General
- new "reset-assert" event, for systems without SRST
ARM
+ - supports "reset-assert" event (except on Cortex-M3)
- renamed "armv4_5" command prefix as "arm"
- recognize TrustZone "Secure Monitor" mode
- "arm regs" command output changed
- register names use "sp" not "r13"
- add top-level "mcr" and "mrc" commands, replacing
various core-specific operations
- - basic semihosting support
+ - basic semihosting support (ARM7/ARM9 only, for now)
ARM11
- - Preliminary ETM and ETB hookup
- - accelerated "flash erase_check"
- - accelerated GDB memory checksum
- - support "arm regs" command
- - can access all core modes and registers
- - watchpoint support
+ - Should act much more like other ARM cores:
+ * Preliminary ETM and ETB hookup
+ * accelerated "flash erase_check"
+ * accelerated GDB memory checksum
+ * support "arm regs" command
+ * can access all core modes and registers
+ * watchpoint support
+ - Shares some core debug code with Cortex-A8
Cortex-A8
- - support "arm regs" command
- - can access all core modes and registers
- - supports "reset-assert" event (used on OMAP3530)
- - watchpoint support
+ - Should act much more like other ARM cores:
+ * support "arm regs" command
+ * can access all core modes and registers
+ * watchpoint support
+ - Shares some core debug code with ARM11
Cortex-M3
- Exposed DWT registers like cycle counter
- vector_catch settings not clobbered by resets
