On your EVK, you have put 0.92V. On power file, it is somtime 0.85 or 0.9V.</P> Wed, 20 May 2026 08:04:14 GMT https://community.nxp.com/t5/i-MX-Processors/VDD-SOC-voltage/m-p/2368222#M245294 sesa462683 2026-05-20T08:04:14Z https://community.nxp.com/t5/i-MX-Processors/VDD-SOC-voltage/m-p/2369136#M245301 <P style="margin: 0in; font-family: 'Segoe UI'; font-size: 10.5pt;">According to available NXP documentation, VDD_SOC is associated with different SoC driving modes.
