It has an EEPROM and an RTC connected to the PMIC_I2C lines.</P><P>While looking into the reference manual (IMX8DQXPRM), I found the PMIC_I2C module at section 9.1.11- SCU Pin Assignments. Does this mean that the PMIC_I2C can be accessed only from the SCFW? Can the A35 core access the above I2C?</P><P>Could someone please clarify this?</P><P>Thanks in advance,</P><P>MJames</P> Tue, 09 Jan 2024 05:44:44 GMT MJames 2024-01-09T05:44:44Z https://community.nxp.com/t5/i-MX-Processors/iMX8QXP-PMIC-I2C/m-p/1784889#M218417 <P>Hi,</P><P>I have a custom board using iMX8QXP.
