============================================================================

In the past, there was no problem.

Old, and the other thing

- Rebuild "sys_bios_driver"

- Rebuild "am335x_platform"

- Add uartstdio.c file(starterware) in project (ethercat slave) for use printf.

- CAN1 device enable.

Help would be appreciated.

That just means the debugger is unable to show the contents of the exit.c source file after the failure has occured. i.e. not the root cause.

That means the failure was caused by a dataAbort exception at Program Counter address 0x8001b41e. What is the code at that address?

Possible options:

1) In the CCS debug view open the Disassembly view. Enter the address 0x8001b41e. The function the code is in should be visible (by scrolling up), and if debugging information is available the source code should be shown intermixed.

2) From the linker .map file, the GLOBAL SYMBOLS: SORTED BY Symbol Address list should show the function name at the next lowest address.

Once you know which function the error is occuring in, should be able to set a breakpoint to investigate the cause.
