.</P><P>We have attached the relevant kernel logs and screenshots for your reference. We would appreciate your assistance in diagnosing and resolving this issue so that we can successfully boot Linux from the eMMC.</P><P>Thank you for your support.</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="IMX8MP_Getting_Stuck_While_DD.png" style="width: 836px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/357186i3CBC4C51AF17CEFA/image-size/large?v=v2&amp;px=999" role="button" title="IMX8MP_Getting_Stuck_While_DD.png" alt="IMX8MP_Getting_Stuck_While_DD.png" /></span></P> Tue, 16 Sep 2025 16:18:53 GMT sunilaerxlabs 2025-09-16T16:18:53Z https://community.nxp.com/t5/i-MX-Processors/Assistance-Required-for-Booting-Linux-from-eMMC-on-Custom-i/m-p/2170586#M240753 <P>Hi,&nbsp;</P><P>We are currently developing a custom video recorder device based on the i.MX8MP SoC.
