Power-Up Booting Process
ADSP-2106x and ADSP-21160 processors include a hardware feature that
boot-loads a small, 256-instruction program into the processor’s internal
memory after power-up or after the chip reset. These instructions come
from a program called boot kernel. When executed, the boot kernel facilitates
booting of user application code. The combination of the boot kernel
and application code comprise the boot-loadable (.ldr) file.
At power-up, after the chip reset, the booting process includes the following
steps.
1. Based on the boot type, an appropriate DMA channel is automatically
configured for a 256-instruction (48-bit) transfer. This
transfer boot-loads the boot kernel program into the processor
memory. DMA channels used by the various processor models are
shown in Table 3-1.
