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.
So how can I match them with R0-R14, especially for SP and LR ?
In general what gets sent over the JTAG interface is designed to match the architectural state - so for most software debug I would recommend using the debug interface, it is less likely to drive you crazy =)
