AM6422: am64x. A53 example of internal watchdog timer doesn't work

Part Number: AM6422
Other Parts Discussed in Thread: TMDS64EVM

Hi,

I am running TMDS64EVM without OS.

here is my sdk info

C:\ti\mcu_plus_sdk_am64x_09_01_00_41
tool chain:  C:\ti\gcc-arm-9.2-2019.12-mingw-w64-i686-aarch64-none-elf  download and provided by ti
gmake  C:/ti/ccs1250/ccs/utils/bin/gmake.exe   provided by ti.  Should not related. since the example compiled with tool chain. 

however, when, I run watchdog example under "C:\ti\mcu_plus_sdk_am64x_09_01_00_41\examples\drivers\watchdog\watchdog_interrupt\am64x-evm\a53ss0-0_nortos", it is not working at all.

the interrupt is not triggered.   (r5fss0-0_norts,works for sure with example)


Question, can you give me a working example of internal watchdog for A53  any core? Thanks. 


I am running under code composer, 

with  SBL,   C:\ti\mcu_plus_sdk_am64x_09_01_00_41\tools\ccs_load\am64x\sciclient_ccs_init.release.out 


then load C:\ti\mcu_plus_sdk_am64x_09_01_00_41\examples\drivers\watchdog\watchdog_interrupt\am64x-e                    
interrupt is not triggered, it stuck at while loop forever. 


Me, Jun Tu.

Thanks.
