Hello,I met a HAL_Delay() block. The board worked with internal RCC, and I checked the uwTickFreq when debugging, it always equal to 0. Attached the ioc file.
Actually, this issue here refer to the setting of "TrustZone". If I negative this option when starting the project, the HAL_Delay worked. Why does this setting impact the Systick?
Sarrs.S ,thank you.I checked that the HAL_InitTick return OK. The tickStart can't get the right value to, It always equal to 0 or 0xffffffff..And in order to check the Internal Clock, I try to run a 50ms TIM2, but it stilled failed.
