I am able to flash code to eMMC but while booting I am not observing any prints on debug terminal. I have measured the voltage and observed 0.6V on UART RXD and 0.8V on UART TXD. When we have measured on EVK it was 1.8V on UART TXD. Please suggest us how to resolve this issue.</P><P>With regards,</P><P>Suresh Gondi&nbsp;</P> Tue, 30 Apr 2024 07:36:44 GMT Suresh123 2024-04-30T07:36:44Z https://community.nxp.com/t5/Other-NXP-Products/IMX8MP-UART-Debug-issue/m-p/1857319#M22450 <P>Hi Team,</P><P>I am using IMX8MP for my custom board design.
