Q: How to bypass “Failed to get eeprom handle for cvm from eeprom manager.” error during flash?

This kind of issue generally comes from the i2c drive strength not enough on custom board design.
Need to follow the tuning guide for the I2C drive strength and modify the value inside of tegra264-mb1-bct-prod-p3834-xxxx-p4071-0000.dts.
For example,

prod@0 {
        addr-mask-data =
            /* I2C0 */
            <0xac287004 0x00f0f000 0x0000f000>,
            <0xac28700c 0x00f0f000 0x0000f000>,
            /* I2C1 */
-            <0xac287014 0x00f0f000 0x00000000>,
-            <0xac28701c 0x00f0f000 0x00000000>,
+            <0xac287014 0x00f0f000 0x0000f000>,
+            <0xac28701c 0x00f0f000 0x0000f000>,
