Boot Configuration header – J106
The boot mode, as determined by the 12 BOOTCONFIG pins, is selected on the rising
edge of the PWRONRSTn Reset Input Pin of the AM335x processor which is controlled
by the PMIC of the MityARM-335x module. Each boot configuration pin on the
development kit is connected to a weak pull up, ‘1’, unless a jumper is placed across the
header pins which pulls that configuration pin down to ground, ‘0’.
The MityARM-335x Development Kits default boot configuration header mode is shown
in Figure 8 below. As seen this equates to a boot configuration setting of [0] to [11],
111011111111. Please reference the AM335x Technical Reference Manual for
complete details on how the vast array of boot mode options.
There are a total of 16 boot configuration pins that are registered by the AM335x
processor however [12] to [15] are fixed, 0010, on the MityARM-335x module.
