Do all BOOTMODE and MCU_BOOTMODE pins have external pulling
resistors or a circuit to drive the desired bootmode? BOOTMODE and
MCU_BOOTMODE pins do not have internal pull-up or pull-down resistors that are
active during power up and reset. External pulling resistors can be used to set
the bootmode. Alternatively, a buffer that is only driven when reset is active
can be used to present the bootmode.
Is the expected bootmode present on the BOOTMODE and
MCU_BOOTMODE pins when PORz or MCU_PORz are active? If the bootmode pins
are redefined for another purpose during operation, they must be released and
set back to the proper levels to select the boot mode whenever the AM654x enters
the cold reset state.
