Configuration/Setup
This section discusses the board configuration.
4.1
Boot Configuration
Various boot configurations can be set using the pull-up/pull-down resistor combinations provided on the
SYSBOOT[15..0] pins. Boot configuration pins are latched upon de-assertion of the PORz pin. Refer to
the
AM572x Sitara Processors Silicon Revision 2.0 Data Manual (SPRS982)
for more details. The
AM572x IDK EVM is configured by default to 0x8106 to enable UBOOT/Linux boot from the SDCARD.
The secondary boot device selected by this boot mode is QSPI1.
4.2
I2C Address Assignments
The AM572x IDK EVM contains multiple I2C buses connected to a master port on the processor. Each
bus contains one or more I2C slave devices that must have unique addresses to prevent contention.
and
list the addresses of the I2C slave devices attached to buses I2C1 and I2C2,
respectively.
