Hi,
When i run the SDK demo <hello_world_mpc5744p> on DEVKIT-MPC5744P, an error occured in "CLOCK_SYS_UpdateConfiguration()" function if i set system clock to 180MHz or 200MHz. When run to this line ,it always jump to a random address,just like image below:
If i debug the progam in step mode,it can run normally,but can't run after reset.
But while i set the system clock to 160MHz,the program can run normally.Even i press the reset buttom.
The code show as below:
Other SDK demo with those two lines can't run normally as same.
Software evn:
S32 DS for PA 2017.R1 with patch UP11. The SDK version is RTM 3.0.0
Hardware evn:
DEVKIT-MPC5744P
thanks for help.
Solved! Go to Solution.
Hi,
I tested this demo example on DEVKIT-MPC5744P ver.B and see no issue running on 200MHz after adding this clock setting.

Hi,
Thanks for help. I test the same program on another board ,it's OK. It seems to be the dev board hardware problem. But general applications can run normally,really strange.
