S32_SDK for 5744P clock_manager module error

[youyuan_yue]

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.

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.
