Macro Definition Documentation

CHIP_BL0_IDENTIFIER

#define CHIP_BL0_IDENTIFIER   0x3042544f

First owner boot stage, e.g.

BL0, manifest identifier (ASCII "OTB0").

Definition at line 52 of file chip.h.

PINMUX_PAD_ATTR_PROP_CYCLES

#define PINMUX_PAD_ATTR_PROP_CYCLES   500

Pinmux pull up/down wait delay.

After enabling the pull-up/down on a pin, we need to wait for ~5us for the configuration to propagate to the physical pads. 5us is 500 clock cycles assuming a 100MHz clock.

Definition at line 86 of file chip.h.

SW_STRAP_BOOTSTRAP

#define SW_STRAP_BOOTSTRAP

Value:

  ((1 << SW_STRAP_2_PERIPH) | (1 << SW_STRAP_1_PERIPH) | \
   (1 << SW_STRAP_0_PERIPH))

Bootstrap strap value.

We expect strong pull-ups on all software strap pins, i.e. 11_11_11.

Definition at line 131 of file chip.h.

SW_STRAP_MASK

#define SW_STRAP_MASK

Value:

  ((1 << SW_STRAP_2_PERIPH) | (1 << SW_STRAP_1_PERIPH) | \
   (1 << SW_STRAP_0_PERIPH))

Mask for the software strap pins.

Definition at line 112 of file chip.h.

SW_STRAP_RMA_ENTRY

#define SW_STRAP_RMA_ENTRY

Value:

  ((1 << SW_STRAP_2_PERIPH) | (1 << SW_STRAP_1_PERIPH) | \
   (0 << SW_STRAP_0_PERIPH))

RMA entry strap value.

We expect strong pull-ups on SW_STRAP_2_PERIPH and SW_STRAP_1_PERIPH, and strong pull-down on SW_STRAP_0_PERIPH, i.e. 11_11_00.
