10.1.2 Boot Modes Supported

The device supports several boot processes, which leverage the internal boot ROM. Most boot processes are software-driven, using the BOOTMODE[15:0] device configuration inputs to determine the software configuration that must be completed. From a hardware perspective, there are four possible boot modes:

  • Public ROM Boot when the C66x CorePac0 is the boot master — The C66x CorePac is released from reset and begins executing from the L3 ROM base address. The ARM CorePac is also released from reset at the same time as the C66xCorePac. Both the C66x CorePac and the ARM CorePac read the BOOTMODE register inside the bootCFG module to determine which is the boot master.

    • After the Boot ROM for the Cortex-A15 processor reads the BOOTMODE to determine that the C66x CorePac is the boot master, all Cortex-A15 processors stay idle by executing WFI instruction and waiting for the C66x CorePac’s interrupt. The chip Boot ROM reads the BOOTMODE register to determine that the C66x CorePac0 is the boot master, then the C66x CorePac0 performs the boot process and the other C66x CorePacs execute an IDLE instruction. After the boot process is completed, the C66x CorePac0 begins to execute the code downloaded during the boot process. If the downloaded code included code for the other C66x cores and/or the Cortex-A15 processor cores, the downloaded code may contain logic to write the code execution addresses to the boot address register for the core that is to execute it. The C66x CorePac0 can then generate an interrupt to the core causing it to execute the code. When they receive the IPC interrupt, the rest of the C66x CorePacs and the ARM CorePac complete boot management operations and begin executing from the predefined location in memory.

  • Public ROM Boot when the ARM CorePac Core0 is the boot master — The only difference between this boot mode and when the C66x CorePac is the boot master, is that the ARM CorePac performs the boot process while the C66x CorePacs execute idle instructions. When the ARM CorePac Core0 finishes the boot process, it may send interrupts to the C66x CorePacs and Cortex-A15 processor cores through IPC registers. The C66x CorePacs complete the boot management operations and begin executing from the predefined locations.
  • Secure ROM Boot when the C66x CorePac0 is the boot master —The C66x CorePac0 and the ARM CorePac Core0 are released from reset simultaneously and the C66x CorePac0 begins executing from secure ROM. The C66x CorePac0 performs the boot process including any authentication and decryption required on the bootloaded image for the C66x CorePacs and for the ARM CorePac prior to beginning execution.
  • Secure ROM Boot when the ARM CorePac0 is the boot master — The C66x CorePac0 and the ARM CorePac Core0 are released from reset simultaneously and begin executing from secure ROM. The ARM CorePac Core0 initiates the boot process. The C66x CorePac0 performs any authentication and decryption required on the bootloaded image for the C66x CorePacs and ARM CorePac prior to beginning execution.

The boot process performed by the C66x CorePac0 and the ARM CorePac Core0 in public ROM boot and secure ROM boot are determined by the BOOTMODE[15:0] value in the DEVSTAT register. The C66x CorePac0 and the ARM CorePac Core0 read this value, and then execute the associated boot process in software. Bit 8 determines whether the boot is C66x CorePac boot or ARM CorePac boot. The figure below shows the bits associated with BOOTMODE[15:0] (DEVSTAT[16:1]) when the C66x CorePac or ARM CorePac is the boot master. Figure 10-1 does not include bit 0 of the DEVSTAT contents. Bit 0 is used to select overall system endianess that is independent of the boot mode.

The boot ROM will continue attempting to boot in this mode until successful or an unrecoverable error occurs.

The PLL settings are shown at the end of this section, and the PLL set-up details can be found in Section 11.5.

NOTE

It is important to remember that the BOOTMODE[15:0] pins map to the DEVSTAT[16:1] bits of the DEVSTAT register.
