Because of voltage level, we change voltage of SAI1/2, GPIOs, I2Cs, to 3V3. As SPF-35104_B1 and SPF-31407_C2, BOOT_MODE0/1 using VDD_1V8 pullup. Can I change to VDD_3V3? Is that change affected by sequence of Power?</P><P>Thanks</P></BODY></HTML> Fri, 06 Mar 2020 17:37:35 GMT van-tuongpham 2020-03-06T17:37:35Z Boot configure voltage https://community.nxp.com/t5/i-MX-Processors/Boot-configure-voltage/m-p/1000010#M148282 <HTML><HEAD></HEAD><BODY><P>Hi experts,</P><P>We are design board based on IMX8M mini ref board.
