PRODUCTION DATA
This device supports primary boot from the UART, I2C, OSPI, HyperBus, parallel NOR Flash, SD or eMMC™, USB, PCIe, and Ethernet interfaces. If the primary boot fails, the device also supports a secondary backup boot from the UART, I2C, OSPI (legacy SPI mode only), HyperBus, SD, USB, and Ethernet interfaces.
The Boot Mode pins (BOOTMODE[18:00] and MCU_BOOTMODE[09:00]) provide the means to select the desired boot mode before the device is powered up. It is the user’s responsibility to properly set the (MCU_)BOOTMODE pins (via pullups or pulldowns) depending on the desired boot scenario.
For more detailed information about the primary/secondary Boot Modes, including the Boot Mode pins, usage, and selections, see the Boot Mode Pins section in the device TRM.
