Introduction
Silicon revision is identified by a code marked on the package. The code is of the format AM3352x or
AM3358x, where "x" denotes the silicon revision.
Table 1 lists the information associated with each silicon
revision for each device type. For more details on device nomenclature, see the device-specific data
manual.

B 2.1 Silicon revision 2.1
Each silicon revision uses a specific revision of TI's ARM
®
Cortex™-A8 processor. The ARM Cortex-A8
processor variant and revision can be read from the Main ID Register. The DEVREV field (bits 31-28) of
the Device_ID register located at address 0x44E10600 provides a 4-bit binary value that represents the
device revision. The ROM code revision can be read from address 2BFFCh. The ROM code version
consists of two decimal numbers: major and minor. The major number is always 22, minor number counts
ROM code version. The ROM code version is coded as hexadecimal readable values; for example, ROM
version 22.02 is coded as 0000 2202h.
Table 2 shows the ARM Cortex-A8 Variant and Revision, Device
Revision, and ROM Code Revision values for each silicon revision of the device.
