Dear ARM expert, I'm new to ARM. I am trying to use generic timer, but seems CNTFRQ register can be accessed. I saw the description in the ARM (Architecture Reference Manual) for the ARMv7-A and ARMv7...

Cortex-A15MP Core Registers

Hi, I am using ARM v7-A (Cortex A15 MP) and i want to observe the stack context, as i understand it, there are some offset values inside of ARM Core Registers (between LP, SP and PC), and the offset...
Cortex-A9 core registers

In RTL code of A9mp platform provided by ARM, I see that almost all registers are renamed and are out of order(There are registers named R0-R55). This make it quite difficult for me to debug some problems...
