Summary: CYGNUM_HAL_EXCEPTION_MIN for cortexm arch seems
incorrect
Product: eCos
Version: CVS
Platform: stm3240g_eval (ST STM3240G-EVAL board)
OS/Version: Other
Status: UNCONFIRMED
Severity: normal
Priority: low
Component: Kernel
AssignedTo: unassigned@bugs.ecos.sourceware.org
ReportedBy: richard.morris@lifetech.com
CC: ecos-bugs@ecos.sourceware.org
Class: Advice Request
This is my first ecos bug submittal. Please provide guidance if this is not
correctly done.
When Ecos is configured for POSIX support (and maybe otherwise), the
CYGNUM_HAL_EXCEPTION_MIN is set to CYGNUM_HAL_EXCEPTION_DATA_UNALIGNED_ACCESS.
When the kernel initializes and builds the exception table, the assertion that
checks the exceptions being built against CYGNUM_HAL_EXCEPTION_MIN fails.
It appears that the correct value should be
CYGNUM_HAL_EXCEPTION_DATA_TLBMISS_ACCESS.
Current cvs trunk of: ecos/packages/hal/cortexm/arch/current/include/hal_intr.h
#define CYGNUM_HAL_EXCEPTION_MIN CYGNUM_HAL_EXCEPTION_DATA_UNALIGNED_ACCESS
Correct value:
#define CYGNUM_HAL_EXCEPTION_MIN CYGNUM_HAL_EXCEPTION_DATA_TLBMISS_ACCESS
