Boot QEMUVPB

The QMEU system emulator (qemu-system-arm) will load this code at address 0x00010000 onwards and set the following registers before jumping to this code.


R0 - Zero

R1 - Machine Type (Versatile_PB = 0x0183)

R2 - Address of the ARM Tags structure (Normally 0x0100)


On entry to this code the processor will be in the following state:


World - Secure

Mode - Supervisor (ARM_MODE_SVC)

MMU - Disabled

FPU - Disabled

L1 Data Cache - Disabled

L1 Instruction Cache - Disabled

Branch Predication - Disabled

Unaligned Data Access - Disabled


Ultibo switches the processor to System mode for all operations and remains in the Secure world.

The initialization process enables the MMU, FPU, L1 Cache and other performance optimizations.
