Detailed Description

6.5

Identification

6.5.1

Revision Identification

For more information about Revision Identification, see Section 8.1, Device Nomenclature section.

6.5.2

Die Identification

The device part number identification data can be read in the CTRLMMR_WKUP_JTAG_DEVICE_ID

For more information about Die Identification, see Device Identification section in the device TRM.

6.5.3

JTAG Identification

The manufacturer identity, the boundary scan part number, and the silicon revision of the device can be

read in the CTRLMMR_WKUP_JTAGID register.

For more information about JTAG Identification, see Device Identification section in the device TRM.

6.5.4

ROM Code Identification

The ROM code uses several global memories in the MSRAM that are useful for debugging.

For more information about ROM Code Identification, see Global Memory Addresses Used by ROM Code

section in the device TRM.

6.6

Boot Modes

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.
